摘要： The present invention provides a method for producing sucralose from a feed stream resulting from the chlorination of a sucrose-6-acylate in a reaction vehicle. The feed stream includes a sucralose-6-acylate, the reaction vehicle, water, and salts. The salts include one or more selected from the group consisting of alkali metal chlorides, alkaline earth metal chlorides and ammonium chloride. The method includes: (i) deacylation of the sucralose-6-acylate by treatment with a base to afford a product stream comprising sucralose; (ii) partial removal of water and, optionally, reaction vehicle from the product stream of (i) in order to cause precipitation of the salts from the product stream; (iii) removal of the precipitated salts from the product stream of (ii); and (iv) isolation of sucralose from the product stream of (iii).

摘要： A method of making sucralose includes maintaining a solution of a sucralose-6-acylate in an aqueous solvent at a temperature in a range from −20° C. to 20° C. and at a pH of at least 12.2 and less than 14.0 for a period of time sufficient to deacylate substantially all of the sucralose-6-acylate. The method may employ purified sucralose-6-acylate as the starting material, or the sucralose-6-acylate may be present in a quenched reaction mixture resulting from chlorination of a sucrose-6-acylate. The quenched reaction mixture may be exposed to deacylation conditions either before or after removal of a tertiary amide that may be present in it. Sucralose is subsequently recovered to complete the process.

摘要： A method of removing a carboxylic acid from a liquid that contains a tertiary amide solvent includes a step of contacting the liquid with an extraction medium comprising an amine. The amine is immiscible with both water and the tertiary amide solvent, and the contacting step forms a de-acidified phase containing the tertiary amide solvent and a phase containing the extraction medium and the carboxylic acid. Both the liquid that contains the tertiary amide solvent and the de-acidified phase may also contain a sucrose-6-acylate.
