1.In which a solution of sucrose and a trialkyl orthoester or a ketence acetal in an inert organic solvent is passed through a column of strong acid macroreticular resin to provide an eluate containing a sucrose alkyl 4,6-orthoester,water being continuously added to the eluate before passing the aqueous solution through a second column of acidic ion exchange resin to provide a mixture of sucrose 4-and 6-monoesters.
2.A solution of sucrose(300g) and trimethyl orthoacetate(135ml;1.2ME)in dimethylformamide was made up and cooled to 25℃.portions of this solution were passed down columns of three different ion exchange resin at ambient temperature at a rate of 10g/minute and the effluent was collected and analyzed by thin layer chromatography
