Popis: | The novel separation of the constituent phenols in technical cashew nut-shell liquid from the industrial processing of Anacardium occidentale has been effected by high-performance liquid chromatography. The adsorption mode on columns of 5-μm and 10-μm Partisil and the reversed-phase partition mode with 5-μm and 10-μm Spherisorb bonded with octadecylsilane have been investigated. Determination of relative molar response values for the main constituent phenols and the use of an internal standard have led to a quantitative procedure by isocratic elution under reversed-phase partition, preferably with the solvent acetonitrile-water. Gradient elution with tetrahydrofuran and acetonitrile has also enabled the polymeric material to be estimated in the various types of technical cashew nut-shell liquid examined. |
