Overview
1,8-Octanediol is an organic diol featuring hydroxyl groups at both ends of an eight-carbon chain. As a linear aliphatic diol, it serves as a versatile building block in industrial chemistry. Its balanced hydrophobicity and reactivity make it valuable for synthesizing polymers and specialty chemicals. Primarily produced through catalytic hydrogenation of octanedioic acid derivatives, it is commercially available in high purity grades (≥98%). The compound is favored for its predictable reactivity and compatibility with polycondensation reactions.
Physical and Chemical Properties
This diol exhibits typical alcohol characteristics, including hydrogen bonding capability and moderate polarity. Its crystalline form melts at 61-63°C, transitioning to a viscous liquid at higher temperatures. The hydroxyl groups participate in esterification and etherification reactions. Solubility profiles show compatibility with water, ethanol, and acetone, though it has limited solubility in nonpolar solvents. Its stability under ambient conditions makes it suitable for long-term storage when protected from moisture and oxidizers.
Main Applications
In polymer chemistry, 1,8-octanediol acts as a chain extender for polyurethanes and a monomer for biodegradable polyesters. It contributes flexibility and hydrolytic stability to resulting materials. The lubricant industry utilizes it as a base for synthetic esters with high thermal stability. Cosmetic formulations employ this diol as a non-irritating humectant and viscosity modifier. Emerging applications include its use in bio-based plastics and as a precursor for pharmaceutical intermediates.
Safety and Storage
Classified as a low-hazard substance, 1,8-octanediol requires standard laboratory precautions. Skin contact may cause mild irritation—gloves and goggles are advised during handling. No significant vapor pressure exists at room temperature, but dust formation should be minimized. Storage recommendations include airtight containers in cool (below 30°C), dry environments. Incompatible with strong oxidizers; keep away from heat sources. Shelf life typically exceeds two years when stored properly.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with analytical certificates (CoA) confirming purity and moisture content. Technical grade (98%) suffices for most applications, while pharmaceutical grades command premium pricing. Bulk shipments often use polyethylene-lined steel drums. Key procurement considerations include batch consistency, logistics compatibility (non-hazardous classification), and supplier responsiveness to custom specifications. Asian and European manufacturers dominate production, with lead times of 2-4 weeks common for spot orders.
