Patent

CA 2240321

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.

Nouvel intermédiaire utile à la synthèse de l'acide 2-hydroxyéthyl-iminodiacétique. L'intermédiaire peut être formé par la mise en contact de 2-hydroxyéthylamine avec du glycolonitrile, ce qui donne un aminonitrile qui peut être hydrolysé et mis en contact encore avec un glycolonitrile pour former l'intermédiaire nitrile, lequel pourra être converti en acide 2-hydroxyléthyl iminodiacétique par hydrolyse.
