Abstract: The invention relates to a liquid composition containing phosphoric or thiophosphoric triamide derivatives and suitable solvents selected from the group comprising esters of hydroxyacids, heterocyclic alcohols and their derivatives, cyclic carbonic acid esters and dicarboxyacid esters, optionally the composition may also contain glycol ethers and auxiliary substances. The invention further includes the use of this liquid composition as urease inhibitor in urea-containing fertilizers, in fertilizers and wastes of animal origin or in sprays masking animal urine odors.

Abstract: The invention provides a process for preparing N-(hydrocarbyl)phosphoric or thiophosphoric triamides with substantially improved yields and purity. Two equivalents of hydrocarbylamine are used in the reaction with phosphoryl or thiophosphoryl chloride and then with ammonia in an aromatic solvent. The invention further relates to N-(hydrocarbyl)phosphopric or thiophosphoric triamides having the purity of at least 98% wherein R is a hydrocarbyl group and X is O or S. (RNH)(NH2)2P=X ??(I).

Abstract: The invention relates to a composition containing flavanolignans, e.g., isolated from Silybum marianum, and basic amino acids and, optionally, other auxiliary substances, in the form of mixture, and to the method of preparation of these compositions by mixing the components and their homogenization. The invention is applicable particularly in the pharmaceutical industry, cosmetics, food industry, breweries, distilleries, and in the industry of beverage production.
