Abstract
Abstract An HPLC Group-Type Separation was developed for the analysis of the liquefaction product of sugar cane wood fibers (bagasse). First, a liquid-liquid extraction technique was applied to separate the highly polar and polymerized aqueous fraction from the less polar organic fraction. This last fraction was then separated by HPLC into four classification groups: three hydrocarbons (saturates, olefins and aromatics) and a combination of polar compounds. The application of these extraction and separation methods to the analysis of Brazilian sugar cane residue liquefaction products was very promising since the major group present in the extract is the aromatic hydrocarbons, suggesting its potential use as chemical feedstock, as well as a possible renewable source of energy. In addition, the method generates discrete and “clean” fractions for further detailed characterization when desired.
