Necrology A. HENRIKSEN IT I S with regret that we announce the death of A. Henriksen on September 5, 1932. from cerebral hemorrhage. Mr. Hen riksen was chief chemist of the Continental Oil Co., Ponca City, Okla., and had been a member of t h e AMERICAN CHEMICAL SOCIETY since 1922.
HERMAN PAUL SACHSE HERMAN- P A U L SACHSE, who had devoted his life to the design
and production of scientific instruments, both in America and Germany, died in the Passavant Memorial Hospital in Chicago, 111., August 12, 1933, a t the age of 53. At the time of his death, he held the position of factory manager with the Central Scientific Co. in Chicago. Mr. Sachse, who was born in Germany, first entered the scientific instrument industry as an apprentice in the Zeiss Opti cal Works in Jena. H e later became associated with Toepfer and Sohn in Pottsdam. In 1911, he came to America t o accept a position as superintendent in the plant of the Eugene Dietzgen Co. in Chicago. His skill in the testing and inspection of optical instruments later opened an opportunity to enter the employ of the Bausch & Lomb Optical Co. in Rochester, Ν . Υ., as general inspector. In 1918, t h e Central Scientific Co. secured his services in the production of optical devices for the control of gun fire in the great war. A t the close of the war, he assumed full charge of the production of scientific instruments and laboratory appa ratus in the factory of this company, first as factory superinten dent, and later as factory manager. Mr. Sachse's unusual ability as an apparatus and instrument designer enabled him to design instruments of precision, which could be produced economically in small quantities, but still of the proportions and appearance that fine instruments justify. He found ample opportunity for the use of his talents in the latter months of his life in the development of manufacturing designs and the production of numerous exhibits for the basic sciences in the Hall of Science of A Century of Progress Exposi tion i n Chicago. Unfortunately, he was denied the pleasure of seeing the exhibits, although he could see t h e buildings of the World's Fair from his hospital window. Mr. Sachse is survived by two daughters, Marguerite and Vir ginia, and a son, George.
Utilization of Pyridine-Quinolines for Removal of Phenol from Coke-Plant Effluents L. KOSACHKOV, Charcov, U. S. S. R.
T H E COAL-CHEMICAL INSTITUTE at Charcov, Russia, has been studying new materials for the removal of phenol from coke-plant effluents. Their previous work showed that the use of different extraction agents for the dephenolation of plant effluents gave satisfactory results only when the extracting medium united with the phenols. Aniline, pyridine, and quinoline were first used for extraction of phenol. Quinoline was finally chosen be cause of its low solubility in water, as only 0.24 per cent of the pyridine-quinoline mixtures dissolved in water during the e x traction process. This gave less toxicity in the treated effluent. The presence of high boiling quinoiines, in anthracene oil of boiling point 280° to 360° C , that were insoluble in water made possible the new method of extracting phenol from plant ef fluents. The analysis of anthracene oil from six different plants showed a specific gravity of 1.08 t o 1.118; a phenol content of 1.2 to 8.0 per cent; and a pyridine-quinoline content of 1.9 t o 8.0 per cent. T h e extraction property of the pyridine-quinoline mixture was studied by using a 30 per cent solut ion in benzene, and shaking with a phenol solution containing 2.0 grams of phenol per liter. A series of five tests showed an average extraction of 91.8 per cent, t'sing tar water from the test coke installation in Charcov, t h e extraction process was also studied, but because of its low phenol content, phenol was added t o a concentration of 0.21 per cent. The average of five tests showed 92 per cent removal of phenol. Some preliminary data showed that t h e 30 per cent quinolinebenzene solution would extract phenol from effluents about 6 0 times when the concentration was 0.2 per cent. T h e quinolinebenzene solution was readily regenerated by treatment with a 1 per cent sodium hydroxide solution, the phenolates being sepa rated and the quinoline-benzene oil recovered. T h e regenerated oil w a s just as effective as the original oil for extracting phenols.

An attempt was made t o use anthracene oils for extraction of phenol in place of t h e quinoline-benzene oil. T h i s method would eliminate the use of large quantities of benzene. A 2 per cent phenol solution was extracted with 60 parts of oil to 100 parts of phenol effluent; the 60 parts of oil were made from 30 parts of anthracene oil and 3 0 parts of benzene. T h e average of a series of six tests gave 71.2 per cent removal of phenol. T h e same pro cedure was applied t o t h e phenol-bearing effluents, which gave 75 per cent phenol removal. I t was found that with t h e anthracene oil alone, in the ratio of 60 parts of anthracene oil t o 100 parts of effluent, 77 per cent of the phenol was removed. For complete saturation 1 c c . of quinolines required about 2 grams of phenol. Oils and waste waters containing quinolines were found toxic to fish. It was feit that b y suitable dilution with other wastes and in streams such quinoiine-treated effluents would become unobjectionable. The Coal-Chemical Institute anticipates t h a t this process will be tried soon on a semi-commercial scale. Abstracted by L o u i s SHNIDMAN VASCOLOY-RAMET C O R P . F O R M E D

F O R THE F I R S T T I M E stainless-clad steel has been used i n the construction of an autoclave recently installed i n a soap works. T h e autoclave is 6 feet in diameter, 26 feet long, with walls 13/ie inch thick and heads 1 inch thick, all of IngOclad stainless-clad steel, having a 20 per cent thickness of 18 and 8 stainless steel on the interior. T h e steel was furnished b y t h e Ingersoll Steel & Disc Co., division of t h e Borg Warner Corp., Chicago, 111., and fabrication was handled by the Hamler Boiler & Tank Co., Chicago. The entire autoclave w a s built of butt-welded stainless-clad plates. Coated stainless welding rods of 2 5 per cent chromium and 12 per cent nickel composition were used for welding the interior of t h e vessel, and mild steel rod for the soft steel side. T h e autoclave was built under standard A. S. M. E . Class 2 specifi cations for pressure vessels, and approved after undergoing a test at 250 pounds pressure. CALCENE
T H E COLUMBIA ALKALI CORP., Barberton, Ohio, has recently
put on the market a new reinforcing calcium carbonate pigment for rubber. It is a precipitated product of extremely fine particle size, running over 9 8 per cent under 0.4 micron. The surface of the particles is coated with approximately 2 per cent of a rubbersoluble organic material which prevents cementation of the indi vidual particles and gives complete dispersion of the pigment in rubber. Calcene gives tensile, tear, and abrasion-resistance values con siderably higher than other reinforcing rubber pigments, except t h e gasjblacks. A t approximate loadings tensile and tear-resist ance values, hitherto obtainable only with soft g a s black, c a n be reached with Calcene. I t s use is indicated i n rubber stocks requiring high tensile and high resistance t o tear and abrasion, especially where a black stock is not desired, or where a relatively soft modulus is desired along with the high physical properties. PATTERSON U N I P O W E R AGITATOR
DRIVE
T H E LATEST ADDITION to t h e line of agitators, mixers, and stirrers manufactured b y The Patterson Foundry & Machine Co., East Liverpool, Ohio, is the unipower agitator. T h i s is built in both vertical and horizontal types and, when using 1800 r. p. m. motors, will produce shaft speeds down t o less t h a n one revolution per minute without the use of gears. While one-way or two-way agitation can be accomplished without noise, vibra tion, or grease slop, and heavy, continuous loads or momentary overloads as high a s 400 per cent can be carried, the unit is com pact and light, making it especially attractive for installation over tanks and vats.
