【摘要】 对烷氧基金属化合物和月桂酸皂类化合物催化月桂醇乙氧基化窄分布作用进行了研究，用高效液相色谱分析了乙氧基化产物的分布状态。结果表明：烷氧基金属和皂类化合物具有一定的脂肪醇乙氧基化催化活性，同用ＮａＯＨ催化得到的产物相比，具有较好的窄分布效果。皂类化合物中以月桂酸钡催化剂窄分布效果较为显著。烷氧基金属化合物中，随着烷基链的增长窄分布催化作用逐渐增强更多还原

【Abstract】 The paper probes into the catalyzing effects of oxyalkyl metal compounds and lauric soap compounds on the narrow distribution with HPLC method,analyses the distribution status of ethoxylates.The results show that both oxyalkyl metal compounds and soap compounds have certain catalyzing activities in fatty alcohol ethoxylation and that the distribution range of above products is much narrower than that of products catalyzed with NaOH.Among soap compounds,barium lauric shows the narrowest effects,and as for oxyalkyl metal compounds the narrow distribution effect seems to increase gradually along with the increase of alkyl chains.更多还原
