Abstract
A process for esterification of carbonyl compounds is provided. The process forms a mixture of a carbonyl compound and an inorganic phosphorous compound. An inorganic base can be added to the mixture. The mixture is filtered and an alcohol and a titanate catalyst are added to the filtrate. The mixture is esterified at an elevated temperature.
Claims21
1-15. (canceled)
A process for the production of esters of organic carbonyl compounds with alcohols by carrying out an esterification reaction in the presence of a catalyst containing an inorganic phosphorus(I) compound and a titanate, which comprises:
- (1) mixing the organic carbonyl compound and the inorganic phosphorus(I) compound to form a mixture;
- (2) filtering the mixture;
- (3) adding the alcohol and the titanate to the filtered mixture to form an alcohol-carbonyl mixture;
- and
- (4) esterifying the carbonyl compound in the alcohol-carbonyl compound mixture.
The process as claimed in claim 15, wherein, the carbonyl compound comprises a hydroxyfatty acid containing 8 to 22 carbon atoms.
