Substitution at the benzene nucleus occurs by halogenation (acid alyst), nitration, sulfonation, and the Friedel-Crafts reaction. Friedel-Crafts acylation of naphthalene using benzoyl chloride, alyzed by AlCl3, must be conducted above the melting point of the mixture, or the reaction may be violent [Clar, E. et al., Tetrahedron, 1974, 30, 3296].

Tangit PVC-U Solvent Cement Tangit is a gap filling solvent cement for jointing PVC-U pipe and fittings, by creating a chemical bond. Joints made with TANGIT remain unaffected by almost all fluids for which PVC-U pipe is suitable. However, prolonged exposure of the inside joint edge to any of the following acid concentrations can cause some deterioration of the cement bonding.
