Applications

1. Furfuraldehyde thanks several large scale applications to its solubility characteristics and its easy recuperation by steam distillation. Furfuraldehyde has the unique property to dissolve aromatics and other unsaturated olefins. Today all major oil companies use furfuraldehyde as selective solvent in the refining of lubricating oils.

2. During the Second World War the purification technology of butadiene was developed in the United States for the manufacture of synthetic rubber. By extractive distillation with furfuraldehyde butadiene or isoprene can be separated from other C4 and C5hydrocarbons, respectively. reactive solvent and good wetting agent.

3. Furfuraldehyde is unusually effective as a solvent for phenolic resins. In the manufacture of abrasive wheels, brake linings and refractory products for the steel industry furfuraldehyde is known as a reactive solvent and excellent wetting agent. unique chemical feedstock for other furan derivatives.

4. However, the main outlet of furfuraldehyde is as chemical feedstock for the production of furfuryl alcohol and for other 5-membered oxygen-containing heterocycles, i.e. furan, methylfuran, acetylfuran, furfurylamine and furoic acid.
