Abstract
A process for preparing ketones comprises reacting an alkene with carbon monoxide and a secondary alcohol at elevated temperature in the presence of a rhodium catalyst and an aminoalcohol or aminoether promoter. A preferred catalyst is Rh.sub.6 (CO).sub.16 and a preferred promoter is N(CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.3).sub.3.
Claims7
A process for the preparation of ketones, said process comprising reacting an alkene with carbon monoxide and a secondary alcohol at elevated temperature in the presence of a rhodium catalyst and a promoter selected from monoalkanolamines, dialkanolamines, trialkanolamines or etherified analogs thereof.
A process for preparation of ketones, which process comprises reacting a C.sub.1 to C.sub.6 mono-olefin with carbon monoxide and an alcohol selected from the group consisting of C.sub.3 to C.sub.10 secondary alcohols and C.sub.5 to C.sub.12 cyclic alcohols at a temperature in the range of 150.degree. to 230.degree. C. in the presence of a rhodium catalyst and a promoter selected from monoalkanolamines, dialkanolamines, trialkanolamines and etherified analogs thereof.
