氯化歧化松香基铜盐的合成与杀菌活性研究

Bactericidal Activity of Synthetic Chlorinated Gum Rosin and Copper Salt

以歧化松香为原料,经氯化和铜盐化反应,合成目标产物氯化歧化松香基铜盐,探求反应的最佳工艺条件为:反应物摩尔比为歧化松香:二氯化砜=1:4,氯化歧化松香:氢氧化铜=3:1,催化剂用量为20mL,反应时间4h,反应温度80℃,并研究了所得产品的杀菌性能。

Chlorinated gum rosin and copper salt was synthesized with gum rosin,chlorosulfuric acid and cupric hydroxide.The best technological conditions were explored∶gum rosin：chlorosulfuric acid=1∶4（mol）,chlorinated gum rosin∶cupric hydroxide=3∶1,the dosage of catalyst was 20mL,with 80℃ reaction 5h.The bactericidal activity of last product was analyzed.
