Product Description Product Description Name(E,E,E,E)-SqualeneSynonymstrans-Squalene; (all-E)-2,6,10,15,19,23-Hexamethyl-2,6,10,14,18,22-tetracosahexaene Molecular Structure Molecular FormulaC30H50Molecular Weight410.72CAS Registry Number111-02-4EINECS203-826-1 PropertiesDensity0.858Melting point-75 oCBoiling point285 oC (25 mmHg)Refractive index1.4945-1.4965Water solubility<0.1 g/100 mL at 19 oC Main Uses: Properties: Appearance: Trans-squalene is usually a colorless to light yellow liquid. Density: Relatively small density, about 0.84 g/cm3. Solubility: It is soluble in common organic solvents and reacts with some polycyclic aromatic hydrocarbons.Use: lubricating oil additive: Trans-squalene can be used as an additive in synthetic lubricating oil to improve the viscosity index and oxidation resistance of lubricating oil.Preparation Method: Trans-squalene is usually prepared by the following steps: decyne is produced to octadecyl bromide by a trans-selective reduction reaction. The cyclopentyl compound was obtained by the cycloamylated reaction between the bromide and cyclohexene. In the presence of a metal catalyst (such as palladium), the olefin is translocated to form trans-squalene.
