Preparation of aliphatic carboxylic acids by oxidation of monocyclic ketones |
摘要 |
Aliphatic carboxylic acids, e.g., adipic acid, are prepared by oxidizing a monocyclic ketone with molecular oxygen or an oxygen-containing gas, in the presence of a catalytically effective amount of a vanadium compound having one of following formulae (I) and (II): H3+n[PM12-nVnO40]xy H2O (I) VO(Y)m (II) in which n is an integer greater than or equal to 1 and less than or equal to 6; M is a molybdenum or tungsten atom; y is an integer ranging from zero to less than 50; Y is an acetylacetonate group or an alkoxy radical containing from 1 to 10 atoms; and m is 2 or 3.
