摘要:
A process for producing acesulfame potassium, the process comprising the steps of providing a cyclizing agent composition comprising a cyclizing agent and a solvent and having an initial temperature, cooling the cyclizing agent composition to form a cooled cyclizing agent composition having a cooled temperature less than 35° C., reacting an acetoacetamide salt with the cyclizing agent in the cooled cyclizing agent composition to form a cyclic sulfur trioxide adduct composition comprising cyclic sulfur trioxide adduct; and, forming from the cyclic sulfur trioxide adduct in the cyclic sulfur trioxide adduct composition the finished acesulfame potassium composition comprising non-chlorinated acesulfame potassium and less than 39 wppm 5-chloro-acesulfame potassium. The cooled temperature is at least 2° C. less than the initial temperature.
