overview | 2-amino anthraquinone can be used as an intermediate in pharmaceutical synthesis. If 2-amino anthraquinone is inhaled, please move the patient to fresh air; if the skin is in contact, remove the contaminated clothes, rinse the skin thoroughly with soapy water and clear water, and see a doctor if you feel uncomfortable; if you are in contact with clear eyes, you should Separate the eyelids, rinse with flowing water or normal saline, and see a doctor immediately; if you eat, rinse your mouth immediately, prohibit vomiting, and see a doctor immediately. |
Use | 2-aminoanthraquinone is a derivative used to synthesize isonicotinic acid and used as anti-hyperlipidemia. 2-Aminoanthraquinone also has xanthine oxidase inhibitory activity and antimalarial activity. It is used to make anthraquinone dyes and other The intermediates of vat dyes are mainly used to make reduced blue RSN, reduced yellow G, reduced yellow 8G and 1-chloro-2-aminoanthraquinone dyes. In addition, it can be used as a catalyst in the paper industry to save caustic soda. |
production method | (1) it is prepared by ammoniating anthraquinone -2-sulfonate ammonium salt. the technological process is as follows: 240kg of anthraquinone -2-sulfonate ammonium salt, 70kg of m-nitrobenzene sulfonate (anti-dyeing salt S) and 174kg of 25% ammonia water (containing ammonia 100%) are pulped and pressed into an autoclave. Heating to 184-188 ℃, pressure 3.73-3.92MPa (gauge pressure), heat preservation pressure reaction for 10h, after reaction, cooling, ammonia release. Cold to 80 ℃, the material is pressed into the deamination pot at 80 ℃ for 2h. Raise the temperature to 100 ℃, suck and filter, and wash with 100 ℃ hot water 3000L. Drying the filter cake to obtain 2-amino anthraquinone. 70% yield. (2) 2-chloroanthraquinone and ammonia water were reacted at high temperature and pressure in the suspension of copper sulfate catalyst to prepare 2-aminoanthraquinone. First, 2-chloroanthraquinone, copper sulfate and ammonia are beaten, fully mixed and pressed into an ammoniated pressure cooker, heated to 213-215 ℃, reacted at a pressure of 5.1-5.39MPa for 5 hours, and discharged to recover residual ammonia. The reaction product is pressed into the filter, filtered, washed and dried to obtain the finished product. Product specification: the industrial product content (in terms of total ammonia value) with red brown powder appearance is 86.0%. Raw material consumption quota: 2-chloroanthraquinone (96%)1150 kg/t, ammonia water (95%)400 kg/t, copper sulfate (96%)87.8 kg/t. |
