合成脂肪酸生产过程中对氧化蜡进行热处理,能大大降低硫酸、纯碱消耗,从而降低副产芒硝的生成量。同时,脂肪酸的酯价和二元酸、酮酸含量也得到了改善。在氧化蜡热处理过程中,催化剂对酯水解的程度影响很大。研究了许多碱性和 Heat treatment of the oxidized wax during the production of synthetic fatty acids can greatly reduce the consumption of sulfuric acid and soda ash, thereby reducing the generation of by-products mirabilite. In the meantime, the ester and fatty acid contents of dibasic acids and keto acids have also been improved. In the oxidative wax heat treatment process, the degree of influence of the catalyst on the ester hydrolysis has a great impact. Has studied many alkaline and
