摘　　要：聚异丁烯硫膦酸钙(简称硫膦酸钙)清净剂加热放出硫化氢气体,是其产生气味的原因。考察硫膦酸钙和其他添加剂复配时产生硫化氢的情况,结果发现硫膦酸钙和烷基苯磺酸钙、ZDDP复配时产生的硫化氢较多。考察后处理工艺对硫化氢放出数量的影响,结果发现加入后处理剂后,硫化氢放出量有不同程度的下降,其中采用后处理剂X的效果最好。考察合成硫膦酸钙时水解反应时间、钙化助促进剂种类等因素的影响,改进合成工艺,得到的硫膦酸钙清净剂性能满足要求,同时产品放出的硫化氢质量分数低于20μg/g,达到安全使用的要求。Hydrogen sulfide gas was emitted from heating up the calcium polyisobutylene thiophosphonate,which is the cause of its odor.The production of hydrogen sulfide when calcium sulphonate mixed with other additives was detected.It was found that more H2S was released when calcium polyisobutylene thiophosphonate was mixed with ZDDP and calcium alkyl benzene sulfonate.The influence of post-treatment process on the emission of hydrogen sulfide was investigated,and it was found that the emission of hydrogen sulfide decreased to different degrees after the addition of post-treatment agent,among which post-treatment agent X had the best effect.The effects of hydrolysis reaction time and calcification promoter type on the synthesis of calcium thiophosphonate were investigated.The improved synthetic process was helpful to satisfy the requirements of the performance of calcium thiophosphonate detergent.At the same time,the mass fraction of hydrogen sulfide released by the product was less than 20μg/g and met the requirements for safe use.
