실험 절차

A solution of 47% (w/w) sodium hydroxide (5.5 g) is added to slurry of sorbic acid (5.6 g, 0.05 mol) in water (100 mL) at 70° C. to give a clear slightly alkaline solution. A solution of zinc chloride (3.4 g, 0.025 mol) in water (50 mL) is added and a precipitate is formed immediately. The mixture is stirred at 70° C. for further 2.5 hours. The precipitate is then filtered and dried to yield 5.5 g (76%) zinc sorbate as a fine white powder. IR absorption bands: 1521 and 1418 cm−1.
