Phosphine ligands and N-ligands have received widespread attenti on in ligand selection for hydroformylation and hydro-methyl esterification of epoxide derivatives conducted over the carbonyl cobalt catalysts[19-20].Under the reaction conditions covering a temperature of 65°C，a time of 7 h，a pressure of6 MPa，and a methanol/EO molar ratio of 3:2，the effects of ligand-free condition，the phosphine ligand（triphenylphosphine oxide），the quaternary ammonium salt ligand（tetrabutylammonium bromide），and the N-containing ligand（imidazole，3-hydroxypyridine）on hydroesterification of ethylene oxide were studied，with the results shown in Table 1.
