化合物简介
Phenyl salicylate, or salol, is a chemical substance, introduced in 1886 by Marceli Nencki of Basel. It can be created by heating salicylic acid with phenol. Once used in sunscreens, phenyl salicylate is now used in the manufacture of some polymers, lacquers, adhesives, waxes and polishes. It is also used frequently in school laboratory demonstrations on how cooling rates affect crystal size in igneous rocks.

生产方法
1.将28kg工业苯酚、40kg工业水杨酸投入干燥的反应釜内,加热熔融,严格控制温度(130
±2)℃。搅拌下缓缓滴入三氯化磷16kg进行反应,加毕,仍保持(130
±2)℃,搅拌4h。排尽反应生成的氯化氢后,趁热用两倍的65℃热水洗涤,静置40min,分去水层后,再洗涤1次。用5%的碳酸氢钠溶液中和至pH为8,再用65℃的热水洗至pH值为7。静置,分去水层,在油层中加入约1倍的蒸馏水搅拌均匀、冷却、结晶、活性炭脱色,即得成品。
