对叔丁基邻苯二酚制备

(1)由邻苯二酚与叔丁醇反应而得在反应釜中依次投入二甲苯、邻苯二酚和磷酸，搅拌加热溶解，继续升温至二甲苯回流时，再慢慢滴加叔丁醇的二甲苯溶液，加完后继续搅拌2h，降温。然后将物料送至中和洗涤罐静置，分去磷酸，过滤后循环使用；二甲苯层用碳酸钠中和至pH值为5～6，用水洗涤，再进行减压蒸馏而得成品。需提纯时可采用石油醚重结晶。 (2)由邻苯二酚与异丁烯反应而得将磷酸、二甲苯、邻苯二酚加入反应釜，搅拌混合后加热至80～90℃。然后继续升温至105～110℃通入异丁烯。通足异丁烯后冷却至50～60℃，静置5～6h。将乳浊液用等体积的水冲稀，离心过滤，滤液用饱和氯化钠溶液洗至pH值6。加热蒸馏回收二甲苯，然后再减压蒸馏，收集170～173℃（1.33kPa）馏分，即为成品。 3. 由邻苯二酚与叔丁醇反应而得二甲苯、邻苯二酚和磷酸，搅拌加热溶解，继续升温至二甲苯回流时，滴加叔丁醇的二甲苯溶液，进行反应。经降温、静置，二甲苯层用碳酸钠中和，用水洗涤，再进行减压蒸馏而得成品。或者由邻苯二酚与异丁烯反应而得，将磷酸、二甲苯、邻苯二酚加入反应釜，升温至一定温度通入异丁烯。反应完毕后经离心过滤，滤液用饱和氯化钠溶液洗至ｐＨ值为6，蒸馏回收二甲苯，减压蒸馏，收集即可。
