Chlorination of Butyryl Chloride in the Liquid Phase

The photochlorination of butyryl chloride in the liquid phase at room temperature has been studied.The progress of the chlorination was followed, the mono- and dichloro products being identified and estimated by GLC as their methyl esters.The isomer distribution has been studied in detail at different stages of chlorination.The main compounds identified in the reaction mixture were substrate until 0.5 h, 3-chlorobutyryl chloride between 0.5 and 2.5 h, 3,4-dichlorobutyryl chloride between 2.5 and 7.5 h, 3,3-dichlorobutyryl chloride between 7.5 and 10.0 h and 4,4-dichlorobutyryl chloride after chlorination for 10.0 h.Polychloro compounds were, however, the main products towards the end of the process.
