Abstract

Mercaptans are prepared from oxygen containing organic compounds which are acids, alcohols, esters, ethers, aldehydes and ketones, by reaction with sulphur and hydrogen or a sulphur donor if necessary in the presence of hydrogen, using rhenium heptasulphide as catalyst. The reaction is preferably carried out under pressure with an excess of sulphur and hydrogen at a temperature of 200 to 300 DEG C. With acids the preferred temperature is 250 to 270 DEG C. and with alcohols 200 to 240 DEG C. The sulphur donor may be hydrogen sulphide, carbon disulphide, calcium sulphide or ammonium sulphide. Examples describe the preparation of mercaptans from caproic, caprylic, capric, lauric, myristic, palmitic, stearic, oleic and adipic acids, ethanol, heptanol, octanol, a -methylbutyraldehyde and methylisobutylketone. The 2.4 dinitro (alkylthio) benzene derivatives are prepared by reaction of the mercaptan with 2,4-dinitrochlorobenzene, and the alkyl (2,4-dinitrophenyl) sulphone derivatives are prepared by oxidation of the product. Specification 574,936 is referred to.
