gas chromatography (GC) (3) HPLC (3) Manufacturer Name. (The boiling point and freezing point of benzene are 80.1°C and 5.5°C, respectively.) Friedel-Crafts acylation of naphthalene using benzoyl chloride, catalyzed 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]. For example, if a given volume of solvent can hold 6 g of solid in solution at its (the liquid’s) boiling point and only 0.5 g of solid in solution at room temperature, then 6.0 – 0.5 = 5.5 g of solid can be recovered by crystallization from this volume of solvent. 3.
