| titleOfInvention | The synthetic method of acetylsalicylic acid |
| abstract | This application involves a kind of synthetic methods of acetylsalicylic acid, the following steps are included: providing rare earth modified solid super acid catalyst, the solid super acid catalyst includes complex carrier, the sulfate radical being incorporated on complex carrier and the rare earth ion with complex carrier doping, and wherein complex carrier is combined by silica and aluminum oxide；Salicylic acid and acetic anhydride are reacted under the action of rare earth modified solid super acid catalyst, obtain acetylsalicylic acid.The synthetic method of above-mentioned acetylsalicylic acid; with rare earth modified solid super strong acid as catalyst; acetylsalicylic acid is prepared using salicylic acid, acetic anhydride as acetylization reaction raw material; during acetylization reaction, product yield high, catalyst corrodes equipment small; environmental pollution is small; the reusable rate of catalyst is high, simplifies product last handling process, low energy consumption. |
