Title:
METHOD FOR PRODUCING KETAL AND/OR ACETAL
Document Type and Number:
WIPO Patent Application WO2001081276
Kind Code:
A3
Abstract:
The object of the present invention is to produce ketal and/or acetal from olefins with a high conversion rate and a high selectivity. The present invention provides a method for producing a ketal and/or acetal by allowing olefins having at least one ethylenic double bond to react with oxygen and a polyhydric alcohol in the presence of a catalyst, which comprises carrying out the reaction in the presence of (a) palladium, (b) at least one metal other than palladium belonging to the groups 8, 9, 10 and 14 of the periodic table and (c) a halogen as the catalyst and a method for producing a ketone and/or aldehyde by hydrolyzing the ketal and/or acetal obtained by the above method in the presence of an acid catalyst.
