Decahydronaphthalene, commonly recognized by its CAS number 91-17-8 and often referred to as decalin, stands out as a highly useful bicyclic organic compound. As a colorless liquid with a characteristic aromatic odor, it has established itself as a critical component in numerous industrial processes. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential chemical, and this guide aims to illuminate its significant properties and diverse applications.

The molecular structure of Decahydronaphthalene is derived from naphthalene through a process of complete hydrogenation, resulting in a saturated hydrocarbon. This saturation confers a greater degree of stability compared to its aromatic precursor. A key aspect of decalin is its existence as stereoisomers: cis-decahydronaphthalene and trans-decahydronaphthalene. The relative orientation of the hydrogen atoms at the ring junction determines these forms. The trans isomer, with its more thermodynamically favorable conformation, is often encountered in commercial products.

Understanding the physical properties of Decahydronaphthalene is vital for its effective utilization. It possesses a boiling point of approximately 190.9 °C at standard atmospheric pressure, and its flash point is around 57.2 °C. This relatively low flash point classifies it as a flammable liquid, necessitating careful handling and storage protocols. The density of Decahydronaphthalene is approximately 0.872 g/cm³. Its solubility characteristics are also noteworthy; it is virtually insoluble in water but demonstrates good solubility in many organic solvents, including alcohols, ethers, and hydrocarbons. This property is fundamental to its role as an industrial solvent.

The industrial applications of Decahydronaphthalene are extensive. It serves as a robust solvent for various substances, including oils, fats, waxes, resins, and certain polymers. This makes it valuable in cleaning formulations, extraction processes, and as a component in specialty coatings. Furthermore, its stability and combustion properties have led to its use as a fuel additive in certain applications. Research into decahydronaphthalene applications continues, exploring its potential in advanced materials and chemical synthesis pathways.
