How is the following reaction carried out ?
A mixture of: Biphenyl and 2-Naphthol Dissolved in diethyl etil Add an aqueous and basic solution of NaOH then stir and separate the phases salt (cojugated base) dissolved in water kaqueous phase) of alkaline pH. lower phase dissolved in diethyl ether (organic phase).contains water residues. upper phase Magnesium sulfate is added anhydrous (MgS) to dry It is acidified with 50% HCI to protonate the conjugate base which is insoluble in water it is filtered through a Büchner by suction dissolved in diethyl ether and dry 1) is filtered by gravity (or decanted) 2) the solvent is evaporated (diethyl ether) heating on the sand bath in the extractor it is dried at 85-90 * C Acid component: pure and its solid state Neutral component: pure and in lilquid state
