Abstract—Furfural was prepared from corn cobs available locally in this study. The process consisted of crushed corn cobs, sulfuric acid and salt mixture. The mixture was heated to about 120
oC for about 2 hours to extract furfural water solution from the mixture. From the furfural water system, furfural was extracted by using ether. Ether extracted furfural from the furfural water system. As ether has low boiling point so furfural could be recovered from ether by simply heating the solution to about 33
oC. Results suggest that percentage yield of furfural could be increased by increasing the concentration of sulfuric acid.
Index Terms—Corn cobs, extraction, furfural.
