| Abstract: | The technological condition for synthesis of AEO3 using barium system catalyst were optimized in this paper. The optimization reaction condition was as follows:reaction temperature 150～180℃,catalyst concentration 0.8%～1.2%. The apparent energy for ethoxylation of lauryl alcohol was 61.3 kJ/mol. The residual alcohol content of ethoxylation product as using barium system catalyst is lower than using KOH catalyst, and barium catalysts give rise to a narrowrange molecular weight distribution of ethoxylation oligomers, compared with the potassium catalysts. |
