ABSTRACT:
Synthesis of mercaptans by the photochemical reaction of an olefin with hydrogen sulphide in the presence of an initiator constituted by benzophenone, thiobenzophenone or a mixture of the two, preferably accompanied by an organic compound of an element of Group VA of the Periodic Classification. These initiators can carry substituents on either or both of the two benzene rings. The light utilized can have a wavelength of 300 to 600 nm. The process allows various mercaptans to be obtained with good yields.
