主要用途編輯
1.用于制作環(huán)氧樹脂，雙酚A的催化劑，是日用化妝品冷燙精及脫毛劑的主要原料，也可用作合成PVC透明塑料和有機(jī)銻，有機(jī)錫的熱穩(wěn)定劑的基礎(chǔ)原料。其試劑產(chǎn)品是檢驗(yàn)鐵，鉬，銀，錫等金屬離子的靈敏試劑。選礦上為硫化銅及硫化鐵礦物的抑制劑。在石油化學(xué)工業(yè)和鐵路部門，用于設(shè)備及鐵軌的清洗除銹。
TGA既具羥酸的反應(yīng)特征，又具巰基的反應(yīng)特征，其中最重要的反應(yīng)是與二硫化物之間的反應(yīng)。特別是堿性條件下與頭發(fā)中的胱氨酸反應(yīng)，切斷胱氨酸的（-S-S-）鍵，生成易于卷曲的半胱氨酸。是生產(chǎn)硫甲丙脯（卡普托利）、生物素、硫鋅酸、二硫基丁二酸鈉等醫(yī)藥品的中間體，也是合成半胱氨酸、荷爾蒙化劑、工業(yè)消毒劑及合成硫酸的重要原料。
2.其銨鹽和鈉鹽主要用作卷發(fā)劑、鈣鹽可用做脫毛劑、聚氯乙烯低毒或無(wú)毒穩(wěn)定劑、聚合反應(yīng)的引發(fā)劑、加速劑及鏈轉(zhuǎn)移劑、金屬表面處理劑。此外，巰基乙酸是檢定鐵、鉬、鋁、錫等的敏感試劑；也可作為聚丙烯加工成型時(shí)的結(jié)晶成核劑以及涂料、纖維的改性劑、毛毯速理劑。聚氯乙烯、橡膠的穩(wěn)定劑原料、冷燙發(fā)用藥劑、醫(yī)藥中間體。
3.用作光度法測(cè)定鉬、錸和鐵等的顯色劑，并用作配合掩蔽劑。其鹽還用于配制卷發(fā)冷燙劑和脫毛劑。
4.脫毛劑。巰基乙酸鹽在較強(qiáng)堿性下，涂在皮膚上能進(jìn)行快速脫毛。巰基乙酸可用于美容、臨床手術(shù)前及動(dòng)物實(shí)驗(yàn)時(shí)的脫毛。最常用的是巰基乙酸的鈣鹽，最適宜ph值為11.5～12。最低有效含量為：5%巰基乙酸，7%鈣鹽。
5.金屬表面處理劑。添加極少量的巰基乙酸即能改進(jìn)金屬清洗劑和浸漬液的清洗效果，并能抑制被處理金屬表面的腐蝕，故常用于金屬的精密加工中的防銹劑。這種效果在很廣泛的ph值范圍內(nèi)均很顯著。含巰基乙酸的多組分清洗-防銹液可用于汽車?yán)鋮s系統(tǒng)的清洗，ph值為10.6。巰基乙酸的十六烷基酯可拋光或清洗銀制品，不會(huì)使銀器表面失去光澤。
6.聚氧乙烯低毒或無(wú)毒穩(wěn)定劑。巰基乙酸辛錫酸、甲錫酯、辛酯、2-乙基己酯、甲氧基丁酯、乙氧基乙酯等具有低毒與無(wú)毒性，經(jīng)美國(guó)食品與藥物管理局批準(zhǔn)，上述酯類可作為低毒無(wú)毒穩(wěn)定劑。可用于聚氯乙烯上水管道、水泵等產(chǎn)品的加工，食品包裝，食品加工廠的設(shè)備管道，亦可用于化妝品廠及制藥廠，且這類穩(wěn)定劑使產(chǎn)品透明性和熱穩(wěn)定性均有提高。此外，本品是檢定鐵、鉬、鉛、錫等的敏感試劑。還可用作纖維改性劑、毛毯整理劑。
7.用作測(cè)定鐵的試劑及穩(wěn)定劑，用于藥水、燙發(fā)水制造等。
8.作為石油勘探緩蝕劑。巰基乙酸可以一種嗅鹽完井液的優(yōu)良緩蝕劑，在石油勘探鉆探高壓井時(shí)，為了保護(hù)油氣層，減少對(duì)地層的傷害，需使用溴化物的無(wú)固相完井液，這些鹽的濃溶液具有很強(qiáng)的腐蝕性，并且隨溫度的升高腐蝕性加劇。在高溫下抑制鹽水腐蝕的緩蝕劑只有含硫化合物，巰基乙酸鹽在一定溫度下與金屬發(fā)生化學(xué)反應(yīng)，形成一層致密的FeS保護(hù)膜，起到了緩蝕作用。
