摘要：

The flash-induced photolysis of 4-chlorophenol in water has been studied by high performance liquid chromatography. The primary photoproduct is confirmed as being p-benzoquinone. The role of molecular oxygen in the photochemistry has been investigated and we conclude that it is not involved in the formation of the p-benzoquinone although it does appear to protect the primary photoproduct from secondary photolysis. A photolysis mechanism based on the initial formation of a radical cation is proposed.
