2-ETHYLNAPHTHALENE Chemical Properties,Uses,Production
Chemical Properties
colourless liquid
Uses
2-Ethylnaphthalene is a commonly used organic substance in the laboratory for hydrodealkylation reactions, energy transfer studies under varying concentrations of donor conditions and its vapour pressure in phase equilibrium cells.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as C2-ETHYLNAPHTHALENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
