| titleOfInvention | Alpha-amino cyclo nitrile compound preparation method |
| abstract | The invention discloses an alpha-amino cyclo nitrile compound preparation method. Cycloalkanone, organic amine salt or inorganic amine salt, and alkali metal cyanide or acetone cyanohydrin undergo a reaction with stirring in water at the temperature of 20 DEG C to 30 DEG C in the absence of a catalyst to prepare the alpha-amino cyclo nitrile compound. According to the method, the cycloalkanone, the organic amine salt or the inorganic amine salt, and the alkali metal cyanide or the acetone cyanohydrin are used as reaction raw materials which are cheap and easy to obtain; the water is used as a reaction solvent which is environment-friendly and has low cost; no catalyst is used, which has low cost and has no subsequent catalyst recovery trouble; the alpha-amino cyclo nitrile compound is prepared by a one-pot method, and the preparation route is short and the operation is simple; a reaction liquid only needs to undergo simple steps such as organic solvent extroperation, washing, dewatering and drying, organic solvent recovery and the like to obtain the high qualified product, and complicated processing steps such as column chromatography purification is not necessary; the prepared product has high purity of more than 91% and high yield of more than 90%; and the method can be operated continuously, has great production capacity, short production cycle and short production cost, and can be applied to industrialized mass production. |
