Abstract: The invention concerns the production of epoxides fromolefins using aromatic peroxycarboxylic acids. Followingepoxidisation (step A), the aromatic carboxylic acids therebyproduced are separated from the epoxides and catalyticallyhydrated (step B) to form the corresponding aromatic aldehydeswhich are then oxidised (step C) with oxygen or with anoxygen-containing gas mixture to form again the aromaticperoxycarboxylic acids which can be used again to produce theepoxides.9 claims

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. -
