Green route to modification of wood waste, cellulose and hemicellulose using reactive extrusion
Abstract
A large volume of wood waste is produced in timber processing industry which traditionally used inlow value applications. Here,value addition to the wood waste(Sander dust)and cellulose,hemi-cellulose isolated thereof by functionalisation using cyclic anhydrides in a solvent-free and greenreactive extrusion process is reported. The effect of extrusion temperature,catalyst and differentweight ratios of Sander dust(SD):succinic anhydride(SA)on the esterification reaction is eval-uated. The esterified products were characterised by the acid value,degree of substitution(DS),Fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM),solid state13CNMR and thermo-gravimetric analysis(TGA). Under optimum extrusion conditions,mixed esters areformed,with highest acid value obtained for succinylation of cellulose(0.122 g/g at DS of 0.350)which is two times higher compared to succinylated SD(0.059 g/g at a weight gain of 0.452)andhemicellulose(0.043 g/g at DS of 0.290). The reactivity trend for individual anhydride was:(1)SA Cellulose>SD>hemicellulose; (2) maleic anhydride(MA) SD>hemicellulose>cellulose and(3)dodecenyl succinic anhydride(DDSA) SDcellulose hemicellulose. The pendant free carboxyl groupsgenerated through functionalisation of wood waste,cellulose and hemicellulose without the presence ofpolymeric carriers will allow more tailored or targeted modification of wood-plastic composites.
