Application of 38642-74-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.38642-74-9, Name is 2-Cyano-phenothiazine, molecular formula is C13H8N2S. In a Patent£¬once mentioned of 38642-74-9
A 2 – cyano phenothiazine preparation method (by machine translation)
The invention relates to a preparation method of 2-cyanophenothiazine. Dehydration reaction is firstly performed, thereby avoiding the complex technical step of performing dehydration refinement after the 2-cyanophenothiazine crude product is generated, and effectively reducing the product decomposition; meanwhile, the 2-cyanophenothiazine generation reaction is performed after dehydration to obviously reduce the recrystallization frequency in the refinement process, so that the recrystallization is only needed once, thereby greatly reducing the loss of the materials and energy sources, lowering the preparation cost and enhancing the reaction yield; and thus, the yield of the preparation method can reach 90.3% or above. Besides, the purity of the product is very high and can reach 99.5% or above, and the content of the impurity amide is less than 0.1%. In addition, the catalyst used by the method can effectively accelerate the reaction, shorten the reaction time and lower the reaction temperature, thereby enhancing the energy utilization ratio and further lowering the cost of the whole preparation process.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 38642-74-9, and how the biochemistry of the body works.Application of 38642-74-9
