p-Toluenesulfonic acid → 1-Pentene, 5,5,5-trichloro-2-methyl-

Participants

Reaction Steps

Then, to 732 g of 1,1,1-trichloro-4-methyl-4-pentanol was added 7.3 g of p-toluenesulfonic acid and the mixture was heated at 155°-160° C. for 1.5 hours, the byproduct water being azeotropically removed. The reaction mixture was as such distilled under a reduced pressure of 200 mmHg and the distillate was dried over sodium sulfate and fractionally distilled. By the above procedure was obtained 62 g of 1,1,1-trichloro-4-methyl-4-pentene as a fraction boiling at 73°-74° C. (20 mmHg), together with 536 g of 1,1,1-trichloro-4-methyl-3-pentene as a fraction boiling at 74°-77° C. (20 mmHg).
