1.用于处理工业循环水，起杀菌灭藻作用.是一种广普的杀菌防腐剂，能有效杀灭藻类、 细菌和真菌。该活性单剂可广泛用于工业冷却水、油田回罐水、造纸行业、管道、涂料、油漆、橡胶以及化妆品、感光胶片及洗涤用品等工业。有效用量少，无毒无污染，极易混合在各类配方中， PH 使用范围广，稀释使用浓度后，很容易被生物降解为无毒无污染物质
2.异噻唑啉酮是一种广谱、高效、低毒、非氧化性杀菌剂，运用于油田、造纸、农药、切削油、皮革、油墨、染料、制革等行业。异噻唑啉酮2类产品作黏泥剥离剂时，投加浓度150～300mg/L；作杀菌剂时，每隔3～7天投加一次，投加剂量80～100mg/L。能与氯气等氧化型杀菌剂同时使用，不能用于含硫化物的冷却水系统。异噻唑啉酮与季铵盐复合使用效果较佳。异噻唑啉酮做工业杀菌防霉剂使用时，一般浓度为0.05%～0.4%。
3.能很好地穿过黏泥表层而杀灭黏泥中的菌藻，能阻止冷却水系统的黏泥生成。可广泛用于造纸厂白水、冷却水、油田注水、金属加工油、乳胶、纤维及涂料等防霉。

1.主要由5-氯-2-甲基-4- 异噻唑啉-3-酮 （CMI）和2-甲基-4-异噻唑啉-3- 酮（MI）组成。
2.二硫代二丙酸二甲酯与甲胺进行氨解反应生成犖，N,N ′ -二甲基二硫代二丙酰胺，然后在乙酸乙酯溶液中通氯气而制得，反应式如下：
将二硫代二丙酸二甲酯加入反应釜，往夹套通冷冻盐水，开动搅拌器，使釜内温度降至0℃，慢慢加入25%甲胺溶液及0.3%稀盐酸，于约5℃反应3h。反应完毕，将反应物放入结晶釜，于室温下放置，使析出N，N ′- 二甲基二硫代二丙酰胺的白色结晶。离心过滤，用少量水洗结晶，然后送入干燥箱于108～110℃烘干。将干燥好的N， 犖N′ -二甲基二硫代二丙酰胺及无水乙酸乙酯加入反应釜，开动搅拌器，于0℃下通入预定量的氯气反应约1h，升至室温，离心过滤，用少量乙酸乙酯洗涤，真空干燥，得（Ⅰ）与 （Ⅱ）的混合物盐酸盐，母液及洗涤液合并，蒸馏塔回收乙酸乙酯。产品中两个活性组分的比例对产品质量影响很大。活性组分CMIO和 MIO可以通过N， 犖N′ -二甲基-3，3- 二硫二丙酰胺氯环化反应而制得。只有当它们质量比达到 CMIO∶MIO＝3∶1时，商品杀菌剂才具有最高的效能。
