Dicyclopentyl ether

Updated: 2026-09-16

Overview

Dicyclopentyl ether (C10H18O) is an organic compound consisting of two cyclopentyl groups linked by an oxygen atom. It is primarily used as a high-boiling-point solvent and intermediate in chemical synthesis. The compound's stability and solubility in organic solvents make it valuable for industrial applications. First synthesized in the mid-20th century, dicyclopentyl ether is now commercially available in technical and high-purity grades. Its production typically involves the Williamson ether synthesis using cyclopentanol derivatives.

Physical and Chemical Properties

Dicyclopentyl ether is a colorless to pale yellow liquid with a mild, ether-like odor. It has a density of 0.91-0.93 g/cm³ and boils at 210-215°C, making it suitable for high-temperature applications. The compound is hydrophobic and miscible with most organic solvents but immiscible with water. Chemically, it is relatively inert under standard conditions but may react with strong oxidizing agents. Its stability and low volatility contribute to its utility as a reaction medium in organic synthesis and polymer processing.

Main Applications

The primary use of dicyclopentyl ether is as a solvent for resins, polymers, and specialty coatings. Its high boiling point allows for elevated-temperature processing without rapid evaporation. In the pharmaceutical industry, it serves as an intermediate in the synthesis of active ingredients. Additional applications include use as a lubricant additive to improve thermal stability and as a carrier fluid in industrial cleaning formulations. Its low toxicity profile (compared to alternatives like glycol ethers) makes it preferable for certain niche applications.

Safety and Storage

Dicyclopentyl ether is classified as an irritant to skin and eyes. Proper personal protective equipment (PPE), including nitrile gloves and safety goggles, should be worn during handling. Adequate ventilation is required to prevent vapor accumulation. The compound should be stored in tightly sealed containers made of stainless steel or approved plastics, away from heat and open flames. Shelf life is typically 2-3 years when stored under recommended conditions. Spills should be contained with absorbent materials and disposed of as hazardous waste.

B2B Procurement Guide

Industrial buyers should specify purity requirements (typically 95-99%) and verify the CAS number (2143-31-7) when ordering. Due to its specialized nature, dicyclopentyl ether may require custom synthesis for large-scale orders, with lead times of 4-8 weeks. Key suppliers include chemical manufacturers with ether synthesis capabilities. Pricing is volume-dependent, with discounts available for metric ton quantities. Buyers should request material safety data sheets (MSDS) and certificates of analysis (CoA) for quality assurance.
