主要用途编辑
1.用于制作环氧树脂,双酚A的催化剂,是日用化妆品冷烫精及脱毛剂的主要原料,也可用作合成PVC透明塑料和有机锑,有机锡的热稳定剂的基础原料。其试剂产品是检验铁,钼,银,锡等金属离子的灵敏试剂。选矿上为硫化铜及硫化铁矿物的抑制剂。在石油化学工业和铁路部门,用于设备及铁轨的清洗除锈。
TGA既具羟酸的反应特征,又具巯基的反应特征,其中最重要的反应是与二硫化物之间的反应。特别是碱性条件下与头发中的胱氨酸反应,切断胱氨酸的(-S-S-)键,生成易于卷曲的半胱氨酸。是生产硫甲丙脯(卡普托利)、生物素、硫锌酸、二硫基丁二酸钠等医药品的中间体,也是合成半胱氨酸、荷尔蒙化剂、工业消毒剂及合成硫酸的重要原料。
2.其铵盐和钠盐主要用作卷发剂、钙盐可用做脱毛剂、聚氯乙烯低毒或无毒稳定剂、聚合反应的引发剂、加速剂及链转移剂、金属表面处理剂。此外,巯基乙酸是检定铁、钼、铝、锡等的敏感试剂;也可作为聚丙烯加工成型时的结晶成核剂以及涂料、纤维的改性剂、毛毯速理剂。聚氯乙烯、橡胶的稳定剂原料、冷烫发用药剂、医药中间体。
3.用作光度法测定钼、铼和铁等的显色剂,并用作配合掩蔽剂。其盐还用于配制卷发冷烫剂和脱毛剂。
4.脱毛剂。巯基乙酸盐在较强碱性下,涂在皮肤上能进行快速脱毛。巯基乙酸可用于美容、临床手术前及动物实验时的脱毛。最常用的是巯基乙酸的钙盐,最适宜ph值为11.5~12。最低有效含量为:5%巯基乙酸,7%钙盐。
5.金属表面处理剂。添加极少量的巯基乙酸即能改进金属清洗剂和浸渍液的清洗效果,并能抑制被处理金属表面的腐蚀,故常用于金属的精密加工中的防锈剂。这种效果在很广泛的ph值范围内均很显著。含巯基乙酸的多组分清洗-防锈液可用于汽车冷却系统的清洗,ph值为10.6。巯基乙酸的十六烷基酯可抛光或清洗银制品,不会使银器表面失去光泽。
6.聚氧乙烯低毒或无毒稳定剂。巯基乙酸辛锡酸、甲锡酯、辛酯、2-乙基己酯、甲氧基丁酯、乙氧基乙酯等具有低毒与无毒性,经美国食品与药物管理局批准,上述酯类可作为低毒无毒稳定剂。可用于聚氯乙烯上水管道、水泵等产品的加工,食品包装,食品加工厂的设备管道,亦可用于化妆品厂及制药厂,且这类稳定剂使产品透明性和热稳定性均有提高。此外,本品是检定铁、钼、铅、锡等的敏感试剂。还可用作纤维改性剂、毛毯整理剂。
7.用作测定铁的试剂及稳定剂,用于药水、烫发水制造等。
8.作为石油勘探缓蚀剂。巯基乙酸可以一种嗅盐完井液的优良缓蚀剂,在石油勘探钻探高压井时,为了保护油气层,减少对地层的伤害,需使用溴化物的无固相完井液,这些盐的浓溶液具有很强的腐蚀性,并且随温度的升高腐蚀性加剧。在高温下抑制盐水腐蚀的缓蚀剂只有含硫化合物,巯基乙酸盐在一定温度下与金属发生化学反应,形成一层致密的FeS保护膜,起到了缓蚀作用。
