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 use of inorganic or organic polyacids to treat mineral fertilizers, in particular the use of polyacids as a mixture with at least one nitrification inhibitor to treat mineral fertilizers. The invention also concerns the use of selected pyrazol e derivatives as inhibitors in mineral fertilizers and as stabilizers for liqu id manure or liquid fertilizer formulations, and the treated mineral fertilizers themselves, as well as new pyrazole derivatives that can be used as nitrification inhibitor s in mineral fertilizers and as stabilizers in liquid manure or liquid fertilizer formulations.

Abstract: A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from -50° C. (223 K) to 200° C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.
