Production of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate comprises: (A) reaction of isobutyraldehyde in the presence of an aqueous alkalimetal hydroxide as a basic catalyst, to give an organic phase comprising a mixture of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 2,2,4-trimethyl-1,3-pentanediol, and an aqueous phase comprising the alkalimetal hydroxide and alkalimetal isobutyrate; (B) separation of the aqueous phase; (C) optional removal of a portion of the resulting mixture from the process and/or separation of the mixture into its components followed by optional removal of the separated 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; (D) reaction of at least a portion of the mixture from step (B) with isobutyric acid under conditions of esterification to form 2,2,4-trimethyl-1,3-pentanediol diisobutyrate; and (E) optional recovery of the product.

Abstract: The invention relates to a method for the epoxidation of an organic compound comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent. Said method is characterised in that a product mixture containing .alpha.-hydroperoxy alcohols is reduced using at least one reductant. The invention also relates to a method for the epoxidation of an organic compoun d comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, characterised in that said method comprises at least the following steps: (i) an organic compound comprising at least one C-C double bond is reacted with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to obtain a product mixture P1 containing .alpha.-hydroperoxy alcohols; (ii) an epoxide that has been obtained by the reaction in step (i) is separated from P1 or P1', together with the non-converted organic compound comprising at least one C-C double bond, to obtain a product mixture P2 or P2', P2 containing the .alpha.- hydroperoxy alcohols that have occurred as by-products in the reaction in st ep (i) and P2' being substantially devoid of .alpha.-hydroperoxy alcohols. (iii ) at least one reductant is added to P1 and/or P2, whereby the .alpha.- hydroperoxy alcohols are converted into corresponding glycols, obtained in a product mixture P1' or P3.

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: Enol ethers of the formula Iwhere R1 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical which may carry further substituents which do not react with acetylenes or allenes, and the radicals R, independently of one another, are hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which may be bonded to one another to form a ring, and m is 0 or 1, are prepared by reacting an acetal or ketal of the formula IIwith an acetylene or allene of the formula III or IVwhere R and R1 have the abovementioned meanings, in the gas phase at elevated temperatures in the presence of a zinc- or cadmium- and silicon- and oxygen-containing heterogeneous catalyst.
