Systematic Analysis of Natural Raw Waxes (Carnauba Wax, Candelilla Wax and Bees Wax) and Pattern-Analysis of Carbon Chain Length of Their Components

Abstract

A systematic separation of natural raw waxes, carnauba wax, candelilla wax and bees wax, has been carried out and the results of the pattern-analysis of their components are described. Both non-aqueous media anion exchange resin column and silicagel column chromatography under 45° C were used for the isolation, and the method of systematic analysis was established. The isolated substances were characterized by IR, TLC etc. The distribution of carbon chain length was determined by use of the programmed temperature gas chromatography on SE-52 as liquid-phase. Their carbon chain length was determined by the method (advanced method of vapour-phase hydrogenation and gas chromatography) developed by us in the previous paper. It was found in this study that each raw wax showed its characteristic distribution of carbon chain length.
