钛胶是邻二甲苯制苯酐等多种物质的催化剂载体。由于应用场合的不同,钛胶的制法可分为硫酸盐法,氯化物法和钛脂法。氯化物法水解产物即使在很低的温度下灼烧,也难得锐钛型(Anatase)钛胶(苯酐催化剂要求锐钛型钛胶含量90%以上);钛酯法,易得需要结构的钛胶,但成本昂贵,成批生产有困难,因此多用硫酸盐法。 Titanium is ortho-xylene benzene anhydride and other substances in the catalyst carrier. Due to the different applications, titanium rubber system can be divided into sulfate method, chloride method and titanium fat method. Chloride hydrolysis even at a very low temperature burning, but also rare Anatase Titanic (phthalic anhydride catalyst requires anatase titanium dioxide content of more than 90%); titanium ester method, easy to get the need for the structure of titanium Plastic, but the cost is expensive, batch production is difficult, so use sulfate method.
