Abstract: A new series of dyes have been synthesized by condensation 2- (2’-amino 4’-methyl benzoyl) tetra chloro benzoic acid with various phenol such as mono, di and tri hydric phenol using concentrated sulphuric acid as the condensing agent. The resulting compounds are substituted tetra chloro phthalides having asymmetrical carbon atom attached to different phenyl rings such as 3- (2-amino, 4-methyl phenyl) -3- (phydroxy phenyl) tetra chloro phthalide, 3- (2-amino, 4-methyl phenyl) -3- (2, 4-dihydroxy phenyl) tetra chloro phthalide, 3- (2-amino, 4-methyl phenyl) -3- (2, 3-dihydroxy phenyl) tetra chloro phthalide, 3- (2-amino, 4-methyl phenyl) -3- (2, 5-dihydroxy phenyl) tetra chloro phthalide, 3- (2-amino, 4-methyl phenyl) -3- (2, 3, 4-trihydroxy phenyl) tetra chloro phthalide and3- (2-amino, 4-methylphenyl) -3- (2, 4, 6-trihydroxyphenyl) tetra chloro phthalide. The absorption spectra properties of as prepared tetra chloro phthalides were investigated in 95 % Ethanol.
