GRANULES OF MGDA AND (METH)ACRYLIC ACID HOMO- OR CO-POLYMER; PROCESS FOR MAKING THE SAME

Process for making a granule containing(A) at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and of iminodisuccinic acid (IDS), and, optionally,(B) at least one homo- or copolymer of (meth)acrylic acid, partially or fully neutralized with alkali,sai...

Beschreibung
Zusammenfassung:	Process for making a granule containing(A) at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and of iminodisuccinic acid (IDS), and, optionally,(B) at least one homo- or copolymer of (meth)acrylic acid, partially or fully neutralized with alkali,said process comprising the steps of(a) providing an aqueous solution or slurry containing chelating agent (A) and, if applicable, (co)polymer (B),(b) removing most of said water by spray granulation in a fluidized bed,(c) treating the resultant granule in a vessel of which at least one part rotates around a horizontal axis and wherein said vessel is selected from paddle mixers, free-fall mixers and plough share mixers.
