Abstract
This invention relates to solvent compositions comprising an alkyl glycol ester-type solvent and a glycol-type solvent, non-aqueous solvent delivery formulations comprising the solvent composition, a urease inhibitor dissolved in the solvent composition, and fertilisers comprising a urea-based component and the non-aqueous solvent delivery formulation and the use of the fertilisers in agricultural applications.
Claims22
A solvent composition, the solvent composition comprising:
- (A) an alkyl glycol ester-type solvent of the formula (I)
- wherein
- R is hydrogen or a linear or branched C1 to C5 alkyl group,
- R2 is hydrogen or a methyl group,
- R3 is hydrogen or a methyl group,
- X is from 1 to 4,
- R6 is a linear or branched C1 to C6 alkyl group,
- wherein R2 and R3 may be different for each X, and wherein X is the alkoxylation degree and a number average;
- and
- (B) a glycol-type solvent of the formula (II)
- wherein
- R4 is hydrogen or a C1 to C3 alkyl group,
- R5 is hydrogen or a C1 to C3 alkyl group, and
- Z is an integer from 0 to 4;
- and wherein the glycol-type solvent of the formula (II) and the alkyl glycol ester-type solvent of the formula (I) are in a mass ratio in the range of from 3:1 to 9:1.
