本文研究了活性炭对磷钼钨杂多酸的固载化方法 ,结果发现使用蒸发法进行固载 ,当活性炭与磷钼钨杂多酸的质量比为 1∶0 75时 ,所得固载型杂多酸的催化效果最好。利用所制备的活性炭固载杂多酸型催化剂探讨了醋酸与各种一元脂肪醇的酯化反应 ,发现该催化剂对醋酸脂肪醇酯的合成均具有较好的催化效果 ,并且重复使用 4次 ,催化活性仍较高
In this paper, the immobilization of activated carbon on phosphomolybdic tungsten heteropolyacid was studied. It was found that the immobilized heteropolyacid was immobilized by evaporation. When the mass ratio of activated carbon to heteropolyphosphoric acid was 1: 0, 75, The best catalytic effect of polyacid. The prepared catalyst was used to immobilize heteropolyacid catalysts to investigate the esterification reaction of acetic acid with various monohydric aliphatic alcohols. It was found that the catalyst had a good catalytic effect on the synthesis of fatty alcohol esters of acetic acid and was reused for 4 times, Catalytic activity is still high
