ACTION OF THE HALOGENS^ ETC. 177 



lines passed over. These were filtered off, and heated with dilute 

 HCl. A dichlor product dissolves leaving a trichlor product un- 

 changed. The filtrate containing the dichlorquinoline was made alka- 

 line with ammonia, whereupon the base separated out. On recrystal- 

 lizing from alcohol, snow white needles melting at 80—81'' are 



obtained.

The trichlorparatoluquinoline, which was insoluble in dilute 



HCl, was recrystallized from alcohol. It is white and melts at 159.
