GAS CHROMATOGRAPHIC ANALYSIS OF THE CHEMICAL COMPOSITION OF ETHYL ALCOHOL OBTAINED FROM PLANTS OF THE GENUS ASTERACEAE

Аннотация

In recent years, serious attention has been paid around the world to the chemical and biotechnological
processing of biomass of easily renewable plant raw materials. One of the most mass-produced aliphatic alcohols is
ethyl alcohol.
The aim of this work was gas chromatographic analysis of the chemical composition of ethyl alcohol obtained
from plants of the genus Asteraceae (dahlia and jerusalem artichoke tubers, chicory and big burdock roots) growing
on the territory of Kazakhstan.
The article discusses the methods of obtaining and application of ethyl alcohol. The results of the analysis of the
chemical composition of ethyl alcohol obtained from plants of the genus Asteraceae are presented. As a result of the
study, alcohols were obtained in different concentrations. The chemical composition of ethyl alcohol was determined
by gas chromatography. The impurity composition of ethyl alcohol obtained from various types of raw materials is
also shown.
The composition of impurities in various samples of ethanol and alcohol-containing products is considered in
detail. The results of the study were discussed, and the peculiarities of using the gas chromatography method were
shown
