실험 절차

Summarizing Example 1, starting with fifty grams of a mixture rich in 3,4,5-trichloro-2-trichloromethyl pyridine, the analysis of which is set forth in Table One, and which contained 3% by weight ferric chloride, its chlorination with 70 grams per hour of chlorine, sparged into a 250 ml glass reactor at 200° C. for 5 hours, resulted in a product the analysis of which is set forth in Table One. As will be noted, a molar yield in excess of 65% of 3,4,5,6-tetrachloro-2-trichloromethyl pyridine based on 3,4,5-trichloro-2-trichloromethyl pyridine conversion was obtained.
