Abstract
Mercaptans are prepared by reacting an organic chloride or bromide with a mixture of H.sub.2 S and ammonia or an amine at a temperature of 0.degree. to 175.degree. C. under autogenous pressure. The reaction can be carried out in the presence of a polar solvent. For example, 3-chloropropyltrimethoxysilane is mixed with H.sub.2 S and ammonia in methanol and heated in a closed container at 100.degree. C. for 18 hours.
