一种非离子表面活性剂合成工艺的研究
Synthesis of a kind of nonionic surfactant with a modified catalyst
摘要
Abstract
A catalyst containing Mg-Al composite with both acidic and basic activities and structure similar to that of hydrotalcite was prepared by co-precipitation method under weak alkaline condition using magnesium nitrate crystal and aluminum nitrate crystal as starting materials. The prepared catalyst,after modified with arachidic acid was tested and characterized by X-ray diffraction (XRD),NH 3-temperature programmed desorption (NH 3-TPD)and CO 2-TPD. Then the modified catalyst was applied in ethoxylation of butyl acetate with a fixed bed reactor. Results showed that the prepared and modified catalyst displays conspicuous enhancement of activity for the conversion. The content of targeted products,ethylene glycol butyl ether acetate 1-EBAC and 2-EBAC is higher as well as their carbon number distribution is narrower.关键词
