  • Publication number: 20150011742
    Abstract: The present disclosure provides methods for producing chitosan derivatives and the derivatives formed by these methods. The processes of the present disclosure utilize electrochemical methods to functionalize and/or modify amine and/or hydroxyl groups present on chitosan, to form new derivatives. In embodiments, a chloro-chitosan derivative may be prepared. The altered cationic affinity of these derivatives make them excellent candidates for biomedical applications, including pharmaceuticals, as well as food applications.

  • Patent number: 8147672
    Abstract: A process for preparing sucrose-6-ester is provided, which comprises electrolyzing an electrolyte solution containing sucrose, an acylating reagent and a halide catalyst. Also disclosed is a process for preparing sucralose, which involves the preparation and chlorination of sucrose-6-ester followed by deacylation of the molecule. The process of the invention can be more readily performed with a higher yield than those in the art.

  • Patent number: 7955489
    Abstract: Methods for the production of erythrose and/or erythritol are provided herein. Preferably, the methods include the step of electrolytic decarboxylation of a ribonic acid or arabinonic acid reactant to produce erythrose. Optionally, the reactant can be obtained from a suitable hexose sugar, such as allose, altrose, glucose, fructose or mannose. The erythrose product can be hydrogenated to produce erythritol.

  • Patent number: 7141556
    Abstract: This invention relates to a process for the preparation of glucosamine sulfate, glucosamine hydroiodide, glucosamine pyruvate, glucosamine phosphate or their mixtures with glucosamine hydrochloride, by electrodialysis. Starting from glucosamine hydrochloride, the exchange of the Cl? for an anion selected from the group consisting of SO4 ?2, I?, CH3COCOO? and PO4?3 takes place during the process. The electrodialyser comprises a cathode, anode, and means of separation composed of anion exchange membranes, cation exchange membranes, bipolar membranes or by other suitable means of separation. This invention also relates to a glycosamine sulphate containing chlorides obtainable by the process, and its therapeutic use.

  • Patent number: 5744023
    Abstract: An electric current is passed through a mixed solution containing a saccharide(s) and an organogermanium compound, in a compartment whose anode side is defined by an anion exchange membrane and whose cathode side is defined by a cation exchange membrane, to separate and remove said organogermanium compound. In the present invention, an organogermanium compound can be very effectively separated and recovered from a mixed solution containing a saccharide(s) and said organogermanium compound. The present invention is particularly effective for separation and recovery of an organogermanium compound from a reaction mixture obtained when a compound having an aldose structure is isomerized into a compound having a ketose structure in the presence of said organogermanium compound.
