HIGH SHEAR PROCESS FOR ASPIRIN PRODUCTION

摘要

Use of a high shear mechanical device in a process for production of acetyl salicylic acid, by contacting acetic anhydride with salicylic acid in a high shear device. The disclosed process makes possible a decrease in mass transfer limitations, thereby enhancing production of acetyl salicylic acid. A system for production of acetyl salicylic acid is also provided in which a reactor is configured to receive the output from a high shear device, which is configured to receive, via one or more inlets, acetic anhydride, and salicylic acid and generate a fine dispersion or emulsion of reactants.
