More Information
Summary:A process for the preparation of a solid composition of an amino acid diacetic acid compound wherein the amino acid diacetic acid compound is methyl glycine-N,N-diacetic acid or a salt thereof, or glutamic N,N-diacetic acid or a derivative thereof, as well as the product obtained by such process are disclosed. The process includes feeding a saturated or oversaturated aqueous composition of the amino acid diacetic acid compound in an aqueous solvent to a drum dryer, wherein the aqueous composition is fed to the drum surface with a layer thickness of from about 0.1 to about 10 mm, the drum has a surface temperature of from about 80 to about 180° C., and the drum operates at a tangential speed of from about 0.1 to about 100 m/min. The method further includes removing the mass from the drum before a full revolution of the drum.
