| titleOfInvention | Acetone purification method |
| abstract | The invention relates to the field of chemical industry, and discloses an acetone purification method, which comprises the following steps: a. adding acetone to be purified into a reaction container with a stirring device, and adding a purifying agent into the acetone to be purified, wherein the mass of the purifying agent is 1-30% of that of the acetone to be purified, and the purifying agent is isocyanate and/or a derivative thereof; b. stirring, and carrying out reflux reaction for 1-5 hours; c. adding liquid organic amine and/or its derivative into the reaction container, wherein the mass of the organic amine is 1-30% of the mass of the acetone to be purified, and stirring for reaction for 30 min; d. and distilling the reacted solution to obtain purified acetone. The method overcomes the defects of the prior art and achieves better application effect in production experiments. |
