用于乙氧基化反应的酸性催化剂性能研究

Performance study of acid catalysts for ethoxylation reaction

在C_(12-14)脂肪醇的乙氧基化反应中,系统地研究了不同种类酸性催化剂(Lewis酸性催化剂SnCl_(4)与Mg(ClO_(4))_(2),Bronsted酸性催化剂H_(3)O_(40)PW_(12)·xH_(2)O,以及实验室自制均相酸性催化剂NAE-03)的催化性能。研究表明,采用实验室自制酸性均相催化剂NAE-03,可以得到高EO加合数,二噁烷含量低,应用性能好的脂肪醇聚氧乙烯醚。

The catalytic performance of different types of acidic catalysts(Lewis acidic catalyst SnCl_(4) with Mg(ClO_(4))_(2),Bronsted acidic catalyst H_(3)O_(40)PW_(12)·xH_(2)O,and laboratory homogeneous acidic catalyst NAE-03)was systematically investigated in the ethoxylation reaction of C_(12-14) fatty alcohols.It was shown that the laboratory homogeneous acidic homogeneous catalyst NAE-03 was used to obtain fatty alcohol polyoxyethylene ethers with high EO addition number,low dioxane content and good application performance.
