Paper Title:
Gas Column/Mass Spectrometry Analysis of Bio Oil Treated by Aqueous Two Phase System
  Abstract

Bio oil aqueous two phase systems were formed with ethanol and the salts of (NH4)2SO4, K2HPO4 and NaH2PO4 in bio oil on the ratio of 10:5:10(by mass). After phase separation, both the upper and the lower layers were analyzed by gas column/mass spectrometry (GC/MS). As a result, both K2HPO4/ethanol and NaH2PO4/ethanol system can enrich phenols and levoglucosan in the upperand lower layers,respectly, while NaH2PO4/ethanol system seldom changes the components of bio oil; the (NH4)2SO4/ethanol system is quit different with the other two and we have detected some components with nitrogen. Hence, NaH2PO4/ethanol is an advantage aqueous two phase system for bio oil treatment.
