| Abstract: | A powder of Zn with soluble cobalt salts were fed in a reactor,and sodium dithionite and methanol were added after CO was introduced to synthesize sodium tetracarbonylcobaltate which acted as the catalyst of the following methyl 3-hydroxypropionate synthesis in situ.Then methanol with ligands and CO were added and carbonylation of ethylene oxide was followed to produce methyl 3-hydroxypropionate(MHP) in the same reactor.The results reveal that acetate cobalt is a good catalysis precursor,the conversion and selectivity of methyl 3-hydroxpropanate were 80.52 % and 83.00 %,respectively. |
| Keywords: | cobalt-based catalyst hydroesterification methyl 3-hydroxypropionate |
