Petroleum Additives1-Fluoronaphthalene CAS# 321-38-0
The main sources of 1-chloronaphthalene in the environment include industrially produced 1-chloronaphthalene; 1-chloronaphthalene produced in thermal processes and other processes (such as the chlor-alkali industry) in the presence of chlorine; in addition, it is also a by-product in the synthesis of polychlorinated biphenyls (PCBs).
Uses: Used as a solvent, for example, as an immersion liquid when measuring the refractive index of crystals under a microscope, and as a solvent for oils and fats. Used in organic synthesis. It is a gas chromatography stationary liquid (maximum operating temperature 75°C, solvents are chloroform and methanol), which can be used to separate and analyze low-level hydrocarbons and halogenated hydrocarbons, can selectively retain aromatic compounds, and can also separate xylene isomers.
