Cyclohexane (CAS: 110-82-7) and Hexane (CAS: 110-54-3) are both widely used organic solvents in industrial and laboratory applications. While they share similar chemical properties, they differ significantly in structure, polarity, applications, and safety profile.
What is Cyclohexane CAS 110-82-7?
Cyclohexane (C6H12) is a cycloalkane composed of a single-ring structure. It is a transparent, colorless, non-polar organic liquid characterized by a mild, slightly sweet, and gasoline-like odor. It is widely used as a solvent in both industrial and laboratory settings. It is insoluble in water but soluble in methanol, ethanol, diethyl ether, acetone, benzene, petroleum ether, and carbon tetrachloride.
What is Hexane CAS 110-54-3?
Hexane C6H14 (commonly referred to as n-hexane) is a colorless, clear, highly volatile, and extremely flammable organic liquid with a petroleum-like odor. Classified as an aliphatic hydrocarbon, it is a byproduct of the crude oil refining process. It is insoluble in water and has a density lower than that of water, yet its vapor density is heavier than that of air.

Cyclohexane vs. Hexane: A Comparison of Applications
Uses of Hexane
n-Hexane finds extensive application in both industrial and consumer sectors. It is widely utilized as a cleaning solvent in industries such as printing, footwear manufacturing, automotive production, and textiles. Furthermore, it serves as a reliable cleaning agent for precision components within the military and aerospace industries.
One of the primary industrial applications of hexane lies in the oil and fat extraction industry, where it is frequently employed to extract vegetable oils from raw materials such as soybeans and other oil-bearing seeds. For the average consumer, hexane is commonly found as a constituent in blended gasoline, paint thinners, and various types of adhesives.
Uses of Cyclohexane
CAS 110-82-7 Cyclohexane is best known for its role as a key raw material in the production of nylon and other polyamide materials. Additionally, it functions as a highly effective solvent for dissolving paints, waxes, fats, resins, and other organic substances. It is also utilized in the synthesis and production of perfumes and fragrance compounds.
The applications of these two chemicals overlap in areas such as paint thinners and vegetable oil extraction, and they are sometimes used in combination during certain extraction processes. Although cyclohexane solvent has been identified as a potential substitute for hexane in the field of oil and fat extraction, the difficulty in completely removing it during the subsequent methanol washing stage complicates the feasibility of implementing a large-scale substitution in practical applications.

Health Effects
n-Hexane CAS 110-54-3
Exposure to n-hexane can lead to both acute and chronic health problems. Short-term inhalation may cause dizziness, nausea, headaches, and mild neurological reactions. Long-term exposure may trigger polyneuropathy, muscle weakness, numbness, blurred vision, and fatigue.
Cyclohexane CAS 110-82-7
Cyclohexane is toxic. Inhalation may cause headaches, dizziness, drowsiness, and impaired coordination. Ingestion may result in nausea, vomiting, and diarrhea. Repeated skin contact can cause irritation, dryness, and cracking of the skin. Eye contact may lead to pain, swelling, inflammation, tearing, and light sensitivity.
