Abstract: PROBLEM TO BE SOLVED: To provide a method for fractionating an amine-containing mixture. SOLUTION: According to circumstances, (i) a (first) low boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, according to circumstances, (ii) a (first) high boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, (iii) the amine-containing mixture is subjected to extraction using a sodium hydroxide solution to produce a sodium hydroxide-containing aqueous first phase and an amine-, (further) low boiling point matter- and, according to circumstances, (further) high boiling matter-containing water-organic second phase, (iv) the water-organic second phase is distilled to produce a substantially anhydrous amine as a column bottom phase taken-out substance or as a lateral flow extract in the stripping part of a distillation column, an amine/water azeotropic mixture as a lateral flow extract in the concentration part of the column and a (further) low boiling matter fraction as a column top extract and the amine/water azeotropic mixture is returned to the extraction process (iii) and, according to circumstances, (v) the substantially anhydrous amine is refined or fractionated.

Abstract: PROBLEM TO BE SOLVED: To provide a method for fractionating an amine-containing mixture. SOLUTION: This method for fractionating the amine-containing mixture containing one or more kinds of amines, water, a low boiling-point material, and a high boiling-point material comprises (i) separating and removing the low boiling-point material from the amine-containing mixture by distillation, (ii) separating and removing the high boiling-point material from the amine- containing mixture by the distillation, (iii) extracting the resultant amine- containing mixture by using a sodium hydroxide solution to provide a first aqueous phase containing the sodium hydroxide and a second aqueous-organic phase containing the amine, (iv) distilling the second aqueous-organic phase to produce an amine/water azeotropic mixture and a substantially anhydrous amine, and returning the amine/water azeotropic mixture to the extracting step (iii).

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. -
