Abstract

NEW MATERIAL:Quinophthalones of formulaI(R is amino, nitro, lower alkyl, lower alkoxy; X is Cl; Br; 1 is 0W3; m is 0W3; is 1W4 wherein 1+m is 0W3; p is 1W3).
USE: Quinophthalone pigment coloring synthetic resin yellow.
PREPARATION: The condensation reaction between a quinaldine of formula II and a halogen-substituted phthalic anhydride of formula III is conducted by dehydration in an inert organic solvent at 150W250°C for 2W10hr to form yellow pigment of formula IV. The product is dissolved in cocn. sulfuric acid and reacted with a halogenation reagent at 40W80°C for 2W8hr to introduce halogens into the quinophthalone.
