Abstract

As the one of abundant renewable resource, lignocellulosic biomass has been acknowledged for potential use to produce chemicals and biomaterials. Lignin is an amorphous, polyphenolic material arising from enzymatic dehydrogenative polymerization of three phenylpropanoid monomers coniferyl alcohol, sinapyl alcohol, and p-coumaryl alcohol. In this research, extraction of lignin from Coconut Coir Husk (CCH) was studied by thermal analysis in order to characterize their thermal behavior and to identify their constituents by the aid of their thermogravimetric curves and to determine their heat capacity by means of DSC and TGA. The FTIR was also used to determine constituents present in CCH and lignin CCH. The thermal exotherm of the lignin CCH were higher than CCH due to the removal of carbohydrates and other impurities from coir husk. In the other words, the lignin content could defer the thermal curing reactions. In addition, the TGA results shown that the removal of aliphatic sugars and increase aromatic structures can improve the thermal stability of lignin compare to CCH.
