摘要/Abstract

摘要： 通过共沉淀法合成水滑石类LDH复合氧化物,经过花生酸改性后,发现其在FT-IR、N₂吸附的表征中与改性前相比有显著差别;将其作为催化剂在固定床反应器上进行醋酸丁酯的乙氧基化反应,醋酸丁酯的转化率为24.7%,产物1-EBAC和2-EBAC的选择性分别为17.6%和12.8%。结果表明反应活性明显提高,目标产物含量显著增大,产品分布变窄。

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
