【課題を解決するための手段】 本発明者らは、上記課題を解決すべく鋭意検討した結果、アミノニトリルを、塩基及び、アミノニトリル1モルに対して0.01モル以上、1モル未満のケトンの存在下、含水アルコール溶媒中で加水分解する方法であれば、均一系で反応することができ、ケトン由来の環化副生物等がほとんど生成することがないため、簡便に高品質のアミノ酸アミドを高収率で得ることができることを見出し、本発明を完成した。

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that aminonitrile is used in an amount of 0.01 mol or more and less than 1 mol based on 1 mol of base and aminonitrile. If it is a method of hydrolyzing in a hydroalcoholic solvent in the presence of a ketone, the reaction can be performed in a homogeneous system, and cyclized by-products derived from the ketone are hardly generated, so that high-quality amino acids can be easily prepared. The present inventors have found that amides can be obtained in high yield, and have completed the present invention.
本発明の製造方法に用いるケトンとしては、脂肪族ケトンが好ましく、アセトン、メチルエチルケトン、メチルイソブチルケトンが特に好ましい。本発明においては、これらを1種以上用いることができる。ケトンの使用量は使用するケトンの種類によって異なるが、アミノニトリル1モルに対して、0.01モル以上、1モル未満であることが好ましい。0.01〜1モル以下であれば、アミノニトリルの加水分解が十分促進されるとともに、生成するアミノ酸アミドとケトンとが反応して環化物が生成することがほとんどない。さらに、経済的観点から、アミノニトリル1モルに対して、ケトンが0.01〜0.5モルであることが特に好ましい。 As the ketone used in the production method of the present invention, an aliphatic ketone is preferable, and acetone, methyl ethyl ketone, and methyl isobutyl ketone are particularly preferable. In the present invention, one or more of these can be used. The amount of the ketone varies depending on the type of the ketone used , but is preferably 0.01 mol or more and less than 1 mol with respect to 1 mol of aminonitrile. When the amount is 0.01 to 1 mol or less, hydrolysis of aminonitrile is sufficiently promoted, and the generated amino acid amide and ketone hardly react to form a cyclized product. Further, from an economic viewpoint, it is particularly preferable that the ketone is 0.01 to 0.5 mol per 1 mol of aminonitrile.
