Abstract
Aliphatic or cycloaliphatic mercaptans are prepared by reacting aliphatic or cycloaliphatic olefines with hydrogen sulphide in the presence of a catalyst comprising a complex derivative of boron-trifluoride with a saturated aliphatic or cycloaliphatic carboxylic acid. The catalyst is generally prepared by mixing equimolar amounts of the two components but, if desired, an excess of the acid may be used. The preferred acids contain up to 9 carbon atoms, such as formic, acetic, propionic, butyric and hexahydrobenzoic acids. The catalyst may be used in amounts of from 1-30% by weight of the olefine. Reaction is suitably effected at or slightly below atmospheric temperature and, if desired, under elevated pressure. The reagents are preferably anhydrous. The process may be effected continuously. In an example di- or tri-isobutene or propylene tetramer is reacted with H2S at 0-5 DEG C., using an acetic acid-BF3 complex as catalyst. Other specified olefines are ethylene, propylene, isobutene, cyclohexene and octenes, and dodecenes generally.
