Abstract
The present invention discloses processes for producing a thiol compound or a sulfide compound from an olefin compound. Diphenylamine or a phenol compound can be used to increase the rate of conversion of the olefin compound to the thiol compound or the sulfide compound.
Claims22
A process for producing a thiol compound, the process comprising:
- i) contacting:
- a) an olefin compound;
- b) H2S;
- c) diphenylamine and/or a phenol compound;
- and
- d) a photoinitiator and/or a free radical initiator;
- and
- ii) forming the thiol compound.

A process for producing a sulfide compound, the process comprising:
- i) contacting:
- a) an olefin compound;
- b) a mercaptan compound;
- and
- c) diphenylamine and/or a phenol compound;
- and
- ii) forming the sulfide compound;
- wherein an amount of diphenylamine and/or the phenol compound is in a range from about 0.05 wt. % to about 5 wt. %, based on the weight of the olefin compound.
5 more elements
A process for producing a sulfide compound, the process comprising:
- i) contacting:
- a) an olefin compound;
- b) a mercaptan compound;
- and
- c) diphenylamine and/or a phenol compound;
- and
- ii) forming the sulfide compound;
- wherein a molar percent conversion of the olefin compound is at least about 90%.
