Description
Technical Field
[0001] This application relates to the field of saccharin sodium production, and particularly to a device for feeding ammonia water in an amidation reaction. Background Art
[0002] Saccharin sodium is an artificial sweetener with the chemical name sodium o-sulfobenzimide. It is about 300 - 500 times sweeter than sucrose but contains no calories, so it is widely used in the food and beverage industries as a low-calorie or calorie-free sweetener substitute. The production of saccharin sodium usually involves multiple chemical steps, and the most core one is the amidation reaction of o-aminosulfobenzoic acid with acetic anhydride to produce o-sulfobenzimide, and then it is converted into the sodium salt.
