在常压和较低的温度下,系统地研究了均相、非均相和固载型杂多酸(盐)催化剂在合成 DOP 中的催化作用,实验表明在合成 DOP 的酯化反应中,杂多酸(盐)具有很高的催化活性和选择性,首次将不饱和系列杂多酸催化剂应用于酯化反应。催化剂连续使用12次未见活性明显降低,DOP 催化属体型和表型反应的叠加。 Under normal pressure and low temperature, the catalytic effect of heteropoly acid (HOMO) catalysts on the synthesis of DOP has been investigated systematically. The experiments show that in the esterification of DOP, Heteropolyacid (salt) has high catalytic activity and selectivity, the first for the unsaturated series of heteropolyacid catalyst used in esterification. Continuous use of the catalyst 12 times no activity was significantly reduced, DOP catalyst body type and phenotype reaction superposition.
