摘　　要：由丙烯酸甲酯与碳酸氢钠、多硫化钠常压反应,蒸馏产物再与甲胺胺解,最后经二氯化砜氯环化得到Kathon CG的有效组分:2-甲基-4-异噻唑啉-3-酮和5-氯-2-甲基-4-异噻唑啉-3-酮。Kathon CG was obtained by methyl acrylate reacting atmosperic pressure, with sodium bicarbonate and sodium polysulfide under followed by amonolysis of methylamine and chloro-eyclization of sulfone chloride. Its ettective components are 2-methyl-4-isothiazolingl-3-ketone and 5-chloro-2-methyl-4-isothiazolingl-3-ketone。
