摘要: PURPOSE:To obtain the subject compound which is used as a synthetic intermediate of amino acids, agrochemicals and medicines and can be stored in the form of stabilized white crystals for a long period of time. CONSTITUTION:An aqueous aminoacetonitrile solution is combined with a mineral acid to effect neutralization lower than 35 deg.C. Then, a reductive substance such as sodium sulfite, subsequently an alcohol such as methanol is added to the mixture to precipitate crystals. The crystals are filtered, dried to give the subject compound. The aqueous aminoacetonitrile is obtained by reaction of glycolonitrile with aqueous or liquid ammonia. The process is in no need of heating to prevent the product from being deteriorated by discoloration and undesired polymerization, further the addition of a reductive substance inhibits the deterioration of the product during handling or storage.
