| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to novel compounds of formula T-B for use as dispersants and for inhibiting scaling and a method for production thereof, where B represents -X-N(W)(ZPO 3 M 2 ), X is a C 2 -C 50 hydrocarbon, optionally substituted with OH or COOH; Z is C 1 -C 6 alkylene; M is H; W is ZPO 3 M 2 ; T is selected from: (I)MOOC-X-N(U)-; (II) MOOC-C(X 2 ) 2 -N(U)-; (iii) MOOC-X-S-; (IVi) [X(HO) n (N-U) n ] n -; (Vi) U-N(U)-[X-N(U)] n -; (Vii) D-S-; (VIIIi) MOOC-X-O-; (IXi) MOOC-C(X 2 ) 2 -O; (Xi) NHR"- ; and (XIi) (DCO) 2 -N-. U is selected from C 1 -C 12 hydrocarbon chains, H and X-N(W)(ZPO 3 M 2 ); X 2 is selected from H, C 1 -C 20 hydrocarbon chains, optionally substituted C 1 -C 12 hydrocarbon groups, which can be substituted with COOH; n', n" and n"' are equal to 1; D and R" are selected from C 1 -C 50 hydrocarbon chains, optionally substituted with COOH; or the compound T-B is 3-phenoxypropylimino-bis-methylenephosphonic acid, wherein the compound T-B is not carboxypropyl-aminopropylimino-N-bis-(methylenephosphonic acid). n EFFECT: present method includes reacting a compound of formula Y-X-N(W)(ZPO 3 M 2 ), where Y is selected from Cl, Br, I, HSO 4 , NO 3 , CH 3 SO 3 , p-toluene sulphonate, with a reaction counterpart T, which corresponds to said fragments at pH≥7 and 55-100°C. n 11 cl, 20 ex |
