Abstract:
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.

Claim (Index 21):
A process for producing a finished acesulfame potassium composition, the process comprising the steps of:\n (a) reacting sulfamic acid and triethylamine to form an amidosulfamic acid salt; (b) reacting the amidosulfamic acid salt and diketene to form acetoacetamide salt; (c) providing a cyclizing agent composition comprising a sulfur trioxide and dichloromethane and having an initial temperature; (d) cooling the cyclizing agent composition to form a cooled cyclizing agent composition having a cooled temperature less than 35\u00b0 C.; (e) reacting the acetoacetamide salt with sulfur trioxide in the cooled cyclizing agent composition to form a cyclic sulfur trioxide adduct; (f) hydrolyzing the cyclic sulfur trioxide adduct to form an acesulfame-H composition comprising acesulfame-H; (g) neutralizing the acesulfame-H in the acesulfame-H to form a crude acesulfame potassium composition comprising non-chlorinated acesulfame potassium and from 1 wppb to 39 wppm 5-chloro-acesulfame potassium acid, (h) treating the crude acesulfame potassium composition to form the finished acesulfame potassium composition comprising acesulfame potassium and less than 37 wppm acetoacetamide-N-sulfonic acid,\n wherein steps (a), (b), (c), and (d) can be performed in any order before the performance of step (e) and wherein the cooled temperature is at least 2\u00b0 C. less than the initial temperature, and wherein the providing step (c) comprises the step of contacting the solvent and the cyclizing agent to form the cyclizing agent composition; and wherein a contact time from the beginning of the contacting step to the beginning of reacting step (e) is less than 60 minutes.
