isoprothiolane; phase-transfer-catalysis; chloride
摘  要:
Isoprothiolane was synthesized by diisopropyl malonate and carbon disulfide and NaOH and dichloroethane as material,with chloride as a phase-transfer-catalysis,in yield over 90% and the purification of product is higher than 95%. The production cost was considerably reduced,its economic efficiency has greatly improved.
