Title:
METHOD AND APPARATUS FOR PROCESSING HYDROLYSIS REACTION PRODUCT CONTAINING ACESULFAME
Document Type and Number:
WIPO Patent Application WO/2023/123405
Kind Code:
A1
Abstract:
The present application discloses a method for processing a hydrolysis reaction product containing acesulfame, comprising the following steps: step 1, letting the hydrolysis reaction product containing acesulfame stand and separate into layers, to obtain a separated water phase and organic phase; step 2, extracting the water phase using an organic extraction agent, and rinsing the organic phase with a rinsing agent. The method of the present application can improve hydrolysis conditions, and effectively reduce pollution caused by hydrolysis.
