| titleOfInvention | PROCEDURE FOR PREPARATION OF CARBOXYL ACID SALTS FROM PRIMARY ALCOHOLS. |
| abstract | A method of manufacturing an aminocarboxylic acid salt comprising: a) contacting an aqueous solution of a primary amino alcohol with a hydroxide base selected from alkali metal hydroxides, alkaline earth metal hydroxides and ammonium hydroxides in the presence of an effective amount of a catalyst containing metallic copper at a temperature of 100 ° C to 220 ° C, forming a reaction mixture within a reactor, wherein said effective amount of catalyst is from 1% to 70% by weight of the amount of said primary amino alcohol, and b) reacting the mixture to convert the primary amino alcohol into an aminocarboxylic acid salt, in which the process further comprises maintaining the concentration of oxidized copper in the reaction mixture below 3,000 ppm, in which maintaining the concentration of oxidized copper in the reaction mixture it comprises exposing the catalyst to a reducing agent before contacting and The catalyst with the base hydroxide and primary amino alcohol in which the reducing agent comprises one or more of sodium borohydride, formaldehyde, hydrazine or salt thereof. |
