Removal of pyridine and pyridine analogs from reaction mass containing sucrose esters

Page/Page column 2-3, (2010/09/07)
A process of removal of pyridine or a pyridine analogue from a composition or a Process Stream in a process of production of 4,1′, 6′ trichlorogalactosucrose is described comprising reacting pyridine with an acid, the said acid being used preferably in gaseous form, achieving complete precipitation of the salt of pyridine in higher alcoholic solvents and non-polar solvents, filtering off the precipitate of the said salt of pyridine to achieve removal of pyridine from the reaction system and optionally regenerating and recovering pyridine by reacting the said salt with alkali.
Novel process for preparing sucrose-6-esters
-
Page/Page column 4, (2009/04/24)
A process for preparing a sucrose-6-ester, a key intermediate to sucralose. The process contains (a) reacting sucrose with a di(hydrocarbyl)tin oxide or a 1,3-diacyloxy-1,1,3,3-tetra(hydrocarbyl)distannoxane in the presence of a secondary alcohol and an organic polar aprotic solvent, to prepare a mixture comprising 1,3-di-(6-O-sucrose)-1,1,3,3-tetra(hydrocarbyl)distannoxane and the secondary alcohol; and (b) adding an acylating agent to the mixture, thereby acylating the 1,3-di-(6-O-sucrose)-1,1,3,3-tetra(hydrocarbyl)distannoxane to prepare a sucrose-6-ester.
