  • Patent number: 8497367
    Abstract: A process for the extraction of sucralose from an aqueous solution containing at least sucralose, other chlorinated saccharides, sodium chloride and dimethylammonium chloride into an organic solvent for sucralose by contacting said organic solvent with said solution to extract sucralose into the organic solvent. The ratio of sodium chloride to dimethylammonium chloride in the aqueous solution is increased prior to or during contact so as to increase the partition coefficient of sucralose into said organic solvent.

  • Patent number: 8476424
    Abstract: 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.

  • Patent number: 8436156
    Abstract: 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).
