苯酚乙氧基化反应的工艺研究

Study on the Ethoxylation of Phenol

研究用乙酸钙为催化剂的苯酚乙氧基化反应 ,着重考察了催化剂用量、反应压力等因素对产物相对分子质量分布的影响。与传统催化剂氢氧化钠相比 ,用乙酸钙为催化剂 ,其反应的相对选择性指标Q值提高了 60 % 。

The ethoxylation of phenol using calcium acetate as catalyst was reported in this article, focusing on the study of the influence of the pressure and the catalyst quantity on the product molecular weight distribution. In comparison with the process catalyzed by sodium hydroxide, the relative selectivity Q of this new ethoxylation process increased by about 60%, and the product had a narrower molecular weight distribution.
