Embodiment 1
[0031] (1) Add 3g of [C 4 mim][CF 3 SO 3 ] solution, add 4g of NaH 2 PO 4 2H 2 O, then add 3 g of pre-prepared mixed solution of 5-hydroxymethylfurfural and 25 mg / mL fructose with a mass concentration of 1.0 mg / mL.
[0032] In order to test the accuracy of the data, each sample was equipped with three parallel experiments.
[0033] (2) After the ionic liquid two-phase aqueous system was prepared, it was shaken on a vortex shaker for 5 minutes to ensure that the whole system was evenly mixed, and then placed in a constant temperature water bath at 25°C for 1 hour. After the phase separation was completed, the upper and lower phase solutions were taken respectively for the determination of the concentrations of 5-hydroxymethylfurfural and fructose.
[0034] (3) in the present invention, the mensuration method of 5-hydroxymethylfurfural concentration is ultraviolet spectrophotometry, observes according to ultraviolet scanning figure, has two wave peaks, considers [C 4 mim]...
