Abstract

PURPOSE: To obtain the titled compound, by separating 2-methylquinoline capable of readily forming an adduct with urea from quinoline, isoquinoline, 8-methylquinoline, etc. in the form of the adduct, purifying the adduct, and decomposing the purified adduct in an aqueous solution of a surfactant under heating.
CONSTITUTION: A 2-methylquinoline adduct with urea is decomposed in the presence of an aqueous solution of a nonionic surfactant, e.g. polyoxyethylene octyl phenol ether, having an HLB of 13W14, preferably in a concentration of 0.01W 0.40%, preferably in the presence of a solvent, e.g. an alkybvenzene or methyl isobutyl ketone, which will dissolve the aqueous solution of the surfactant and 2- methylquinoline but is substantially insoluble in water under heating to give the 2- methylquinoline.
USE: A raw material for a quinophthalone dye or pigment.
