In this research hydroxyl methyl furfural (HMF) resin, was developed from cellulosic glucose as a precursor from finely powdered greens and fruit peels. The HMF was synthesised from glucose in DMSO after hydrolysis and dehydration using HCl catalyst. Further extraction of HMF resin was accomplished using a mixture of 2 mL of 2-butanol, 2 mL of 50% of NaCl solution and 1 mL of tetrahydrofuran (THF)in the HMF synthesised solution. The HMF obtained was characterised by NMR and FTIR-ATR that confirmed the presence of HMF. The crude HMF resin acquired was purified by crystallization to increase the conversion of HMF resin from 51–92%. The ISO848 boiling test exhibited that resin has high moisture resistance and bond strength in HMF wood composite. The SEM morphological studies proved of no voids. The HMF/Wood composite tensile strength, according to ASTM D 7031-04demonstrated good strength (21.5MPa) comparable to other phenolic composites. |
