摘要：

Oils derived by thermochemical conversion of different lignocellulosic feedstocks have been comparatively characterized. The average molecular weights (MW) were determined of oils and their SESC-fractions by use of high performance gel permeation chromatography. The MW of the oils varied between 230 (spruce holocellulose) and 540 Dalton (spruce organosolv lignin), while those of the SESC fractions increased with increasing polarity. Capillary g. c. was used to quantify monomeric phenols. No aromatic compounds could be detected in the oil from pure cellulose. I. r. spectra of the oils were evaluated quantitatively; multiple linear regression analysis revealed that the amounts of different types of phenols and the oxygen content can be calculated approximately from the i. r. data.
