Preparation method of acesulfame potassium composition

The invention relates to a preparation method of an acesulfame potassium composition. According to the preparation method, a proper amount of organic acid is added to adjust the pH value of a neutralization reaction solution so as to change the pH value of an acetoacesulfame triethylamine salt solution generated by acylation reaction, so that the subsequent cyclization hydrolysis yield is increased to 95% or above, and therefore, the content of organic impurities in the acesulfame potassium composition finished product is reduced, and the product quality is improved.

Triethylammonium-based protic ionic liquids with sulfonic acids: Phase behavior and electrochemistry

Six triethylammonium-based protic ionic liquids (PILs) and two molten salts were synthesized via a proton transfer reaction from sulfonic acid to triethylamine (TEA). The PILs were characterized by 1H NMR, 13C NMR, 1H/15N NMR and FT-IR spectroscopic methods. The phase behavior of the PILs was studied using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The temperature dependences of the PILs electrical conductivity, viscosity, and electrochemical stability window (ECW) were studied. The highest electrical conductivity and ECW values are registered in triethylammonium triflate. The thermal and electrochemical characteristics of the salts obtained in this work have been analyzed in comparison with the literature data by the properties of triethylammonium-based salts with sulfonic acids.

ACESULFAME POTASSIUM COMPOSITIONS AND PROCESSES FOR PRODUCING SAME

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.
