| Johann Doebereiner,, a German chemist accidentally discovered furfural in 1832 when he treated sugar with sulfuric acid and manganese dioxide. |
| Two substances, furfural and glyoxal, are produced naturally in the environment as a combustion product of burned wood. |
| But we don't worry about the furfural in an apple, because the dose really is so small. |
| The aldehyde furfural, used as a solvent in petroleum refining, is manufactured from corn cobs and oat hulls by treatment with acid. |
| The liquor undergoes a process of further evaporation and fermentation to remove volatile compounds like methanol, furfural and ethanol. |
| Döbereiner also discovered the organic compound furfural and developed the separation of calcium and magnesium. |
