In some cases, unusually ellectual condensing arrangements are required, as in themanufacture of Etiikr, Ciilokofoum, Bisulphide of Caubon, and Bichloride of Carbon. In others higher temperatures are necessary, as in the distillation of sulphuric acid. When the liquids to be distilled are acid, or otherwise corrosive, great care has to betaken especially that the worm or other condenser is of a material not acted upon by theacid. See Acetic Acid and Sulphuric Acid. The term distillation is sometimes applied to cases of the volatilization and subsequentcondensation of the metals either in their preparation or purification. In cases like mercury, potassium, and sodium, where they are conden
