Abstract
1363099 Alkali metal aminopolycarboxylates BADISCHE ANILIN- & SODA-FABRIK AG 17 Dec 1971 [18 Dec 1970 13 Oct 1971] 58652/71 Heading C2C Alkali metal salts of compounds of the formula in which R<SP>1</SP> is H or -CH 2 COOH or and A is -CH 2 COOH or a group where R<SP>2</SP> is H, -CH 2 COOH or -CH 2 CH 2 OH, and n is 0-5, are prepared by reacting an alkali metal cyanide, formaldehyde, and (where A is a group of Formula II) a compound of formula where R<SP>3</SP> and R<SP>4</SP> are H or -CH 2 CH 2 OH, in aqueous solution and separating the alkali metal salt by evaporating the resulting solution, at least part of the reaction solution, after its partial concentration and removal of precipitated product salt, being recycled to the reaction chamber. Examples prepare sodium nitrilotriacetate, ethylenediaminetetra-acetate and hydroxyethylethylenediaminetriacetate; other aminoacids are specified.
