| 摘 要： | 研究了采用固体酸为催化剂,以氢醌和甲醇为原料,苯醌为助剂,合成氢醌单甲醚.发现添加助剂苯醌,可大大提高氢醌转化率和氢醌单甲醚收率.在重量比氢醌/苯醌为6:1,氢醌/催化剂为1.5:1的条件下,氢醌转化率87%,氢醌单甲醚摩尔收率98%.反应过程中不生成氢醌二甲醚.固体酸催化剂可反复多次使用.

| Abstract: | The synthesis of hydroquinone monomethyl ether from hydroquinone and methanol using solid acid as cata-lyst and quinone as promoter was investigated. It was found that the conversion of hydroquinone is 87% and the mole yield of hydroquinone monomethyl ether is 98% when hrdroquinone/quinone (g/g) is 6/1 and hydro-quinone/catalyst(g/g) is 1. 5/1.No hydroquinone dimethyl ether (HQDME) produced during the reaction. The catalyst can be used many times repeatedly. |
