Abstract
Description
technical field
[0001] The invention relates to a method for recycling by-products in the preparation process of iodosuccinimide. Background technique
[0002] Iodosuccinyl is a common iodine reagent with stronger activity than iodine, potassium iodate, etc. It is widely used in the fields of pesticides, medicine and fine chemicals. The structure is as follows:
[0003]
[0004] The preparation method of iodosuccinimide is described in the literature Synthesis of N-iodosuccinimide and its application in H 2 SO 4 as efficient iodination reagent for deactivated aromatic compounds[J].Russian Journal of Organic Chemistry(2001),37(10),1503-1504 and CN201410188992.5 have reports, the above literature patents use iodine and bromosuccinimide as Starting material, the reaction yields iodosuccinimide. The reaction principle is as follows:
[0005]
[0006] Above technological process all can inevitably produce iodine bromide by-product, and this by-product cannot be utiliz...
