Solvent-free esterification of wood with octanoyl chloride produced an esterified material with a weight increase of 87% and an ester content of 60%. However, a fraction of sawdust (22% of the esterified wood) was solubilized during this esterification. Chemical analyses showed that it contained essentially esterified and hydrolyzed hemicelluloses with small amount of esterified cellulose.The reactivities...
A new series of esters was prepared by esterification of 1,4:3,6-dianhydro-d-glucitol with long chain fatty acid chlorides. The experimental conditions prevented thermal degradation of the sugar and led to diesters with a high degree of purity. The final products were readily isolated and characterized by IR and NMR. Molecular modelling confirmed that the exo and endo configurations of the o-alkyl...
