4-phenoxyphenol production methodThere are many preparation methods of 4-hydroxydiphenyl ether, two of which are low in raw material cost and simple in process. Hydroquinone and bromobenzene react with hydroquinone as raw materials, add dimethyl sulfoxide solvent and 96% potassium hydroxide solution, and at the same time pass in nitrogen, while heating to 140 ºC under stirring, slowly add bromobenzene solution dropwise , In (145
The reaction was carried out at a temperature of ±5) for 8 hours; after the reaction was completed, the aqueous phase was acidified with hydrochloric acid, and crystals were precipitated. The yield was 88%~89%. P-Chlorophenol method Add 235g (2.50mol) phenol, 42.1g (0.75mol) sodium hydroxide and 150mL toluene to a 500mL three-necked flask equipped with a thermometer, a water trap and a magnetic stirrer, and heat to separate water. After the solvent was removed, 1.75g copper salt was added as a catalyst, 64.3g (0.50 mol) p-chlorophenol was added dropwise, and the reaction was carried out at 175ºC for 8h. After the phenol is recovered, it is acidified with dilute hydrochloric acid. Extract with ether and wash with water. After drying, it is distilled to collect the 145~152ºC(800Pa) fraction to obtain 60g of the product, with a yield of 64%, m.p. 83~84ºC (literature value m.p. 85~86ºC).4-phenoxyphenol useUsed in the synthesis of high-efficiency, low-toxicity pesticides dioxycarb and cyprofen.
