Abstract
The presently disclosed subject matter is directed to nitrapyrin complexes and syntheses thereof finding particular utility in agricultural uses, e.g., directly applied to soil, or in combination with fertilizers to increase nutrient uptake and to inhibit nitrification and urease hydrolysis. More particularly, the subject matter is directed to nitrapyrin complexes, preferably containing specific types of carboxylic and sulfonate repeat units. Other uses of the nitrapyrin complexes and compositions containing nitrapyrin complexes are also disclosed.

A nitrapyrin complex comprising nitrapyrin complexed with a polyanion, wherein the nitrapyrin complex is formulated as an aqueous dispersion.
A composition comprising:
- a nitrapyrin complexed with a polyanionic polymer, wherein said polymer comprises:
- recurring polymeric subunits each made up of at least two different moieties individually and respectively taken from the group consisting of B and C moieties, wherein moiety B is a dicarboxylic moiety of the general formula
- and moiety C is a dicarboxylic moiety of the general formula
- wherein each R7 is individually and respectively selected from the group consisting of H, OH, C1-C30 straight, branched chain and cyclic alkyl or aryl groups, C1-C30 straight, branched chain and cyclic alkyl or aryl based ester groups, R′CO2 groups, OR′ groups and COOS groups, wherein R′ is selected from the group consisting of C1-C30 straight, branched chain and cyclic alkyl or aryl groups and X is selected from the group consisting of H, the alkali metals, NH4 and the C1-C4 alkyl ammonium groups, R3 and are individually and respectively selected from the group consisting of H, C1-C30 straight, branched chain and cyclic alkyl or aryl groups, R5, R6, R10 and R11 are individually and respectively selected from the group consisting of H, the alkali metals, NH4 and the C1-C4 alkyl ammonium groups, Y is selected from the group consisting of Fe, Mn, Mg, Zn, Cu, Ni, Co, Mo, V and Ca, and R8 and R9 are individually and respectively selected from the group consisting of nothing (i.e., the groups are non-existent), CH2, C2H4, and C3H6, each of said moieties having or being modified to have a total of two COO groups therein, all of the moieties making up the polymer being dicarboxylic moieties;
- and
- an organic solvent, wherein the organic solvent is selected from the group consisting of:
- aromatic 100 (CAS No:
- 64742-95-6), aromatic 200 (CAS No. 64742-94-5), sulfones, glycols, polyglycol, dipropylene glycol, Dow PT250, Dow PT700, triethylene glycol, tripropylene glycol, propylene carbonate, triacetin, Agnique AMD810, Agnique AMD3L, Rhodiasolv ADMA10, Rhodiasolv ADMA810, Rhodiasolv Polarclean, and mixtures thereof,
