| titleOfInvention | Method for producing carbonyl compound |
| abstract | (57) [Summary] The present invention provides a compound represented by the formula: [Wherein, R 1 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and R 2 is a hydrogen atom or a formula: (Wherein, R 3 is an oxygen atom together with a hydrogen atom or R 4, R 4 is an oxygen atom together with the group OR 6 or R 3, R 5 is a hydrogen atom or 1-8 And R 6 is an alkyl group having 1 to 4 carbon atoms, a cyclohexyl group or a cyclopentyl group, or a formula: —CH 2 —CHO or —CH 2 —CH 2 —O—CH 2 —CHO) is a group). According to the above method, the carbonyl compound is methanol or a compound of the formula: Wherein R 1 and R 5 are as defined above, R 7 is a hydrogen atom or a group OR 8 , and R 8 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a cyclohexyl group Or a cyclopentyl group, or an alcohol of the formula: —CH 2 —CH 2 —OH or —CH 2 —CH 2 —O—CH 2 —CH 2 —OH], using an oxygen-containing gas (copper and And / or silver) containing catalyst and phosphorus compounds which are volatile under the reaction conditions, wherein the weight of phosphorus (calculated as P) is less than 20 ppm, based on the weight of alcohol used. Then, it is manufactured by gas phase oxidation. The process comprises dividing the amount of phosphorus into at least two parts, a) one part being added together with a mixture of gaseous starting materials before it reaches the catalyst bed, b) at least one part A further part is characterized by being added into the catalyst bed. |
