A series of antimony mercaptide compounds which formula are Sb 〓 and Sb S (CH〓〓COOR 〓(R represents an alkyl or aryl, aralkyl, n=0～2) have been synthesized. A new synthetic method has been invented to solve the defect of abroad patent method which has complex technological conditions and singleness intermediate compounds. A new catalyst QL-1 and preactivated antimony trioxide and other means have been used to avoid neutralizing, washing, separating and other procedures of intermediate and simplifing process flow at the same time. According to this new technique, a series of antimony mercaptides and their intermediate products have been synthesized with high yield.
