Abstract
NEW MATERIAL:A quinophthalone compound of formula I (X is H or halogen; n is an integer 0W3).
EXAMPLE: The compound of formula II.
USE: A colorant for coloring and printing fibers yellows consisting of organic high polymer materials, e.g. polyethylene terephthalate or cellulose triacetate.
PROCESS: 2-Methyl-3-hydroxy-4-carboxy-quinoline or 2-methyl-3-hydroxy-quinoline is condensed with tert-butylphthalic anhydride, if necessary in the presence of a solvent, e.g. dimethylformamide, at 190W220°C. Chlorine in a molar amount of 1W8 times that of the raw materials is then absorbed at 70W90°C, if necessary, to halogenate the condensate at 100W150°C for 5W15hr with agitation.
