Blocky, bristly Professor Bosch was a collaborator of Dr. Fritz Haber, whose process for extracting nitrogen from the air was recognized by the Nobel award of 1918. To utilize the Haber-process nitrogen Dr. Bosch designed a mechanism for the industrial production of ammonia, combining air-nitrogen with hydrogen under a pressure of 200 atmospheres at a temperature of 500-600° C. in the presence of a catalyst. As manager of the Badische Anilin-& Soda-Fabrik he built the Oppau ammonia works, without which Germany, cut off from nitrate-producing Chile, might have lost...
Three enthusiastic young chemists of E. I. du Pont de Nemours & Co. arose and addressed the Rubber Division of the American Chemical Society at Akron to describe the following experiment: By catalytic polymerization of acetylene they had produced mono-vinylacetylene. This they had treated with hydrogen chloride to obtain chloroprene. Polymerization of the chloroprene had resulted in a sub stance similar to the product obtained by vulcanizing rubber with sulphur. Stopping the polymerization at an intermediate point gave them ? Rubber. In short, they had produced synthetic rubber from acet ylene (product of coal and limestone), salt and water. While...
Experiments continued at the du Pont Co.'s Jackson Laboratories and in Father Nieuwland's laboratory at Notre Dame. The chemists gave up working on divinylacetylene and concentrated on the more homely mono-vinylacetylene. They treated it with hydrogen chloride and first thing they knew they had a fine pot of chloroprene. Chloroprene differs from rubber's polymer, isoprene, only in that a chlorine atom replaces the methyl group, so after that the going was fairly easy. They had only to polymerize the chloroprene to the right point, and all of them were experienced polymerizers. When they finished they...
...medal, named for his late father, to honor important industrial research. First Schoellkopf medalist, named last week, is President Frank Jerome Tone, 63, of Carborundum Co., who helped develop that and other synthetic abrasives, who originated the first commercial process for producing silicon metal (used in electrical transformers, alloys, hydrogen manufacture), who possesses "to an unusual degree the rare combination of the qualities of the pure scientist, the plant engineer, and the successful business administrator." Graduates of Hill School and Cornell of six or seven years ago wondered if President Tone is any relation to popular, broadshouldered Jerry Tone...
...balloons, filled with natural gas instead of thrice-more-buoyant hydrogen, floated sluggishly into a mushy sky over Akron one afternoon last week. They were to race for two of the three places on the U. S. Team in the James Gordon Bennett International Balloon Race in September.* Heavy rains beat two of the bags to earth within 20 mi. of the start. Storms that night brought down three more. Last to land was the Navy's entry, piloted by Lieuts. T. G. W. ("Tex") Settle and Wilfred Bushnell, at Marilla. N. Y., winning with the unimpressive distance...
