Synthesis	101-77-9 62-53-3 569-61-9 Basic magenta was prepared by synthesizing 4,4'-((4-iminocyclohexane-2,5-diene-1-idene)methylene)diphenylamine hydrochloride by air oxidation reaction in the presence of a cesium vanadate catalyst using 4,4'-diaminodiphenylmethane and aniline as raw materials in the following steps: (1) in a four-necked flask, a mixture of 4,4'-diaminodiphenylmethane and aniline was added at a weight ratio of 20:1 to obtain Mixture A. Four ports of the four-necked flask were fitted with a condenser, a water separator, a thermometer and an air introduction tube, and the flask was equipped with a stirrer. aniline in a four-necked flask at a weight ratio of 20:1 to obtain mixture A. The four ports of the four-necked flask were respectively fitted with a condenser, a water separator, a thermometer, and an air introduction tube, and the flask was equipped with a stirrer; (2) under stirring conditions, a 30% HCl solution weighing 0.77 times the weight of 4,4'-diaminodiphenylmethane was added to mixture A until it was completely dissolved, obtaining solution B; (3) solution B was added to solution B weighing 1% to 4% by weight of 4,4'-diaminodiphenylmethane as cesium vanadate catalyst to solution B to obtain solution C; (4) heating solution C to 140° C. and continuously passing air at this temperature for 5 hours until no water is generated, and product D is obtained at the end of the reaction; and (5) azeotropic distillation of the product D, removing and recovering excess aniline to obtain crude oil. The crude oil was poured out of a four-neck flask and cooled to become brittle; (6) the brittle crude oil was ground and stirred with a dilute hydrochloric acid solution to pH ≤ 1 to obtain solution E; (7) solution E was stirred continuously for 6.5 hr, and then filtered through diatomaceous earth to obtain filtrate F; (8) the pH of the filtrate F was adjusted to 5 with a 0.4 mol/L NaOH solution at 24 °C, and filtered to obtain the filter cake G; ( (9) The filter cake G was dissolved in boiling water at pH=4, cooled to room temperature and left to crystallize for 16 hours, and finally filtered to obtain the solid product basic magenta crystals in 70% yield.
Potential Exposure	Used as a dye for textiles, paper;printing, computer and photo imaging inks, leather, andmany consumer products; as a microbiological/microscopystain for bacilli, including tubercle and influenza.
Carcinogenicity	Basic red 9 monohydrochloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.
Shipping	UN 3143 Dyes, solid, toxic, n.o.s., or dye intermediates,solid, toxic, n.o.s., Hazard Class: 6.1; Labels:6.1—Poisonous materials, Technical Name Required.
Properties and Applications	colourful red blue light. Slightly soluble in cold water, soluble in hot water for red, easily soluble in ethanol is cherry red. The strong sulfuric acid for yellow brown, after dilute for purple. Used in the manufacture of blue ink, also can dye tannins mordant dyeing cotton.
