详细合成路线

对苯二酚上游产品

对苯二酚下游产品

1.将苯胺、二氧化锰和硫酸按摩尔比为1∶3∶4加入反应釜内，加料时应在夹套中通冷冻水控制温度在10℃以下。搅拌下反应10h，反应温度逐渐升至25℃左右，生成苯醌。然后在反应物内通入水蒸气进行水蒸气蒸馏，蒸出的苯醌与水蒸气经部分冷凝后流入还原釜，再加入与苯醌的摩尔比为1∶0.7的铁粉，加热至90～100℃，搅拌下反应3～4h，还原反应的产物为对苯二酚。还原产物经过滤除去氧化铁渣后，进行减压脱水浓缩。然后加入焦亚硫酸钠、活性炭、锌粉，加热至沸腾进行脱色。趁热过滤后，滤液缓缓降温至30℃以下，对苯二酚以针状结晶析出，经离心脱水后，加入沸腾床于80℃下进行干燥，即得成品。

2.苯酚羟基化法　采用过氧化氢作羟基化剂，反应在催化量的无机强酸或二价铁盐或钴盐存在下进行。总反应式为：

3.二异丙苯氧化法　利用过氧化物进行氧化反应，制得氢醌。其反应式如下：

4.照相级氢醌的制法　是用活性炭对溶解于无盐水中而形成的氢醌溶液进行脱色处理，然后于5～10℃下重新结晶，经离心分离后置于非氧化气氛中干燥制成。
