1. Uses Used as dye intermediates, paper cooking agent and raw materials
2. Use as a pulp and paper pulp cooking aids, can reduce the amount of alkali, shorten the cooking time.
3. Use Most of anthraquinone is used in dyes, but the amount of vapalizing aid used as pulp is rapidly increasing.
(1) for the production of dyes anthraquinone as raw materials, the sulfonation, chlorination, nitrification, etc., can be a wide range of dye intermediates for the production of anthraquinone disperse dyes, acid dyes, vat dyes, the reaction Dyes, etc., to form a full-color dye grade. According to statistics, anthraquinone dyes have more than 400 varieties, in the field of synthetic dyes occupy a very important position.
(2) used as a papermaking pulp cooking agent in the alkaline cooking liquor only by adding a small amount of anthraquinone, you can speed up the delignification, shorten the cooking time, improve pulp yield and reduce waste load. There are more and more paper mills currently using anthraquinone additives. The consumption of anthraquinone as a cooking additive has grown rapidly. Anthraquinone and other applications. Anthraquinone compounds can be used for the production of high concentrations of ; in the fertilizer industry to produce desulfurization agent anthraquinone disulfonate. Used in the printing and dyeing industry as a dispensing aids.
4. Use of organic synthesis of high-level dye intermediates, such as indanthrene reductive dyes, acid dyes, some active dyes important raw materials. Used as paper cooking agent and raw materials, etc., can reduce the amount of alkali, shorten the cooking time. Used as a papermaking pulp cooking agent in the alkaline cooking liquor only add a small amount of anthraquinone, you can speed up the delignification speed, shorten the cooking time, improve the pulp yield, reduce waste load. There are more and more paper mills currently using anthraquinone additives.
