| titleOfInvention | Acetyl chloride decoloring method and application of acidic strong oxidant in acetyl chloride decoloring |
| abstract | The invention discloses an acetyl chloride decoloring method, which comprises the following steps: s1: adding an acidic strong oxidant into the discolored acetyl chloride while stirring at the temperature of not higher than 45 ℃; the mass ratio of the acidic strong oxidant to the acetyl chloride is 1: 250-1: 1000; s2: heating until fractions appear, and carrying out total reflux reaction; s3: after the total reflux reaction is finished, rectifying the mixture at the temperature of not higher than 85 ℃ until the flow is cut off. The invention also discloses the application of the acidic strong oxidant in the decoloring of acetyl chloride. The method disclosed by the invention can remove organic matters which contain unsaturated bonds and have more active properties from acetyl chloride, effectively prevent the acetyl chloride from discoloring in transportation and storage, and improve the use value of the acetyl chloride. |
