Overview
High-purity ethylcyclohexane is a saturated alicyclic hydrocarbon derived from cyclohexane. It is widely used in industrial applications due to its solvent properties and chemical stability. The high-purity grade (typically ≥99%) is essential for specialized uses where impurities could interfere with reactions or end-product quality. As a non-polar solvent, it is particularly valued in formulations requiring low reactivity and high volatility. Its production involves catalytic hydrogenation of ethylbenzene or other petrochemical processes, followed by rigorous distillation to achieve the desired purity.
Physical and Chemical Properties
Ethylcyclohexane is a colorless liquid with a mild, gasoline-like odor. Its low density (0.788 g/cm³) and boiling point (131-132°C) make it suitable for applications requiring rapid evaporation. The compound is chemically stable under standard conditions but reacts with strong oxidizing agents. Notably insoluble in water, it forms azeotropes with alcohols and other organic solvents. Its vapor pressure (10 mmHg at 25°C) and flash point (18°C) classify it as a highly flammable liquid, necessitating careful handling. The freezing point of -111°C allows for use in low-temperature applications without solidification.
Main Applications
In industrial settings, high-purity ethylcyclohexane serves primarily as a solvent for resins, waxes, and rubber compounds. Its ability to dissolve non-polar substances makes it valuable in adhesive formulations and coating systems. The chemical industry utilizes it as an intermediate in synthesizing more complex cyclohexane derivatives. Specialty applications include use as a calibration standard in chromatography and as a component in jet fuel research due to its combustion characteristics. Recent developments explore its potential as a green solvent alternative in certain extraction processes.
Safety and Storage
As a flammable liquid, ethylcyclohexane requires storage in approved safety cans or grounded metal containers away from heat and ignition sources. Proper ventilation is essential to prevent vapor accumulation, which can form explosive mixtures with air. Personal protective equipment (PPE) including chemical goggles, gloves, and vapor respirators should be used when handling. In case of spills, absorb with inert material and prevent entry into waterways. The material safety data sheet (MSDS) should always be consulted for specific first aid measures and firefighting protocols involving this hydrocarbon.
B2B Procurement Guide
When sourcing high-purity ethylcyclohexane, buyers should prioritize suppliers with ISO certification and batch-specific analysis certificates. Key specifications to verify include purity (typically 99-99.9%), water content (<0.1%), and absence of heavy metals. Packaging options range from 200L steel drums to bulk isotanks for large-volume users. Just-in-time delivery may be preferable due to the compound's flammability. Consider requesting samples for in-house testing before large orders, particularly for sensitive applications like pharmaceutical intermediates or electronic cleaning processes.
