摘要

Method for the production of powdered water-soluble tris (hydroxyethylidene diphosphonate) dyleza (III) Fe (HL) · mAm · nHO, tris (hydroxyethylidene diphosphonate) iron (III) Fe (HL) · kAm · nHO, manganese (II) oxyethylidene diphosphonate, MnHL qA bis (manganese (oxyethylidene diphosphonate) manganese (II) Mn (HL) grinding the resulting dry mass, characterized in that as a promoter astvorimosti an organic amine in an amount of k, m, p, q - equivalents selected from the group of monoethanolamine m = 5-7, k = 6-9, q = 2, p = 4-6; diethanolamine m = 5-6, k = 8-9, q = 2, p = 5-6; tris (hydroxymethylaminomethane) m = 6, k = 9, q = 2, p = 6; 2,2 ′ - (ethylidenedioxy) bis (ethylamine) m = 3, k = 5, q = 1, p = 3.
