丙烯醛氧化制丙烯酸的改性杂多酸催化剂研制

STUDY ON MODIFIED HETEROPOLY ACID AS CATALYST FOR OXIDATION OF ACROLEIN TO ACRYLIC ACID

由丙烯两步氧化法生产丙烯酸的工艺中 ,主要问题在于找到选择性及转化率较好的 ,污染较小的催化剂。本文论述了 P

In oxidation of acrolein to acrylic acid, modified, PMo heteropoly acids were used as catalyst, which have higher selectivity and conversion less pollution. And the effects of modified PMo heteropoly acid on catalytic activity have also been investigated.
