Patent ID: 11434214

Abstract:
In general, the invention relates to a process for the preparation of acesulfame or a derivative thereof. More specifically, the invention relates to a process, to a product obtainable by the process and the use of a specified velocity of flow for improving yield in the preparation of acesulfame or a derivative thereof. The invention relates to a process for the preparation of a product, the product being 6-methyl-3,4-dihydro1,2,3-oxathiazin-4-one 2,2-dioxide or a derivative thereof, the process comprising the following steps: a. Contacting SO3 and acetoacetamide-N-sulfonic acid or a derivative thereof in a reactor with a reactor pressure to obtain the product; b. The product exiting the reactor to a region outside the reactor through an aperture at a velocity of flow higher than 0.9 m/s, the region outside the reactor having an external pressure which is lower than the reactor pressure.
