Molecular characteristics of Salix cheilophila chemical components

Salix cheilophila plays a role in sand control. However, due to the lack of systematic and in-depth analysis on the chemical composition of Salix chei lophila, it is difficult to develop higher-value products, resulting in low efficiency or even outright abandonment. In this paper, the components of Salix cheilophila and its change rule before/after extraction were introduced, and the thermal loss rules and pyrolysis properties of Salix cheilophila were also explained. The analytic result of FTIR further confirmed that: (1) the Salix cheilophila contains components including esters, aldehydes, alcohols and ethers, etc., (2) the organic solvent extraction does not made compound groups of Salix cheilophila significantly changed. There are four obvious stages in thermal loss treatment of Salix cheilophila. During thermal loss treatment, three critical turning points of temperature (44°C, 78°C and 219°C) were observed, accompanied by significantly chemical changes such as macromolecule pyrolyzed into small volatile molecules. The pyrolysis products of Salix cheilophila extractive including esters, acid, alcohols, aldehyde, ethers, alkene, ammonium, anhydride, phenols, ketone, furans and heterocyclic compounds. There were quite differences among properties and functions of the components. And thus the application prospects were also significantly different.
