| Abstract: |
| With self-made methyl ricinoleate as raw material, the hydrolysis reaction properties of methyl ricinoleate were studied. The effects of reaction temperature, volume ratio of water to methyl ricinoleate, acidity and basicity and reaction time on the hydrolysis rate of methyl ricinoleate were investigated by single factor experiment. The results showed that the hydrolysis rate of methyl ricinoleate decreased in the order of alkaline, neutral and acidic hydrolysis. The lower the reaction temperature, the lower the hydrolysis rate of methyl ricinoleate. The smaller the volume ratio of water to methyl ricinoleate, the lower the hydrolysis rate of methyl ricinoleate. The hydrolysis rate of methyl ricinoleate decreased with the reaction time shortening. Under the conditions of acidic medium, volume ratio of water to methyl ricinoleate 1∶?1, reaction temperature 25?℃ and reaction time 60 min, the hydrolysis rate of methyl ricinoleate was 4.2%. It was advantageous for the washing of methyl ricinoleate under conditions of acidic medium, lower temperature and less water to reduce its hydrolysis loss. |
