Abstract: A mixture (M1) comprising an alkene and oxygen is worked up by a process in which (i) oxygen is removed from the mixture (M1) by a nondistillative method to give a mixture (M2) and (ii) the alkene is separated off from the mixture (M2) by distillation.

Abstract: The invention relates to a method for producing an epoxide in the presence o f a zeolite catalyst, whereby (i) an alkene is reacted with a hydroperoxide in the presence of the catalyst in order to obtain the epoxide, and at least on e alkali metal salt is supplied to the reaction in at least one educt flow. Th e inventive method is characterised in that (ii) the supply of the at least on e alkali metal salt is cut off during the reaction, and the supply of hydroperoxide and alkene is continued.

Abstract: The invention relates to a method for producing propylene oxide, comprising at least the following steps: (a) propene is reacted with a hydroperoxide in a solvent in the presence of a zeolite catalyst, in order to obtain a mixture (G0), said mixture (G0) containing propylene oxide, solvent, non-reacted propene, non-reacted hydroperoxide and oxygen; (b) the propylene oxide is separated from the mixture (G0) in such a way that a mixture (G1) is obtained which comprises non-reacted propene and oxygen; (c) the mixture (G1) is brought into contact with a liquid medium containing at least solvent, in order to obtain the mixtures (G2) and (G3), said mixture (G3) containing a part of the non-reacted propene and oxygen, and said mixture (G2) containing the solvent and the rest of the propene, the separated mixture (G3) of non-reacted propene and oxygen having a ratio of oxygen to propene which renders the mixture (G3) non-inflammable, and the mixture (G2) supplying at least one reaction between the propene and the hydroperoxide.

Abstract: The invention relates to a method for producing a titanium silicate with RUT structure, which consists of the following steps: (i) preparation of a mixture of at least one SiO2 source and at least one titanium source; and (ii) crystallization of the mixture prepared in (i) in a pressurized vessel with addition of at least one template compound so that a suspension is obtained. The method is characterized in that amines or ammonium salts suitable for stabilizing cages of the silicate structure [4 5 6 ] and [4 5 6 8 ] are used as template compound.

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.
