    • 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.
    • 本发明涉及制备式(I)的羰基化合物的方法,其中R 1为氢原子或具有1至3个C原子的烷基; R2是氢原子或式(II)的基团,其中R3是氢原子或与R4一起形成氧原子; R4是基团OR6或与R3一起形成氧原子; R5是氢原子,具有1至8个C原子的烷基或环己基或环戊基; 并且R 6是具有1至4个C原子的烷基,环己基或环戊基或式-CH 2 -CHO或-CH 2 -CH 2 -O-CH 2 -CHO的基团。 根据所述方法,羰基化合物是通过甲醇或式(III)醇的气相氧化生成的,其中R 1和R 5具有上面指定的含义,R 7是氢原子或OR 8基团,R 8 是氢原子,具有1至4个C原子的烷基,环己基或环戊基或式-CH 2 -CH 2 -OH或-CH 2 -CH 2 -O-CH 2 -CH 2 -OH的基团, 与含有氧气的气体在含有铜和/或银的催化剂存在下反应,以及在反应条件下挥发的磷化合物,使得磷的量(以P计算)相对于重量份数 的酒精使用量高达20 ppm。 所述方法的特征在于,磷的量以至少两部分加入:a)第一部分在催化剂床之前加入气态起始混合物,和b)在催化剂床中加入至少一个其他部分。

    • The invention relates to a method for producing carbonyl compounds of formula (I), wherein R1 is a hydrogen atom or an alkyl radical with 1 to 3 C-atoms and R2 is a hydrogen atom, a C¿2?-C4-alkenyl radical which can be unsubstituted or substituted one to three times with C1-C3-alkyl or a radical of formula (II), wherein R?3¿ is a hydrogen atom or an oxygen atom together with R4, R4 is the radical OR6 or an oxygen atom together with R3, R5 is a hydrogen atom, an alkyl radical with 1 to 8 C-atoms, a C¿2?-C4-alkenyl radical which can be unsubstituted or substituted one to three times with C1-C3-alkyl or a cyclohexyl or cyclopentyl radical and R?6¿ is an alkyl radical with 1 to 4 C-atoms, a cyclohexyl or cyclopentyl radical or a radical of formula -CH¿2?-CHO or -CH2-CH2-O-CH2-CHO by gas phase oxidation of methanol or alcohols of formula (III), wherein R?1 and R5¿ have the meaning given above and R7 is a hydrogen atom or a radical OR?8 and R8¿ is a hydrogen atom, an alkyl radical with 1 to 4 C-atoms, a cyclohexyl or cyclopentyl radical or a radical of formula -CH¿2?-CH2-OH or -CH2-CH2-O-CH2-OH with an oxygen-containing gas in the presence of catalysts containing copper and/or silver and optionally, a phosphor compound which is volatile in the reaction conditions, the quantity of phosphor (calculated as P) being up to 20 ppm in relation to the quantity in weight of alcohol used. The inventive method is characterised in that it uses a catalyst system consisting of one catalyst which is essentially phosphor-free and at least one catalyst containing phosphor-containing copper and/or silver.
