摘要

以天然脂肪醇为起始剂，在催化剂的作用下，进行乙氧基化反应，用气相色谱法分析了脂肪醇聚氧乙烯醚(AEO)产物的组成分布。研究结果表明，采用自制催化剂，可以得到分子量分布窄的脂肪醇聚氧乙烯醚。在120℃

0. 1~0. 3MPa的压力条件下，当环氧乙烷平均加和数为1. 6时，聚合产物中残留脂肪醇为15. 5%， AEO

1-3

的含量为76. 2%。

Abstract

Natural fatty alcohols were ethoxylated to synthesize fatty alcohol polyoxyethylene ethers in the presence of the catalyst prepared in our lab and the ethoxymer distributions were analyzed by gas chromatogram. The experimental results indicated that the ethoxylated oligomers showed very narrow distribution in the presence of the catalyst. In the case of average adduct number of ethylene oxide 1. 6

the reaction pressure 0. 1~0. 3MPa

the reaction temperature 120℃

the mixed fatty alcohol polyoxyethylene ether with only 15. 5 % of the free alcohol and 76. 2% of the main oligomers AEO

1-3

was obtained.
