摘要： Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an alkanolamine and converting the carbon disulfide to a higher boiling point product, thereby reducing or eliminating carbon disulfide from the product stream. Subsequent removal of the higher boiling point product via distillation can lead to a purified sulfide stream with high purity.
