Thermal Nalysis of Lignin

  • Chapter
Thermal Analysis

Abstract

Differential thermal analysis of lignin combined with other methods of investigation leads to the conclusion that the temperatures of endo- and exothermic effects of lignin depend on the quantitative ratio of separate structural bonde in a given preparation resulting from the method of lignin isolation from wood. The lignins isolated with concentrated sulphuric acid is the most thermostable. The struotureof coniferous lignin preparations is more thermostable than that of deciduous ones. The temperature ranges of thermostability of the main lignin structural bonds and the free radical mechanism of their destruction have been established.
