硫丹(endosulfan)是由亚硫酰氯与六氯环戊二烯和顺丁烯二醇-1,4的加成产物反应而得的非碱性杀虫剂,是α、β两种立体异构体的混合物。工业粗品中α、β异构体的比例为7∶3。它对日光稳定,但能被酒精和二氧化硫缓慢水解。硫丹不溶于水,20℃在丙酮中的溶解度为33%,氯仿中为50%,甲醇中为11%,煤油中为20%。在正常条件下贮藏是稳定的,但能被酸和碱所水解。 Endosulfan is a non-basic insecticide derived from the reaction of thionyl chloride with the addition product of hexachlorocyclopentadiene and maleate-1,4, which is a mixture of α, β two stereoisomers Body mixture. Industrial crude α, β isomer ratio of 7: 3. It is stable to sunlight but can be slowly hydrolyzed by alcohol and sulfur dioxide. Endosulfan is insoluble in water, 33% in acetone at 20 ° C, 50% in chloroform, 11% in methanol and 20% in kerosene. Stored under normal conditions is stable, but can be acid and alkali hydrolysis.
