| Abstract: | Using inorganic base as a catalyst, 2,2-dimethylolbutyraldehyde was prepared by the aldol condensation from formaldehyde and butyraldehyde. Then, taking hydrogen peroxide as an oxidant, 2,2-dimethylolbutyric acid was obtained. The reaction conditions including molar ratio, reaction time, solvent and reaction temperature were investigated. The structure of the product was confirmed by IR and NMR. |
