Crystal violet lactone synthesis method (by machine translation)

Crystal violet lactone synthesis method, relates to a method for synthesizing the thermo-compression is sensitive dye, in order to urea, dimethyl aniline, inter-a aminobenzoic acid, P-dimethyl amino formaldehyde and other material as the raw material for synthesis, through the Schiff base stage, urea intermediate stage, colorless crystalviolet stage and the last stage of the oxidation reaction, synthetic crystal violet lactone. Synthetic method comprises the stage of: (1) Schiff base stage: to di-methyl amino formaldehyde and urea reaction generating Schiff base; (2) urea intermediate stage: a stage on the production of products and dimethyl aniline reaction to obtain the urea intermediate; (3) colorless crystal violet lactone stage: urea intermediate and inter-dimethylamino benzoic acid as a raw material reacts to produce a colourless crystalviolet; (4) oxidation reaction stage: colorless crystalline purple after hydrogen peroxide generating crystal violet lactone catalytic oxidation. The method to avoid impurity generated synthetic method, thereby improving the yield of the product, at the same time reduces the discharge of solid wastes. (by machine translation)

3-(substituted phenyl)phthalides

Process comprises the combination of the three steps of condensing 3-N(R)2 -4-X-benzoic acid with an aromatic or heterocyclic aldehyde, Y-CHO, under acidic conditions to produce 3-Y-5-X-6-N(R)2 phthalide (II), condensing said phthalide with a compound of the formula Z-H under alkaline or acid conditions to produce 2-(α-Y-α-Z)methyl-4-X-5-N(R)2 benzoic acid (III), and oxidizing said benzoic acid to produce 3-Y-3-Z-5-X-6-N(R)2 phthalide (I) where: R is hydrogen, non-tertiary alkyl of one to four carbon atoms, benzyl or substituted benzyl; X is hydrogen or halo; Y is 4-R1 -3-R2 -2-R1 -phenyl, 1-R5 -2-R6 -5/6-R4 -3-indolyl, 9-R7 -3-carbazolyl, 9-julolidinyl, 3,4-dioxymethylenephenyl, 2-thienyl, 1-R8 -2-pyrrolyl, or 4-pyridinyl; and Z is 4-R1 -3-R2 -2-R1 -phenyl, 1-R5 -2-R6 -5/6-R4 -3-indolyl or 1-R8 -2-pyrrolyl which are useful as colorless precursor color formers in carbonless duplicating and in thermal marking systems. The intermediates, 3-Y-5-X-6-N(R)2 phthalides (II) and 2-(α-Y-α-Z)methyl-4-X-5-N(R)2 benzoic acids (III) also have utility as colorless precursor color formers in carbonless duplicating and thermal marking systems.
