Abstract:
Compositions and processes for producing high purity acesulfame potassium are described. One process comprises the steps of forming a cyclic sulfur trioxide adduct; hydrolyzing the cyclic sulfur trioxide adduct to form an acesulfame-H composition comprising acesulfame-H; neutralizing the acesulfame-H in the acesulfame-H composition to form a crude acesulfame potassium composition comprising acesulfame potassium and less than 2800 wppm acetoacetamide-N-sulfonic acid, wherein the neutralizing step is conducted or maintained at a pH at or below 11.0; and 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.

Claim (Index 19):
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) contacting dichloromethane and a sulfur trioxide to form a cyclizing agent composition; (d) reacting the acetoacetamide salt with sulfur trioxide in the cyclizing agent composition to form a cyclic sulfur trioxide adduct; (e) hydrolyzing the cyclic sulfur trioxide adduct to form an acesulfame-H composition comprising acesulfame-H; (f) neutralizing the acesulfame-H in the acesulfame-H to form a crude acesulfame potassium composition comprising acesulfame potassium and less than 2800 wppm acetoacetamide-N-sulfonic acid, wherein neutralizing step is conducted at a pH at or below 11.0, (g) 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, wherein steps (a), (b), and (c) can be performed in any order before the performance of step (d).
