87691-88-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3-Piperazinobenzisothiazole hydrochloride, cas is 87691-88-1,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.
2. Preparation of ZPR in glycerol In a three necked flask was charged BITP HC1 (25g, 0. 098 mol), glycerol (62 ml), Na2C03 (13g) and the mixture was stirred for 10 minutes. CEI (5.9g) was added and the reaction mixture was heated for 3h at 115-120C. After 3h, the reaction was almost complete; after cooling to room temperature the solid was filtrated and was triturated in water and dried. The dried solid weights 42 g and the purity was 89.03%.
The chemical industry reduces the impact on the environment during synthesis,87691-88-1,3-Piperazinobenzisothiazole hydrochloride,I believe this compound will play a more active role in future production and life.
