CAS Names First Advisory Board Eighteen representatives of industry, education, and government make up initial board Eighteen leaders in industry, education, and government have been appointed to an advisory board established by Chemical Abstracts Service to help it cope with the many new problems created by the chemical literature explosion. Need for the board, according to CAS director Dale B. Baker, stems mainly from the fast-growing CAS research and development program, especially in the area of computer handling of chemical information. Up to now, CAS has had no formal advisory board although it has availed itself of the counsel of numerous outside editors, each an authority in his special field. The magnitude of CAS operations is now such that this sys-
tem of editorial assistance must be augmented by an advisory board, Mr. Baker explains. Like similar boards serving various ACS publications, the new CAS group will function in a purely advisory and voluntary capacity. Its members will be consulted on such matters as academic, industrial, and governmental information needs; cooperative programs with non-ACS information groups; and technical but nonchemical problems. Major areas of board assistance envisioned by Mr. Baker include: evaluating the needs of Chemical Abstracts users; acting as a sounding board for new ideas; uncovering new areas for research and development
activity; and improving CAS public relations, including relations with interested government and private groups. Membership in the new board will be for periods of one, two, and three years to start, and for three-year terms thereafter. The board is one of 14 now serving ACS publications. Its members are: John S. Ball, research director, U.S. Bureau of Mines Petroleum Research Center, Bartlesville, Okla., and chairman of the Society's Council Committee on Publications; Dr. Howard T. Bonnett, director in charge of data and information center, G. D. Searle & Co., Chicago; Walter M. Carlson, director of technical information, Department of Defense, Washington; Melvin S. Day, director, National Aeronautics and Space Administration Scientific and Technical Information Division, Washington. Also, Dr. William W.

Basic Research at Sun Oil Company
Discovery: The Transition Behavior of Waxes The scientist shown above is Dr. David S. Barmby, Research Physicist at Sun's Marcus Hook Research Laboratory (B.Sc, Ph.D., Physics, University of Leeds, England; Associate of the British Institute of Physics; Member of the American Physical Society; and Member, Philadelphia Catalyst Club). Dr. Barmby and his team of researchers are engaged in an extensive study of the physical behavior of paraffin waxes. The purpose of this study is to discover the true nature of wax solid-solid and solidliquid phase transition processes and to determine the relationships that exist between fundamental and technological properties of waxes. This basic research activity, which is essential to the Company's continuing development of new and improved wax products, involves a combination of techniques—X-ray diffraction, differential

thermal analysis and volume dilatometric measurements. Progress to date has been significant, as reported in a recent paper.* Dr. Barmby's studies reveal that three different types of transition behavior are encountered. Firstly, paraffin waxes melting below about 60°C exhibit two solid-solid transitions below their melting point. The lower transition is a lattice transition including both a volume and a latent heat change. The second transition, at a higher temperature, involves a gradual change from an orthorhombic to a hexagonal lattice structure with no discrete volume change and no observable latent heat. There is, however, a discontinuity in the thermal expansion coefficient at this second transition point. The second type of transition behavior is encountered in waxes melting in the range 60-75°C. In these waxes, only a single transition occurs below the melting point and this transition always involves both a volume and a latent heat change. The third type behavior is found in the high melting point waxes where, as is well known, no solid-solid transitions are identified below the melting point. In the first and second types of behavior, the endothermic transition occurs when the orthorhombic (110) and (020) lattice spacings reach critical values. In paraffinic waxes this criticallity appears as a constant specific volume at the transition point. Particularly significant to the wax technologist is the fact that these studies correlate, for the first time, the findings of the three techniques used, namely, X-ray diffraction,
differential thermal analysis and volume dilatometric measurements. Dr. Barmby's work has also resulted in a number of significant findings relative to wax crystallization, i. e., that the crystallization process is independent of both the melting point and the paraffinic hydrocarbon composition, that the process occurs by a two-dimensional growth mechanism involving secondary nucleation, and that the growth rate is diffusion controlled. Other studies have included investigations of the phenomena encountered in quenched wax films on paper substrates as well as the effect of polymer additives on the fundamental behavior of paraffin waxes. The work of Dr. Barmby and his team is just one of many important major research programs currently under way at Sun. These programs, conducted at four separate research iabs across the country, are led by other renowned scientists, are carried out by hundreds of R&D personnel and delve into such interesting and diverse subjects as: mechanisms of chemical reactions, microbial behavior in hydrocarbon media, synthesis of new organic compounds, and certain aspects of plasma physics.

Local Sections Launch New Publications Three local sections—Puerto Rico, Midland, and Cincinnati—have brought out new publications for their members. BORINCHEM is the title of the Puerto Rico Section's publication, launched last fall. Editor of the quarterly, published March to December, is Dr. H. Harry Szmant of the chemistry department of the University of Puerto Rico. Leonardo Igaravidez is business and advertising manager. The bulletin is distributed to members of the section, secretaries of local sections, editors of local publications, and chairmen of all local professional organizations. BORINCHEM reports section activities, and, in a special feature, presents "Silhouettes of Chemical Industries in Puerto Rico," done in cooperation with industry. The quarterly is supported by paid advertising. Volume 1, No. 1 of The Midland Chemist appeared in April. It will be published monthly, September through May. Dr. Joseph E. Dunbar is the editor; Dr. W. B. Neely is business manager.
The bulletin gives news and announcements of section interest and serves as a sounding board for comments and opinions on professional matters by individual members. It is supported in part by paid advertising. Cincinnati's CinTacs is a singlesheet multilith newsletter designed to keep members informed of section activities. Mary Ellen Puthoff of Procter & Gamble is the editor.
