2-アミノアセトニトリル·塩酸塩

製造方法Synthesis of Aminoacetonitrile Hydrochloride by Reaction of Aminoacetonitrile with Hydrogen Chloride in Methanol: mixing the aminoacetonitrile with hydrogen chloride methanol solution, reacting at 45-50°C for 1-2 hours, cooling to below 5°C, filtering, and centrifugalizing to obtain the aminoacetonitrile hydrochloride, wherein in the hydrogen chloride methanol solution, the content of hydrogen chloride is 30-50 wt%, and the water content is less than or equal to 1%.Preparation method of aminoacetonitrile hydrochloride

純化方法The salt recrystallises from dilute EtOH as hygroscopic leaflets. It is best to crystallise it from absolute EtOH/Et2O (1:1) and then recrystallise it from absolute EtOH. The melting point recorded ranges from 144o to 174o. The free base has b 58o/15mm with partial decomposition.
