Overview
Furfuryl alcohol is an organic compound derived from furfural, a byproduct of agricultural waste such as corn cobs and sugarcane bagasse. It is a key intermediate in the production of furan resins and other industrial chemicals. The compound is notable for its high reactivity and versatility, making it valuable in various chemical processes. Its production involves the hydrogenation of furfural, a process that has been optimized for efficiency and environmental sustainability. Furfuryl alcohol is widely used in industries ranging from adhesives to food flavoring, owing to its unique chemical properties and relatively low toxicity.
Physical and Chemical Properties
Furfuryl alcohol is a colorless to pale yellow liquid with a faint, pleasant odor. It has a molecular weight of 98.10 g/mol and a density of 1.129 g/cm³ at 20°C. The compound is highly soluble in water and most organic solvents, which enhances its utility in various applications. Its boiling point is 171°C, and it freezes at -29°C. The alcohol is known for its high reactivity, particularly in polymerization reactions, which makes it a preferred choice for producing furan resins. Its low toxicity and biodegradability further contribute to its widespread use in industrial and consumer products.
Main Applications
Furfuryl alcohol is primarily used in the production of furan resins, which are employed in foundry binders, adhesives, and coatings. These resins are valued for their high thermal stability and resistance to chemicals, making them ideal for industrial applications. In the food industry, furfuryl alcohol is used as a flavoring agent, imparting a caramel-like aroma to products. It also serves as a solvent in the synthesis of pharmaceuticals and other fine chemicals. Additionally, its derivatives are utilized in the manufacture of corrosion inhibitors and plasticizers, further expanding its industrial relevance.
Safety and Storage
While furfuryl alcohol is considered low in toxicity, it can cause irritation upon contact with skin or eyes. Inhalation of vapors should be avoided, and adequate ventilation is necessary when handling the compound. Personal protective equipment, such as gloves and goggles, is recommended. Storage conditions should include a cool, dry, and well-ventilated area, away from oxidizing agents and sources of ignition. The compound is stable under normal conditions but can polymerize if exposed to heat or incompatible materials. Proper labeling and adherence to safety protocols are essential to prevent accidents.
B2B Procurement Guide
When procuring furfuryl alcohol, buyers should prioritize suppliers with a proven track record of reliability and quality assurance. Key factors to consider include the purity of the compound, which typically ranges from 98% to 99.5%, and compliance with industry standards such as ISO or REACH. Price fluctuations are common due to variations in raw material costs and market demand. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be evaluated. It is also advisable to request material safety data sheets (MSDS) and certificates of analysis (CoA) to ensure product quality and safety.
