Title:
PRODUCTION OF SATURATED ESTER
Document Type and Number:
Japanese Patent JP3852972
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To produce a saturated ester known as an industrially important compound frequently used as a solvent or a reaction solvent in high yield accompanying little decomposition reaction by hydrogenating an ester containing unsaturated group in the presence of a specific catalyst.
SOLUTION: An ester containing an unsaturated group and expressed by the formula (R1 to R5 are each a 1-10C alkyl; R6 is a 1-10C alkyl) is hydrogenated by using a hydrogenation catalyst containing 10-100wt.% of nickel. The hydrogenation catalyst is preferably a Raney-nickel or a supported nickel. The compound of the formula is preferably allyl acetate, crotyl acetate, methallyl acetate, allyl propionate, crotyl propionate, etc., and the reaction temperature is preferably 30-200°C. The reaction is preferably carried out under atmospheric pressure in the case of a gaseous phase reaction and under 15-50kg/cm2 pressure in the case of a liquid-phase reaction. The present process does not necessitate a complicate reaction apparatuses and reaction steps, the catalyst is easily available because it contains inexpensive nickel as a main compound and, accordingly, the objective saturated ester can be produced at a low cost.
