Abstract
Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an aqueous solution comprising a mercaptide to form a mixture, or by contacting the product stream with an aqueous solution comprising a mercaptan and a base to form a mixture. An aqueous layer is removed from the mixture, resulting in a high purity sulfide stream with significantly less carbon disulfide.
