摘要： The invention relates to a method for a Re2O7 doped catalyst support deactivated (deactivated catalyst) by a hydrocarbon mixture containing C2-C6 olefin (C2-6 lot) used during a metathesis. The inventive method consists in treating the deactivated catalyst at a temperature ranging from 400 to 800 °C with an inert gas (regeneration gas K1). Afterwards, the thus pre-treated deactivated catalyst is treated with said regeneration gas K1 and an oxygen-containing gas (regeneration gas K2).

摘要： The invention relates to a method for the production of 2-keto-L-gulonic acid-C1-C10-alkyl esters by esterification of 2-keto-L-gulonic acid hydrate with an anhydrous C1-C10-alkyl alcohol in the presence of an acid homogeneous catalyst in a reaction cascade consisting of at least two reactors, wherein one of said reactors is a tube reactor, without removing the water produced during esterification from the reaction chamber.

摘要： The invention relates to a method for producing carbonyl compounds of formula (I), in which R1 is a hydrogen atom or an alkyl radical with between 1 and 3 C atoms; R2 is a hydrogen atom or a radical of formula (II) in which R3 is a hydrogen atom or, together with R4, an oxygen atom; R4 is the radical OR6 or, together with R3, an oxygen atom; R5 is a hydrogen atom, an alkyl radical with between 1 and 8 C atoms or a cyclohexyl or cyclopentyl radical; and R6 is an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH¿2?-CHO or -CH2-CH2-O-CH2-CHO. According to said method, the carbonyl compounds are produced by gas-phase oxidation of methanol or alcohols of formula (III), in which R?1 and R5¿ have the meaning assigned above and R7 is a hydrogen atom or an OR8 radical, and R8 is a hydrogen atom, an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH¿2?-CH2-OH or -CH2-CH2-O-CH2-CH2-OH, with a gas containing oxygen, in the presence of catalysts containing copper and/or silver and a phosphorus compounds which is volatile under reaction conditions, in such a quantity that the quantity of phosphorus (calculated as P) in relation to the part by weight of alcohol used is up to 20 ppm. The method is characterized in that the quantity of phosphorus is added in the catalyst bed.

摘要： The invention relates to a method for producing carbonyl compounds of formula (I), in which R1 is a hydrogen atom or alkyl radical with between 1 and 3 C atoms; R2 is a hydrogen atom or a radical of formula (II), in which R3 is a hydrogen atom or, together with R4, an oxygen atom; R4 is the radical OR6 or, together with R3, an oxygen atom; R5 is a hydrogen atom, an alkyl radical with between 1 and 8 C atoms or a cyclohexyl or cyclopentyl radical; and R6 is an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH¿2?-CHO or -CH2-CH2-O-CH2-CHO. According to said method, the carbonyl compounds are produced by gas phase oxidation of methanol or alcohols of formula (III), in which R?1 and R5¿ have the meaning assigned above and R7 is a hydrogen atom or an OR8 radical, and R8 is a hydrogen atom, an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH¿2?-CH2-OH or -CH2-CH2-O-CH2-CH2-OH, with a gas containing oxygen, in the presence of catalysts containing copper and/or silver, and a phosphorus compound which is volatile under reaction conditions in such a quantity that the amount of phosphorus (calculated as P), in relation to the part by weight of alcohol used, is up to 20 ppm. Said method is characterized in that the quantity of phosphorus is added in at least two parts: a) the first part is added with the gaseous starting mixture before the catalyst bed, and b) at least one other part is added in the catalyst bed.
