ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an oxidation catalyst and methods using the same for producing carbonyl compounds and hydroxy adduct compounds by oxidative cleavage of an olefinic double bond or addition reaction thereto.
A method for producing adipic acid by reacting, in the presence of sodium tungstate and trioctylmethylammonium sulfate, cyclohexene with an aqueous hydrogen peroxide is known (JP-A 2000-86574), and a method for producing an aldehyde by reacting an olefin with hydrogen peroxide, using heteropolyacid containing phosphorus or germanium, is also known (JP-B 6-84324).
However, yields of the desired products in these methods were not always satisfactory for an industrial scale of production.
SUMMARY OF THE INVENTION
According to the present invention, carbonyl compounds and hydroxy adduct compounds can be obtained by using a readily available oxidation catalyst, which can selectively provide desired compounds in an improved yield.
Thus, the present invention provides:
1. a method for producing at least one compound selected from a carbonyl compound and a hydroxy adduct compound by an oxidative cleavage or addition reaction of an olefinic double bond of an olefin compound,
which comprises
reacting an olefin compound with hydrogen peroxide, utilizing as a catalyst, at least one member selected from
(a) tungsten,
(b) molybdenum or
(c) a tungsten or molybdenum metal compound comprising
(ia) tungsten or (ib) molybdenum and
(ii) an element of Group IIIb, IVb, Vb or VIb excluding oxygen;
2. an oxidation catalyst composition obtained by reacting aqueous hydrogen peroxide with at least one member selected from
a tungsten or molybdenum metal compound comprising
(ia) tungsten or (ib) molybdenum, and
(ii) an element of Group IIIb, IVb, Vb or VIb excluding oxygen,
provided that said tungsten metal compound is not tungsten carbide;
3. an oxidation catalyst composition obtained by
reacting aqueous hydrogen peroxide with at least one member selected from
(a) tungsten,
(b) molybdenum, or
(c) a tungsten or molybdenum metal compound comprising
(ia) tungsten or (ib) molybdenum, and
(ii) an element of Group IIIb, IVb, Vb or VIb excluding oxygen,
and containing an organic solvent;
4. a method for producing a carbonyl compound of formula (II):

wherein a and b respectively represent 1 and 2, or 3 and 4, which comprises subjecting a hydroxy adduct compound of formula (III):

wherein X is a hydroperoxide group, and R

represents a group of formula:
wherein R′ is an alkyl, aryl or aralkyl group, and
7. a hydroxy adduct compound of formula (IIIa):
X—(R
