Abstract: The use of inorganic or organic polyacids to treat mineral fertilisers, in particular the use of polyacids as a mixture with at least one nitrification inhibitor to treat mineral fertilisers. The invention also concerns the use of selected pyrazole derivatives as inhibitors in mineral fertilisers and as stabilisers for liquid manure or liquid fertiliser formulations, and the treated mineral fertilizers themselves, as well as new pyrazole derivatives that can be used as nitrification inhibitors in mineral fertilizers and as stabilisers in liquid manure or liquid fertiliser 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.

Abstract: Separation of mixture of amine(s), water, low-boiling fraction and optionally high-boiling fraction includes optional distillative separation of low and high-boiling fractions, extraction of mixture with aqueous sodium hydroxide solution; and distillation of resultant aqueous-organic phase to recover anhydrous amine(s) from sump or side in separation part of column and amine/water azeotrope. Separation of a mixture containing amine(s) (I), water, low-boiling fraction (II) and optionally high-boiling fraction (III) comprises: (i) optional distillative separation of a first low-boiling fraction; (ii) optional distillative separation of a first high-boiling fraction; (iii) extraction of the mixture with aqueous sodium hydroxide (NaOH) solution, giving a first aqueous phase containing NaOH solution and a second aqueous-organic phase (IV) containing amines, other low-boiling fractions and optionally other high-boiling fractions; and (iv) distillation of the aqueous-organic phase to recover anhydrous amines as sump discharge or side discharge in the separation part of the column, an amine/water azeotrope, which is recycled to (iii), as side discharge in the concentration part and further low-boiling fraction as top discharge.

Abstract: A process for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent having a b.pt. of ?-50-200 deg C (normal pressure) is characterized by maintaining the concentration of 3-chloropropyne in the liquid phase and gas phase below the deflagration concentration by control of the type and amount of diluent, and by temperature and total pressure of the system.

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.
