Abstract: Macroporous dihydroxyborylated polystyrene resin was prepared in this paper through coupling m-aminophenylboronic acid and macroporous aminopolystyrene by diazotization. Some factors which influence the absorbing ability for fructose of the resin were investigated. Some factors which affect the elution curve were also studied. Fructose was successfully separated from the mixture of glucose and fructose when using the resin as the separating medium. The purity of the obtained fructose syrup was 99%, with a concentration of 106 mg/mL. This resin may potentially be used in industry for separating glucose and fructose.

Key words: Macroporous dinitrohydroxyborylated polystyrene resin, Fructose glucose syrup, Separation of fructose and glucose (Ed.: Q,L)
