Claim 0:
1. A process for purifying an alkyl sulfide composition, the process comprising:
(i) contacting the alkyl sulfide composition comprising carbon disulfide (CS2) and at least 80 wt. % of an alkyl sulfide with water to form an aqueous alkyl sulfide composition;
(ii) contacting the aqueous alkyl sulfide composition with a mixed-metal catalyst at
a temperature in a range of from about 100° C. to about 300° C.,
a pressure in a range of from about 5 psig to about 300 psig,
a molar ratio of water to CS2 in a range of from about 10:1 to about 100:1, and
a weight hourly space velocity (WHSV) in a range of from about 0.05 to about 5; and

(iii) hydrolyzing a least a portion of the CS2 to form a purified alkyl sulfide product stream.
