Methyl ethyl disulfide

In soft cheeses, such as Brie, Camembert, and Limburger, the following sulfur compounds were implicated 3-(methylthio)propanol, MT, DMS, DMDS, DMTS, dimethyl tetrasulfide, methyl ethyl disulfide, diethyl disulfide, 2,4-dithiapentane, 3-methylthio-2,4-dithiapentane, methional, 2,4,5-trithiahex-ane, 1,1-fe-methylmercaptodisulfide, methyl thioacetate (=methanethiol acetate), benzothiazole, methylthiobenzothiazole, methyl ethyl sulfonate, methyl methane thiosulfonate, thiophene 2-aldehyde, and H2S.34 Many of these were only present in small amounts Limburger cheese was notable for 13.2% of DMDS, 0.5% of methyl thioacetate, and 0.8% of DMTS. 

Evidence of primary S-S cleavage is further substantiated in the case of unsym-metrical disulfides obtained from photolysis of mixtures of disulfides In the case of methyl and ethyl disulfides, (methyl ethyl disulfide) = 494, indicating a chain mechanism is operative . 

Ethylene Cyanohydrin. This cyanohydrin, also known as hydracrylonitnle or glycocyanohydrin [109-78-4] is a straw-colored Hquid miscible with water, acetone, methyl ethyl ketone, and ethanol, and is insoluble in benzene, carbon disulfide, and carbon tetrachloride. Ethylene cyanohydrin differs from the other cyanohydrins discussed here in that it is a P-cyanohydrin. It is formed by the reaction of ethylene oxide with hydrogen cyanide.

SO as to end the air mixture to adsorber No. 2. The system is then fully automatic. Solvents which have been successfully recovered by the activated carbon adsorption method include methanol, ethanol, butanol, chlorinated hydrocarbons including perchlorethylene, which boils at 121 C (250 °F), ethyl ether, isopropyl ether, the acetates up to amyl acetate, benzene, toluene, xylene, mineral spirits, naphtha, gasoline, acetone, methyl ethyl ketone, hexane, carbon disulfide, and others.

The liquid phase photolysis of dimethyl disulfide (2537 A) has been reported to produce dimethyl sulfide and dimethyl trisulfide in equal quantities, and traces of CH4 and methyl tetrasulflde. Ethyl disulfide again gave mono, tri- and tetra-sulfides with a trace of ethyl mercaptan. All irradiations were prolonged, of the order 24-48 hours. It was claimed that C-S fission in the primary photolytic dissociation...

Very few sulfur-bonded zirconium or hafnium compounds have been reported. Bradley (71) in attempting to dissolve dialkylamine compounds, M(NR2)x> where M = Zr or Hf, and R = methyl, ethyl, or w-propyl, in carbon disulfide, found that a vigorous reaction occurred with formation of A, A -dialkylthiocarbamates, M(S2CNR2)4. The dimethyl derivatives are very insoluble and nonvolatile, suggesting that they might be polymeric, but the higher alkyl derivatives are soluble and monomeric. The ligand appears to be bidentate.

Bohme and Zinner (34), who prepared the methyl, ethyl, and benzyl derivatives. With iodine, the trisulfides give symmetrical liexasulfides. Feh6r and Kruse (66) prepared phenyl-hydrogen tri- and tetrasulfide and n-butyl-hydrogen tetrasulfide and studied their Raman spectra. The compounds are sensitive to bases, and salts are apparently unstable, although White (226) in 1918 reported a stable sodium salt of 2-naphthyl-hydrogen disulfide.
