Abstract

The invention relates to the of saccharose, substituens especially to the obtaining of 4,1', 6'-trichlor-4,1',6'-trideoxygalactosaccharose (TGS) for the sweetening in necessary cases. For the increasing of selection and to simplify the process, the preliminary protection of oxygroups in 6-m saccharose position is done by means of acylating or (CH3CO)2O in pyridil at the room temperature or law temperature [(-30-(-50)°C], or with benzoylhalogenid in dichloromethane in/the presence of Na2CO3, at the environnement temperature with the obtaining of 6-mono-acetate (or benzoate) saccharose. Acylsaccharose obtained chlorates selectively in position 4,1',6', with a chlorous agent (chlorous sulphuryl), with subsequent deacylation and the separation of special product TGS with the efficiency until 15% at the content of 99%.Is rationally that before the chlorating 6-monoacetate of saccharose to separate on cation-exchange resin.The deacylation is by the treatment with natrium methyl in water solution, the extraction with dichloromethane (for the removing of tetrachlorderivers) and than with ethilacetate.
