N,N-Dicyclohexyl-2-benzothiazolesulfenamide Use and Manufacturing
(1) Disposing an M-Na salt solution: mixing 400 g of the promoter MBT with 360 g of a 32 wtpercent NaOH solution, and stirring at 50 ° C for 2 h to prepare an M-Na salt solution;A hydrochloric acid solution of cyclohexylamine was placed: 567 g of dicyclohexylamine was mixed with 376 g of industrial hydrochloric acid having a concentration of 31percent by weight.Adding 567 g of water and stirring at 35 ° C to obtain a hydrochloric acid solution of cyclohexylamine;(2) M-Na salt solution, dicyclohexylamine hydrochloric acid solution, Solvent toluene and sodium hypochlorite solution with 17percent effective chlorine content according to M-Na salt solution 69mL/min, Dihydrohexylamine hydrochloride solution 136mL / min, Toluene 130mL / min and sodium hypochlorite solution 49mL / min speed into the microchannel reactor for oxidation reaction, the reaction residence time is 2s, the reaction temperature is 30 ° C, the microchannel reactor is 4 reactors in series, The volume of each reactor was 3.2 mL, and the total volume of the reactor after the series was 12.8 mL;(4) Collecting the material flowing out of the reactor, and crystallization after stirring to a temperature of 5 ° C;The crude product is washed once with 200 mL of isopropyl alcohol aqueous solution and washed twice with 200 mL of water to obtain DCBS wet material. After drying, DCBS finished product can be obtained.The DCBS yield of this example was determined to be 96.2percent (based on the content of MBT), the purity of DCBS was 99.2percent by weight, and the appearance was a pale yellow powder. After the waste water was continuously distilled to recover isopropanol, the residual COD was 5900 ppm.General procedure: To a stirred solution of benzothiazole-2-thiol (1equiv) and cyclohexylamine (2.5equiv), the sodium hypochlorite solution was added slowly at 45°C. The completion of oxidation was confirmed by bluestone solution and KI starch solution. The reaction solution was cooled to room temperature and the precipitate was separated out. Then precipitate was washed by 9percent cyclohexylamine aqueous solution. Without further purification, the precipitate was filtered off to give the products.
