...Dimethyl sulfide. once an evil-smelling waste left behind in kraft-papermaking, is being used to give an odor to natural gas, which otherwise could seep through a house without being detected. Scientists think they may also be able to use the chemical as a starting material for making a permanent antifreeze...
...Hartman and George H. Mangun of Detroit's Henry Ford Hospital think they have found a way to sterilize the blood and kill the virus without making the blood harmful or useless. They have used nitrogen mustard, a war gas, and are now experimenting with a chemical called dimethyl sulphate. To prove the process safe, Dr. Hartman subjected himself to three transfusions. He felt all right afterward. Then he gave sterilized plasma to several hundred patients; none got jaundice (untreated blood that contains the virus causes jaundice in 5% to 7% of patients...
...rubbers. Butadiene molecules were first polymerized-or built up into larger molecules-with the help of metallic sodium, making a stretchy substance which its German inventors about 1927 called Buna (Bu for butadiene, Na for sodium). It was not a very satisfactory synthetic: but better than the methyl rubber (dimethyl butadiene) of World War I, when it was said German Army trucks often had to be jacked up overnight so that their solid tires would not flatten out permanently under their weight. German chemists soon discovered ways to make superior products by combining butadiene with other substances and co-polymerizing...
...William Russell Levis & Edward Lewis Axelman of Philadelphia call theirs a "Modern Method for Prevention of Postoperative Distention." They depend upon a newly synthesized drug to keep the bowels moving and expelling any gas which may form. The drug: dimethyl-carbamic ester of 3-hydroxyphenyl-trimethyl ammonium methyl-sulphate, a chemical compound which has been telescoped to prostigmin. Drs. Levis & Axelman inject small amounts of prostigmin "at the time of operation or shortly thereafter and continue injections for 24 to 48 hours at four to six hour intervals, or until such time that we feel the condition of the patient...
...drug which most often causes granulopenia in the U. S. is amidopyrine (chemical name: dimethylamrno-phenyl dimethyl pyrazolone). Related drugs which Dr. Kracke also blames are: pyramidon, phenacetine, arsphenamine. neoarsphenamine, amytal compound, allonal, peralga, amidophen. Dinitrophenol causes the rapid oxidization of sugar and fat in the body. This year it killed at least two overeager fat-reducers (TIME, April 30). Dr. Kracke said he feared it would be exploited this winter as a weight reducer...
