摘要
研究了五种杂多酸(盐)在苯酚羟化反应中的催化活性。在考查的催化剂中 ,H4SiW12O40 和K4H2[SiW11Co(H2O)O39]催化效果最好 ,苯酚的转化率分别达49.3 %和40.3% ,邻苯二酚的选择性分别达73.3%和88.2 % 。
The catalytic activities of polyoxometalates for hydroxylation of phenol have been investigated.H4SiW12 and K4H2[SiW11Co(H2O)O39] are found to be Superior catalysts for the reaction.The conversion of pherol reaches 49.3% and 40.3%,respectively,and the selectivity of hydroquinone reaches 73.3% and 88.2%,respectively.
