Embodiment 1-3

[0030] Embodiment 1-3: An anthraquinone pretreatment process, which includes the following steps:

[0031] A. Take the synthesized anthraquinone or commercially available anthraquinone, heat it to 40-50°C, add benzene until it just dissolves, hot filter the clear liquid, and concentrate the clear liquid to obtain an oil;

[0032] B. Take the oily substance obtained in step A, directly place it at -20~-10℃ to quench and add directly to the system the water layer of -20~-10℃ water / methyl tert-butyl ether saturated solution (including 0.1wt%-0.5wt% of PAA), stirring, quenching a large amount of anthraquinone, filtering and washing the filter cake with water at 0-5°C, and drying to constant weight.

[0034]

Embodiment 4-6

[0035] Example 4-6: A water-soluble anthraquinone composition prepared by the following steps:

[0036] Take the pretreated anthraquinone dry product, add dispersant, anti-precipitation agent, defoamer, organic solvent, water and polymer, stir and disperse to obtain a suspension;

[0037] Use a peristaltic pump to pump the suspension to a spray dryer at a speed of 0.5-2 mL / min for spray drying, which is then obtained.

Abstract

The invention discloses a water-soluble anthraquinone composition. The water-soluble anthraquinone composition is prepared from, by mass, 1% of anthraquinone, 0.5%-1.5% of dispersing agent, 0.3%-0.5% of anti-precipitation agent and 0.1%-0.3% of defoaming agent. The water-soluble anthraquinone composition has the effect of improving the anthraquinone solubility.

Description

Technical field [0001] The invention relates to a water-soluble anthraquinone composition. Background technique [0002] Anthraquinone (Anthraquinone, C 14 H 8 O 2 ), is an important chemical intermediate, widely used in dyes, medicines and pesticides and other fields. With the development of the application field of anthraquinone, its demand is also increasing. At present, anthraquinone is relatively tight in the international and domestic markets. The huge market demand for anthraquinone has brought spring to the development of anthraquinone. [0003] The Chinese patent with publication number CN1683305A and publication date on October 19, 2005 discloses a method for the synthesis of anthraquinone from o-benzoylbenzoic acid by ring closure, which includes the following steps: [0004] A. Put the o-benzoyl benzoic acid into the closed-loop reaction kettle, increase the temperature according to the conventional process and keep it warm until the surface water of the o-benzoyl benzo...
