稀土异羟肟酸盐催化合成邻苯二甲酸二甲酯的研究

CATALYTIC SYNTHESIS OF DIMETHYL PHTHALATE WITH RARE EARTH SALTS OF OXALOHYDROXAMIC ACID(RE-OXHA)

用ＲＥ－ＯＸＨＡ作催化剂合成邻苯二甲酸二甲酯，对催化剂的种类和数量以及反应温度和时间作了讨论。

This paper reports the study on RE-OXHA used. in the esterification of phthalic anhydride and rnethyl alcohol. The quantity and sort of catalyst,temperature and time of reaction are discussed.The results of the study indicate that the catalyst is good.
