Abstract: A process for preparing polyamino monosuccinic acids, salts or chelates thereof by (a) reacting a maleic or fumaric acid ester or mixtures thereof with a polyamino compound in a primary alcohol as a solvent, (b) hydrolyzing the product obtained in step (a), and (c) separating the primary alcohol. The use of a primary alcohol as the solvent results in a markedly purer polyamino monosuccinic acid product and simpler reaction conditions than when the solvent is a secondary or tertiary alcohol.

Abstract: Alkaline earth and transition metal scaling such as calcium and magnesium scaling can be controlled or removed in pipes, vessels, heat exchanges, evaporators, and filters, and in the oil field applications such as, for example, for drilling, production, and recovery operations with the addition of an effective amount of 2-hydroxyethyl iminodiacetic acid (HEIDA) or a salt thereof.

Abstract: Solutions comprising at least one polyamino disuccinic acid and one or more polyamino monosuccinic acids are useful in gas conditioning (preferably as the iron chelate). The copper chelates are also useful in electroless copper plating. Another aspect of the invention includes the use of the aminosuccinic acid mixtures in laundry detergent compositions.

Abstract: 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.
