| titleOfInvention | The synthetic method of isobutyl group succinonitrile |
| abstract | The invention discloses a kind of synthetic method of isobutyl group succinonitrile, it is related to the preparing technical field of carboxylic acid nitrile compounds.Comprise the following steps：A, the hexene acid esters IV of 5 methyl, 2 cyano group 2 synthesis：Isopentyl aldehyde II, cyan-acetic ester III, catalyst are added in acetic acid, reaction temperature is at 0~30 DEG C, and stirring reaction obtains the hexene acid esters IV of 5 methyl, 2 cyano group 2；B, isobutyl group succinonitrile I synthesis：The hexene acid esters IV of 5 methyl, 2 cyano group 2 and catalyst are added in ROH alcoholic solvents, HCN is added, control temperature is at 20~80 DEG C, and stirring reaction obtains product isobutyl group succinonitrile I；Wherein, R is methyl or ethyl.Reaction condition of the present invention is gentle, and high income, by-product alcohol may apply in reaction dissolvent；Cost is low, meets environmental requirement, is adapted to industrialized production. |
