Abstract:
The optimum cond it ion of the synthesis of 1, 1, 1, 3, 3-pentachloropropane is studied in this paper. 1, 1, 1, 3, 3-pentachloropropane is prepared by rad ical addition react ing carbon tetrach loride w ith v inyl chloride in the presence o f cuprous chloride. The product is determ ined byNMR, GC-MS, GC, etc. . Through the research of influencing factors, the opt imum condition o f the synthet ic process of 1, 1, 1, 3, 3-pentach loropropane is obtained as fo llow s: the dosage o f solvent acetontrile is 10% ~ 20% of total qua lity of react ion compounds, n ( CC l4 ) Bn ( VnC l) = 1B0. 3~ 0. 4, the react ion temperature is 110~ 125 e , the react ion pressure is 0. 5~ 1. 0Mpa, the reaction time is 5~ 8 h, the ca-t alyst cuprous chloride is 1. 5% ~ 3. 5% of the quality of viny l chloride. The triethaolam ine is se lected to use as the catalyst promoter, and its dosage is equa lw ith cuprous ch loride. The yie ld of 1, 1, 1, 3, 3-pentach loropropane can be reached 72% and the purity o f product is 98%.
