Abstract

The invention discloses a production process of phthalocyanine blue series dye direct blue 199. The production process comprises the following steps: adding chlorosulfonic acid and copper phthalocyanine in a four-necked bottle, stirring and pulping for 1.5 to 2.5h in a sealing state, performing temperature rise for 135 to 140 DEG C, and performing heat preservation for 2.5 to 3.5h, cooling to roomtemperature, using ice to dilute dye, and filtering to obtain a sulfonated filter cake for later use; adding the sulfonated filter cake to a three-necked bottle, then adding industrial ammonia waterand ethylene glycol, stirring for 4h at room temperature, performing temperature rise slowly to 40 to 45 DEG C, reacting for 4h until the dye is completely dissolved; carrying out temperature rise to70 to 75 DEG C, stirring for 2.5h, removing ammonia until pH is 6.5 to 7.5, then cooling to room temperature, and adjusting pH to be 8 to 9 to prepare the phthalocyanine blue series dye direct Blue 199. The production process of the phthalocyanine blue series dye direct blue 199, disclosed by the invention, solves the problems of generation of pressure-filtration wastewater and the difficulty in membrane filtration in salting out of the traditional process, and the sulfonation degree is improved, so that the affinity of the dye and paper becomes better, and the coloring effect of the paper isincreased.

Description

technical field [0001] The invention belongs to the technical field of dye production technology, and in particular relates to a production technology of direct blue 199, a phthalocyanine blue series dye. Background technique [0002] Phthalocyanine blue, also known as copper phthalocyanine, is a phthalocyanine dye and one of the important advanced organic dyes. It has strong tinting power (several times that of Prussian blue and more than 20 times that of ultramarine blue), bright color, no fading, high temperature resistance, sunlight resistance, organic solvent resistance and chemical resistance, as well as fine particles. It is widely used in ink, paint, plastic, rubber, linoleum, lacquered paper, artificial leather, emulsified paint, painting watercolor, oil paint, paint printing, stationery and other coloring. At the same time, it is also used as a raw material for the manufacture of phthalocyanine reactive dyes, phthalocyanine direct dyes, and phthalocyanine polycond...
