It further indicates that the predominant hydrocarbon structure is rosin and the complex acids of rosin oil. To verify this, the hexane soluble extract was washed with methanol, and the methanol soluble of the hexane soluble was evaluated by FTIR with the results again showing the rosin structure.
Further analysis of the methanol soluble portion of the hexane soluble fraction using DSC melt point determinations showed values of 11,21, and 24[degrees]C for the materials that were analytically determined to be rosin and complex acids of rosin oil (64% of the hydrocarbon containing portion of the deposit sample).
FTIR scans of the methanol insoluble of the hexane soluble indicated the presence of hydrocarbons, other than rosin, indicative of wax and base oil wavenumbers typical of hydraulic and thermal oils, in lower concentrations relative to rosin and complex rosin oil acids.
