Description

Technical Field

[0001] The utility model relates to the technical field of pigment yellow 14 production, in particular to a pigment yellow 14 dispersion reaction device. Background Art

[0002] In the coating and ink industry, azo pigments are in the largest demand. Benzidine yellow pigments are important yellow organic pigments, and the main varieties include CI Pigment Yellow 12, Pigment Yellow 13, Pigment Yellow 14, Pigment Yellow 17 and Pigment Yellow 83. Among them, Pigment Yellow 14 is a green-yellow powder with bright color, strong tinting power, good transparency, and good application performance. It is one of the important varieties of benzidine organic pigments.

[0003] The existing literature reports a method for synthesizing Pigment Yellow 14: add 30% hydrochloric acid to a diazo kettle, add dichlorobenzidine, beat and dissolve, add water to dilute, add ice to cool, add sodium nitrite for diazotization, add diatomaceous earth or activated carbon for decolorization after diazotization, and filter to obtain diazo liquid. Add water and liquid alkali to a coupling kettle, stir and dissolve, then add hydrochloric acid or acetic acid, acid precipitation, add sodium acetate, then cool, add diazo liquid, coupling is completed, add liquid alkali to adjust the pH value, then heat, add rosin and calcium chloride, filter and wash after the reaction to obtain Pigment Yellow 14. Pigment Yellow 14 is produced in a dispersion reaction device. In order to increase the reaction rate, a stirring structure will be set inside. However, after the existing dispersion reaction device produces Pigment Yellow 14, due to the existence of a stirring structure inside, it is inconvenient to filter it directly inside the device.
