7-Trifiuoromethyiquinoline.-Upon redistillation at atmospheric pressure, the fraction (10 g., 12.7%) distilling between 205-218'consisted chiefly of 5-trifluoromethylquinoline; and the fraction (34 g., 43%) distilling over at 218-225'was largely 7-trifluoromethylquinoline. When the latter, higher-boiling fraction was cooled, crystallization set in. Recrystallization from 60% ethanol gave a product melting at 66-68', Redistillation of these crystals gave 7- ...
