Abstract
PURPOSE: To produce quinophthalone dye of good quality in high yields which does not contain carboxylic acid material, by reacting hydroxy-quinophthalone-carboxylic acid cpd. with an alcohol in the presence of sulfonic acid or sulfuric acid.
CONSTITUTION: A cpd. of formula I (wherein X is H, halogen atom; Y is H, halogen atom, alkyl, alkoxy; n is 1 or 2) is reacted with an alcohol of formula ROH (wherein R is alkyl, cycloalkyl, alkenyl) in the presence of a cpd. of formula D-SO3H (wherein D is aliph. or arom. residue) or sulfuric acid. Examples of the cpd. of formula I are 3'-hydroxy-quinophthalone-4-carboxylic acid, 5-chloro-3'- hydroxy-quinophthalone-4-carboxylic acid, etc. Examples of the cpd. of formula D-SO3H are p-toluenesulfonic acid, benzenesulfonic acid, etc.
