An improved process for chlorination of sugars produces chlorodeoxy derivatives, in particular the chlorination of sucrose-6-esters to produce sucralose (4,1′,6′-trichloro-4,1′,6′-trideoxy galactosucrose), with thionyl chloride and N,N-dimethyl formamide (DMF) at the ration of about 1 molar equivalent of thionyl chloride for every molar equivalent of free hydroxyl group.

A crystalline form of sucralose, and a method of making it. The method involves continuously crystallizing sucralose from an aqueous solution by a process providing continuous removal and recirculation of the vessel contents, and providing a long residence time for sucralose in the system. The crystals thus formed are of a relatively low length/diameter ratio, have an unsymmetrical shape, and exhibit good stability. The larger crystals in particular are tapered as compared to the rod-like larger crystals in prior art product.

The invention discloses a cross-linked polymer of at least one carbohydrate component comprising at least one primary alcohol function in particular for the manufacture of a composition which is intended to be applied onto the skin to obtain a tensing and/or toning effect.

Compositions which inhibit corrosion and alter the physical properties of concrete (admixtures) are prepared from salt mixtures of hydroxycarboxylic acids, carboxylic acids, and nitric acid. The salt mixtures are prepared by neutralizing acid product mixtures from the oxidation of polyols using nitric acid and oxygen as the oxidizing agents. Nitric acid is removed from the hydroxycarboxylic acids by evaporation and diffusion dialysis.
