Abstract: The use of inorganic or organic poly acids is claimed for treating mineral fertilisers containing a nitrification inhibitor. The use of compounds of formula (I) is claimed as nitrification inhibitors. R1 = H, halo or 1-4C alkyl; R2 = 1-4C alkyl; R3 = H or CH2OH, and when R3 = H, the compound may be converted to a phosphoric acid salt. A mineral fertiliser containing a poly acid and optionally (I) is also claimed. 3,4-dimethylpyrazole (Ia), 4-chloro-3-methyl-pyrazole (Ib), N-hydroxymethyl-3,4-dimethylpyrazole (Ic), N-hydroxymethyl-4-chloro-3-methylpyrazole (Id), acid addition salts of (Ic) and (Id), and mixtures of two or more of (Ia)-(d) are new.

Abstract: The invention relates to a method for producing a titanium silicate with RUT structure, which consists of the following steps: (i) preparation of a mixture of at least one SiO2 source and at least one titanium source; and (ii) crystallization of the mixture prepared in (i) in a pressurized vessel with addition of at least one template compound so that a suspension is obtained. The method is characterized in that amines or ammonium salts suitable for stabilizing cages of the silicate structure [4 5 6 ] and [4 5 6 8 ] are used as template compound.
