Amino nitrile intermediate for the preparation of 2-hydroxyethyl iminodiacetic acid |
摘要 |
A novel intermediate useful in the synthesis of 2-hydroxyethyl iminodiacetic acid is disclosed. The intermediate can be formed by contacting 2-hydroxyethyl amine with glycolonitrile to form an aminonitrile which can be hydrolyzed and contacted with additional glycolonitrile to form the nitrile intermediate which can be converted to 2-hydroxylethyl iminodiacetic acid via hydrolysis.
