摘要： Disclosed is an improved process for the removal of acetone from a production system wherein acetic anhydride is produced by contacting a mixture comprising methyl iodide and methyl acetate and/or dimethyl ether with carbon monoxide in the presence of a carbonylation catalyst or catalyst system. The process comprises a water-methyl iodide extraction step wherein acetone is separated from a mixture of methyl acetate, methyl iodide and acetone.

摘要： Disclosed is a process for the preparation of aqueous solutions of acetoacetamide wherein diketene and aqueous ammonia having an ammonia concentration of 6.0 to 9.0 weight percent are continuously fed to a reaction zone at rates which maintain in the reaction zone a pH of 7.0 to 8.2 and a residence time of 20 to 150 minutes while (i) maintaining the temperature of the reaction zone at 40 to 75 °C and (ii) subjecting the contents of the reaction zone to vigorous agitation. An aqueous product solution having an acetoacetamide concentration of 25 to 35 weight percent is continuously removed from the reaction zone.
