5-甲基苯并三氮唑

5-甲基苯并三氮唑用途

【用途一】
用作铜的防锈剂
【用途二】
该品作为铜和铜合金缓蚀剂，与苯并三唑（BTA）类似，实际商品还包括4-甲基苯并三唑（[29878-31-7]）或者为两者的混合物，简称TTA。苯并三氮唑类缓蚀剂能与亚铜离子形成不溶性的稳定络合物，吸附在金属表面上，形成一层稳定的和惰性的保护膜，厚度仅5×10-7cm，但在各种介质中很稳定，从而使铜合金得到了保护。BTA在pH值为5.5-10范围内的缓蚀作用都限好，但在低pH值介质中，TTA的缓蚀作用比BTA强。其他三氮唑化合物，例如三氮唑和萘并三氮唑等对铜及铜合金也有缓蚀作用，但不如BTA和TTA。甲基苯并三唑也用于有机合成。

5-甲基苯并三氮唑制备

1.与苯并三唑的制法相仿，可由甲苯二胺重氮化、环合而得。一种较老的方法是由间甲苯胺重氮盐与对甲苯磺酰胺反应得到

2.将甲苯二胺重氮化，在乙酸中环化、再经减压蒸馏得到粗甲基苯并三唑，经重结晶、精制、干燥，即可制得较纯的甲基苯并三唑。还有以甲基邻苯二胺和亚硝酸乙基己酯为原料，以乙基己醇为溶剂，不经精馏即可制得较纯甲基苯并三唑的方法。
