Description of naphth(la)ne
- Decalin (decahydronaphthalene, also known as bicyclo[4.4.0]decane), a bicyclic organic compound, is an industrial solvent. A colorless liquid with an aromatic odor, it is used as a solvent for many resins or fuel additives. It is the saturated analog of naphthalene and can be prepared from it by hydrogenation in the presence of a catalyst. Decahydronaphthalene easily forms explosive organic peroxides upon storage in the presence of air.

What is Decahydronaphthalene?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Decahydronaphthalene which has developed particularly rapidly in recent years. Do you know about Decahydronaphthalene?
- The official answer：Colorless liquid. Produced by hydrogenation of naphthalene, industrial decahydronaphthalene is a mixture of cis and trans isomers. Insoluble in water, miscible with ethanol, ether, acetone, and benzene. Similar to methanol odor, the vapor is purple. Flashpoint 57℃.
What’s the application of Decahydronaphthalene?
- It can be used as a solvent for paint, for extracting fat and wax, instead of turpentine for the manufacture of shoe polish and floor wax, and can be used as a mixture with benzene and ethanol as a fuel for internal combustion engines. Used as a liquid for refractive index determination, also used as a solvent
