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.
