Brief Overview

 

Furfural is classified in organic compound and has chemical formula OC4H3CHO. It is a colourless oily liquid that smells like almonds. Furfural turns yellow when exposed to air. Furfural dissolves in most polar organic solvents, but is only slightly soluble in water or alkanes. When furfural is heated above 250 °C, it will be decomposed into furan and carbon monoxide and this reaction can sometimes be explosive.

 

Manufacturing Process

 

Plant materials contains polysaccharide hemicellulose, a polymer of sugars containing five carbon atoms each, when heated with sulfuric acid, undergoes hydrolysis to yield these sugars, mainly xylose. Under the same conditions of heat and acid, xylose and other five carbon sugars undergo dehydration, losing three water molecules and become furfural:

C5H10O5  C54O2 + 3 H2O



Solvent

Furfural is unusually effective as a solvent for phenolic resins. In the manufacture of abrasive wheels, brake linings and refractory products for the steel industry, furfural is known as a reactive solvent and excellent wetting agent.

 

Feedstock Industry

Furfural is an important renewable, non-petroleum based, chemical feedstock. Hydrogenation of furfural provides furfuryl alcohol (FA), which is a useful chemical intermediate and which may be further hydrogenated to tetrahydrofurfuryl alcohol (THFA). THFA is used as a non-hazardous solvent in agricultural formulations and as an adjuvant to help herbicides penetrate the leaf structure.

 

Refining of lubricating oils & decolorizing agent

Furfural has the unique property to dissolve aromatics and other unsaturated olefins. Furfural is used as a selective solvent in the refining of lubricating oils. This technology leads to production of high quality motor oil with improved temperature-viscosity properties. Aromatics, polar components, mercaptans are removed from petroleum by means of furfural extraction. Furfural can also be used as decolorizing agent to refine crude wood rosin.
