| Abstract: | Methyl 3-hydroxypropanoate was synthesized from ethylene oxide by hydroesterification method in the paper.The composition and formation reason of products were studied by GC-MS analysis.Moreover,the influence of EO concentration,molar ratio of ligand / catalyst,time on the yield and selectivity have also been investigated.The yield and selectivity of methyl 3-hydroxypropanoate was 64.0 % and 95.7 % respectively at the optimum reaction condition: 5 mL/30 mL methanol,6∶1 ligand / catalyst ratio,4 h. |
| Keywords: | 1 3-propanediol ethylene oxide hydroesterification methyl 3-hydroxypropanoate |
