Abstract

Abstract: A layered double hydroxide (LDH) material whose structure was similar to that of hydrotalcite was synthesized by co-precipitation method.The prepared catalyst modified with arachidic acid was significantly different from the one before modification according to the characterization by FT-IR and N₂ adsorption.The modified catalyst was applied in ethoxylation of butyl acetate with stationary bed reactor.The results show that,the conversion of butyl acetate is 24.7%,the selectivities of 1-EBAC and 2-EBAC are 17.6% and 12.8%,respectively.The modified catalyst shows distinctly enhanced reactivity.The content of target product is improved,and the distribution of the product is narrower as well.

Key words: ethylene glycol butyl ether acetate, stationary bed, reaction temperature, WHSV
