Abstract

2,2-Dimethylolheptanoic acid was prepared from 2,2-dimethylolheptaldehyde and hydrogen peroxide via oxidation.The structure of 2,2-dimethylolheptanoic acid was confirmed by IR and 1H NMR and 13C NMR.The results showed that the optimun conditions were as follows:molar ratio of hydrogen peroxide to 2,2-dimethylolheptaldehyde was 1.1∶1,reaction time was 8 h,the quality ratio of water to 2,2-dimethylolheptaldehyde was 3∶1,reaction temperature was 70 ℃,pH value was 4.The yield of 2,2-dimethylolheptanoic acid was 57.6%.
