<p>Object of the present invention are novel solvent systems for the preparation of N-alkyl thiophosphoric triamide solutions, containing one or more glycol ethers of the general formula (I), wherein R<SUP>1</SUP> is hydrogen or methyl, R<SUP>2</SUP> is selected from the group consisting of C<SUB>1</SUB>-C<SUB>6</SUB> alkyl, C<SUB>3</SUB>-C<SUB>6</SUB> isoalkyl, C<SUB>4</SUB>-C<SUB>6</SUB> tertiary alkyl, n = 2-4, and optionally further auxiliary substances improving the stability and applicability properties of the solutions. Object of the invention are further compositions containing N-alkyl thiophosphoric triamide, containing at least one N-alkyl thiophosphoric triamide and the solvent system of the invention, and also the use of the composition containing N-alkyl thiophosphoric triamide.</p> |
