摘要
以丙二酸二异丙酯、二硫化碳、氢氧化钠和二氯乙烷为原料,采用氯化物相转移催化法合成稻瘟灵,收率≥90%,纯度≥95%。生产成本大幅降低,经济效益显著。
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.
