Overview
2-Furaldehyde, commonly known as furfural, is an important industrial chemical derived from renewable biomass sources such as corn cobs, oat hulls, and sugarcane bagasse. It is a versatile aldehyde with a reactive furan ring, making it a valuable building block for a wide range of synthetic products.

Applications

• Petroleum refining: Used as a selective solvent for the extraction of aromatic hydrocarbons from lubricating oils and diesel fuels, improving viscosity index and oxidation stability.

• Synthetic resins: Key raw material for furan resins, phenolic resins, and other thermosetting polymers used in foundry sand binders, corrosion-resistant coatings, and adhesives.

• Insulation materials: Intermediate for the production of electrical insulating varnishes and laminates.

• Nylon and fibers: Precursor for the synthesis of nylon-6,6 and other polyamides.

• Coatings and paints: Component in specialty coatings requiring chemical and thermal resistance.

• Pharmaceuticals and fine chemicals: Starting material for the synthesis of drugs, fungicides, and various organic compounds (e.g., furfuryl alcohol, tetrahydrofuran, and derivatives).

Key Benefits

• Renewable origin – reduces dependence on petrochemical feedstocks.

• High reactivity – allows diverse chemical transformations.

• Good selectivity in extraction processes.

• Biodegradable and environmentally compatible.

Recommended Usage
As a solvent in refining, typical concentrations range from 5 to 20 percent depending on feedstock. For resin synthesis, dosage varies according to formulation requirements.

Safety and Handling

• Flammable liquid; keep away from ignition sources and oxidizers.

• Harmful if swallowed or inhaled; may cause skin and eye irritation.

• Use with adequate ventilation; wear personal protective equipment (gloves, goggles, protective clothing).

• Store in a cool, dry, well-ventilated area, away from strong acids and bases which may cause polymerization.

Packaging
Available in 1 L, 5 L, 20 L, and 200 L drums, as well as custom packaging upon request.

Storage and Shelf Life
Store in tightly sealed containers under nitrogen if possible, as exposure to air may lead to oxidation and darkening. Shelf life is 12 months under recommended conditions.

Quality Assurance
Each batch is tested for purity (GC), water content (Karl Fischer), acid value, and color to ensure consistent quality and performance.
