Production. Naphthalene is produced from either coal tar (which contains ap- proximately 10% naphthalene), by condensation and separation of coal tar from coke-oven gases, or from petroleum, by dealkylation of methylnaphthalenes. In the United States, most naphthalene was pro- duced from petroleum through the 1980s.
