吐温 60用途

聚氧乙烯山梨醇单硬脂酸酯是饱和脂肪酸硬脂酸(C18:0)的酯。聚氧乙烯山梨醇单硬脂酸酯可用作赋形剂,如表面活性剂、乳化剂、增溶剂、润湿剂等。药用辅料,或称药用辅料,是指除药物成分外,在制药过程中使用的其他化学物质。药用辅料一般是指药物制剂中的非活性成分,可以提高药物制剂的稳定性、溶解性和加工性。药用辅料也会影响联合给药药物的吸收、分布、代谢和消除(ADME)过程[1][2]。

吐温 60制备

1.将1 mol斯盘60投入反应釜中，加热熔化后开搅拌，加入催化剂量的氢氧化钠溶液。抽真空减压脱水，脱水完毕后用氮气置换釜中的空气，升温至140℃开始通入环氧乙烷4 mol进行缩合反应，缩合温度维持在160～180℃。通环氧乙烷到配比量后冷却，出料液打入中和釜，用冰醋酸中和至酸值2左右，然后用双氧水脱色，脱水，出料包装即为成品。

2.在甲醇钠(或乙醇钠)的催化下、130～170℃时，Span-60中通入一定量的环氧乙烷发生加成反应得产品。将330 kg乳化剂S-60加入反应釜中，加热熔化后，开搅拌加入催化剂量的氢氧化钠溶液。抽真空减压脱水，用氮气置换釜中的空气，升温至140℃后开始通环氧乙烷700 kg，控制反应温度在160～180℃。环氧乙烷通至配比量后，将料液打入中和釜，用冰醋酸调pH值至酸值2左右，最后用适量的双氧水脱色，冷却包装即为成品。
