  Cocaine - Wikipedia, the free encyclopedia
Cocaine sulfate is produced by macerating coca leaves along with water that has been acidulated with sulfuric acid, or a naphtha-based solvent, like kerosene or benzene.

 HighBeam Encyclopedia - naphthol
The naphthols are position isomers, differing in the location of the hydroxyl group, -OH, on the carbon skeleton of naphthalene ; α-naphthol is 1-hydroxynaphthalene and β-naphthol is 2-hydroxynaphthalene: The naphthols have a number of similar properties.
One way in which they differ is the form of their crystals—α-naphthol crystallizes in prisms and β-naphthol in plates.
The naphthols are prepared by reacting naphthalene with sulfuric acid and hydrolyzing the resultant sulfate ester by heating it with sodium hydroxide solution.
