Abstract: Systems and method for production of furfural comprising combining a xylose-containing solution with an extraction solution comprising water-insoluble boronic acid to provide a first combined solution comprising an aqueous phase and a non-aqueous phase, said non-aqueous phase comprising xylose-diboronate ester (BA2X); combining at least a portion of the non-aqueous phase with an ionic conversion solution having a pH of less than or equal to 4 and comprising one or more salts to form a second combined solution, wherein the ionic conversion solution has a calculated molar ionic strength of at least 1, heating the second combined solution to convert at least a portion of the xylose-diboronate ester into furfural; separating the second combined solution into a second aqueous phase comprising from a second non-aqueous phase and recovering furfural from the second non-aqueous phase.
