Abstract
Official abstract text for this publication.
The process of the invention is a process for the production of an aldehyde from the corresponding alcohol comprising the steps of feeding to a reactor a feed stream comprising said alcohol and an oxygen-containing gas; reacting said alcohol in the gas phase with said oxygen-containing gas in said reactor in the presence of a catalyst comprising oxides of iron and molybdenum, wherein the process further comprises the step of adding water to said feed stream. The process is particularly useful for the production of formaldehyde by the oxidation of methanol.
First claim
Opening claim text (preview).
1 . A process for the production of an aldehyde from the corresponding alcohol, comprising: feeding to a reactor a feed stream comprising said alcohol and an oxygen-containing gas; reacting said alcohol in the gas phase with said oxygen-containing gas in said reactor in the presence of a catalyst comprising oxides of iron and molybdenum; and adding water to said feed stream. 2 . The process according to claim 1 , wherein said reactor is operated at an inlet pressure of at least 1.5 bar G. 3 . The process according to claim 1 , wherein said oxygen-containing gas is air. 4 . A process according to claim 1 , wherein a portion of said feed stream comprises a recycled product stream from said process. 5 . The process according to claim 1 , wherein said feed stream comprises an alkyl ether. 6 . The process according to claim 5 , wherein said feed stream comprises at most 3% by volume of said alkyl ether. 7 . The process according to claim 1 , wherein water is added to said feed stream in an amount to produce a feed stream comprising water at a concentration of from 3% to 10% by volume of said feed stream. 8 . The process according to claim 1 , wherein said feed stream comprises alcohol at a concentration of from 1% to 20% by volume of said feed stream. 9 . The process according to claim 1 , wherein said catalyst comprises an alkali metal or an alkaline earth metal in addition to said oxides of iron and molybdenum. 10 . The process according to claim 9 , wherein said catalyst comprises from 50 to 300 ppm by weight of said alkali metal or alkaline earth metal. 11 . The process according to claim 9 , wherein said alkali metal is sodium. 12 . The process according to claim 1 , comprising reacting methanol with the oxygen-containing gas such that said alcohol comprises methanol and said aldehyde comprises formaldehyde.
