Abstract:
Compositions and processes for producing high purity acesulfame potassium are described. One process comprises the steps of providing a crude acesulfame potassium composition comprising acesulfame potassium and acetoacetamide, concentrating the crude acesulfame potassium composition to form a water stream and an intermediate acesulfame potassium composition comprising acesulfame potassium and less than 33 wppm acetoacetamide, and separating the intermediate acesulfame potassium composition to form the finished acesulfame potassium composition comprising acesulfame potassium and less than 33 wppm acetoacetamide. The concentrating step is conducted at a temperature below 90° C. and the separating step is conducted at a temperature at or below 35° C.

Claim (Index 25):
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; (f) neutralizing the acesulfame-H to form a crude acesulfame potassium composition comprising acesulfame potassium and acetoacetamide, (g) evaporating the crude acesulfame potassium composition to form a water stream and an intermediate acesulfame potassium composition comprising acesulfame potassium and less than 75 wt % water; (h) crystallizing the intermediate acesulfame potassium composition to form acesulfame potassium crystals; and (i) filtering the acesulfame potassium crystals to form the finished acesulfame potassium composition comprising acesulfame potassium and less than 10 wppm acetoacetamide, wherein the evaporating is conducted at a temperature below 50\u00b0 C. and wherein evaporator residence time is less than 30 minutes.
