Abstract

The use of natural cellulosic fibers as materials in the reinforcements of polymer composites and sorption of oil from water, has directed more focus on acetylation than other known chemical modification methods. Cellulose can be modified by acetylation to provide a suitable and cost effective cellulose acetate which have high hydrophobic characteristics and are biodegradable. In this study, lignocellulosic samples-oil palm empty fruit bunch (OPEFB), pride of Barbados pods (POBP) and cocoa pods (CP)-with different compositions of lignin and hemicellulose, were acetylated using solvent free method. Effect of temperature on the acetylation of these samples at different reaction times were studied and used for the thermodynamic studies. Analysis of variance (ANOVA) was used to test the significance of temperature variation with weight percent gain (WPG) due to acetylation of the lignocellulosics at different reaction times. FTIR studies showed evidence of successful acetylation reaction. ANOVA test showed no statistical difference in the observed variation of WPG due to acetylation of all the lignocellulosic samples, with temperature at different reaction times. The best acetylating period for OPEFB, POBP and CP were 60, 30 and 90...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
