Preparation of omega-formylalkanecarboxylic esters |
摘要 |
omega -Formylalkanecarboxylic esters are prepared by hydroformylation of an alkenecarboxylic ester with carbon monoxide and hydrogen at elevated tempertures and under superatmospheric pressure in the presence of a cobalt carbonyl complex by a process in which an alpha , beta -unsaturated alkenecarboxylic ester is hydroformylated in the presence of from 0.01 to 1 mol %, calculated as cobalt, of a cobalt carbonyl complex, while maintaining a conversion of from 10 to 70% of alpha , beta -unsaturated alkenecarboxylic esters.
