Think 1Η3ΛΝΙ Emulsions. Then Think of Us! Swift's Solar Emulsifier F-221 is a fine product. But it does have one drawback. Too few people think in terms of its primary application . . . invert (water-in-oil) emulsions. If you happen to be a water-in-oil thinker, then you should try this 100% active emulsifier. It's readily soluble in diesel, mineral, or paraffin oil, alcohols, and many common solvents. As little as 112 to 1-112% (basis the total) will form emul sions containing as little as 10% oil. The water can be fresh, acidic, alkaline, or saline. No heating is necessary, you just mix.
If you're not already invert-oriented, think about it. Where can you use a creamy, viscous, highly stable, freeze-thaw and heat-resistant emulsion in the relatively low-cost range? When you get an idea, call us for a sample of Swift's "Chemical Power" . . . that's a sample of Swift's Solar Emulsifier F-221 plus solid technical assistance. Note. Swift's Solar F-221 can also be used to prepare noninvert emulsions of fats and oils (such as soybean oil), and can be used in conjunction with other, more hydrophy/ic, emulsifiers or detergents to form extremely stable, noninvert emulsions.

Dr. Eugene G. Rochow's discovery in 1941 of a method of synthesizing organochlorosilanes directly rather than through Grignard reactions was a major factor in making silicone production a commercial possibility. This discovery plus the continuing stream of research in silicon chemistry that followed, and still follows, is responsible for Dr. Rochow's winning the 1965 Frederic Stanley Kipping Award in Organosilicon Chemistry sponsored by Dow Corning Corp. The award was presented at the ACS meeting in Detroit last week by Dr. Arthur J. Barry of Dow Corning. Dr. Rochow made his early major discoveries in organosilicon chemistry at General Electric, where he worked from 1935 until 1948. He then moved to Harvard University where he is now a full professor. At Harvard, he continued his research on organosilicon compounds, silicates, and related compounds of germanium and tin. His more recent work in organosilicon chemistry has centered on silazanes, the nitrogencontaining analogs of the silicones. These compounds contain at least one silicon-nitrogen bond. From silazanes it has been possible to make "ribbon" polymers as well as metal coordination polymers. This work has opened up new approaches to silicon polymer chemistry and the more general field of inorganic polymers. Dr. Rochow was one of the first chemists to use low-resolution NMR to investigate polymer structure. He showed that molecular motion in siloxane polymers is important in determining siloxane polymer properties. Further work with high-resolution NMR showed the importance of d7r-p7r bonding between silicon and
oxygen. His work on organosilicon chemistry led him to relate the chemistry of silicon to the chemistry of other Group IV elements. In this work, he redetermined the electronegativities of the Group IV elements, since the observed chemistry of germanium in particular was not in line with its assigned electronegativity. In addition to his research, Dr. Rochow has taken a great interest in teaching. He has directed postdoctoral, graduate, and undergraduate research. He has served on the local school board and the Citizen's Advisory Committee on Education in suburban Winchester, Mass. (where he lives with his wife and three children), has reported on scientific education abroad on a Ford Foundation grant, and conducts a special program for able freshmen at Harvard. Dr. Rochow was born in 1909 in Newark, NJ. He received his doctorate at Cornell in 1935. His research was in organometallic compounds and free fluorine under Dr. L. M. Dennis. Dr. Rochow serves on the advisory boards of several scientific journals and edited a volume of "Inorganic Syntheses.>, He has won the Baekeland Medal of the ACS North Jersey Section, the Perkin Medal of the Society of Chemical Industry, and the Myer Award of the American Ceramic Society. His book on silicones has appeared in five languages. He has also published a book on organometallic compounds (with R. N. Lewis and D. T. Hurd), an introductory textbook (with M. K. Wilson), and a popular paperback on organometallic chemistry. He has been a member of the National Research Council since 1948. APRIL

Dr. Gertrude E. Perlmann
Dr. Gertrude E. Perlmann, associate professor at Rockefeller Institute, New York, N.Y., is this year's recipient of the Garvan Medal. The medal is presented each year "to recognize dis tinguished service to chemistry by women chemists, citizens of the U.S." The medal was presented at the ACS meeting last week in Detroit by Dr. H. Gladys Swope, chairman of the Women's Service Committee of ACS. Dr. Perlmann's contributions have been primarily in the study of protein structure, particularly enzymic ac tivity. The work that first made Dr. Perl mann widely known was her skillful use of electrophoresis in a variety of investigations. Her skill and attention to details made it possible for her to show clear-cut results of minor changes in proteins. She demonstrated changes in electrophoretic mobility in ovalbumin-plakalbumin transition which gave important clues to in vestigators at the Carlsberg Labora tory (Copenhagen) and contributed to their elucidation of the reaction. Dr. Perlmann was one of the first to realize the possible importance of phosphate in proteins. She demon strated that as little as one mole of phosphate per mole of protein may serve in the stabilization of the threedimensional protein structure. She showed that the single phosphate group in pepsin forms a diester linking two sites of the polypeptide chain to form a cyclic loop. This work has led Dr. Perlmann into a thorough investigation of many of the properties of pepsin. She has correlated enzymic activity with struc tural changes in both pepsin and pep sinogen.
Dr. Perlmann has published ex tensively in the field of protein and enzyme chemistry. Her recent pub lications are concerned with the reduc tion of disulfide bonds, the introduc tion of side chains by methods used in forming amino acid polymers, and immunological properties. From the results, Dr. Perlmann showed that the transition from pepsinogen to pepsin involves conformational changes with loss of most of the helical structure of the pepsinogen. Also, this work showed the relations of certain side groups to the three-dimensional struc ture of a protein. Born in Reichenberg, Czechoslo vakia, Dr. Perlmann received her D.Sc. in chemistry and physics from the German University of Prague in 1936 under Prof. Reinhold Fiierth and the late Prof. Hans Meger. In 1939 she came to the U.S. and joined the physical chemistry staff at Harvard medical school. She became a nat uralized citizen in 1945, the same year she took the position of visiting investigator at Rockefeller Institute. Dr. Perlmann has had widespread recognition of her contributions to pro tein and enzyme chemistry. She has been invited to lecture at universities and to take part in symposiums all over the world. She has lectured at Har vard medical school, Cornell Univer sity, Dartmouth medical school, the Weizmann Institute of Science in Rehovoth, Israel, and the Hebrew Uni versity, Jerusalem. She was a par ticipant in the Symposium on Molec ular Structure and Biological Function in Stockholm, Sweden, in the Antibody Workshop Meeting at St. Mary's Hos pital in London, England, and other meetings in Europe.

Unichlor tends to lower plasticizing costs while increasing viscosity in the preparation of vinyl plastisols. In paint formulation, it improves flexibility, adhesion and increases water resistance. In cutting oils, Unichlor is inert to bacterial growth, possesses inherent lubricity, good stability and is odorless and non-corrosive. Its flame retardant qualities are always good, particularly when it is combined with antimony salts.

Stop Sprouts In
Ipatief
Dr. Robert H.Wentorf, Jr.
Spuds Vapors of nonyl alcohol, a derivative of Emfac® 1202 Pelargonic Acid, have been found to be effective in inhibiting the sprouting of stored potatoes.* The method of application is simple. Air from a small fan is blown over wicks which dip into a reservoir of the liquid. Only % of a gallon per million cubic feet of ventilating air is needed. While suppressing sprouts may not be your problem, you'll probably still want to give pelargonic a close examination. This versatile C9 aliphatic acid has found practical usage in plasticizers, vinyl stabilizers, surface coatings, synthetic lubricants, amine condensates and as an agent in ore flotation. A water-white liquid with outstanding color stability, its oddcarbon chain length provides it and derivatives with greater solubility, better low-temperature flexibility or fluidity and lower melting points— generally unobtainable by averaging C 8 and Cio properties.
The 1965 Ipatieff Prize was awarded last week to Dr. Robert H. Wentorf, Jr. of General Electric. The prize, which recognizes outstanding chemical research in catalysis or in highpressure chemistry, consists of a certificate of accomplishment and $3000. Presentation was made at the ACS Detroit meeting by Dr. Robert L. Burwell, Jr., Northwestern University. Dr. Wentorf completed his chemical engineering doctoral thesis, on critical points of gases, at the University of Wisconsin in 1952 under Dr. Joseph O. Hirschfelder. He then joined General Electric's research labs in Schenectady, N.Y. There he joined a group that had been formed in 1951 to do research in high-pressure chemistry. Dr. Wentorfs contributions in highpressure chemistry have been frequent and important. Highlights of his work:

• Discovered, with H. P. Bovenkerk, a process for diffusing boron into both natural and synthetic nonconducting diamonds to make them semiconducting.
• Produced new forms of matter by high-pressure processes, such as two new forms of silicon, a new form of boron, a new form of carbon intermediate between graphite and diamond (with Bundy), and high-density forms of boron arsenate and boron phosphate (with W. L. Roth and J. D. MacKenzie). As a research associate at the GE labs, Dr. Wentorf is still looking for new forms of matter to be made at high pressures. "High-pressure work's greatest current importance," says Dr. Wentorf, "is in the study of solid-state physics and in geology. The field is captivating and difficult to turn away from," he adds, "even if some of the compounds don't look promising." Recently, for example, Dr. Wentorf studied the thermal decomposition of hydrocarbon compounds at pressures of about 150 kilobars (about 148,000 atmospheres). "At these pressures," he says, "diamond is stable and diamond can even form directly from solid graphite. Nevertheless, some of the compounds, especially the aromatics, produced graphite as the intermediate product. The aliphatic hydrocarbons, on the other hand, simply lost hydrogen and sort of collapsed toward a diamond structure. One wonders whether similar processes took place inside the primeval earth A charter member of the Geochemical Society, Dr. Wentorf hopes to help unravel some geochemical mysteries. He looks forward some day to visiting Canyon Diablo in Arizona to study the diamonds occurring in meteorites. In 1955 he synthesized garnet from natural hornblende taken from Gore Mountain in New York.
