| Abstract：The traditional synthesis method of acetyl chloride with acetic acid and phosphorus trichloride was improved based upon the investigation on production processes of acetyl chloride in our country.Results showed that the yield of the product reached more than 96.3% with the increase of 6%bythe improved method than by the traditional method,and the purity was over 99.0%,demonstrating that the method had an advantage such as mild reaction condition,easy operation and control,little release of "the three wastes... |
