Preparation of diethyl tartrate
Finely powdered tartaric acid is shaken with rather more than its own weight of absolute alcohol, and then saturated with dry hydrochloric acid gas, the whole being well cooled with ice. The mixture is allowed to stand for at least twenty-four hours, and then the supernatant liquid poured off from the unchanged acid. The greater part of the hydrochloric acid is removed from the solution by blowing air through it. The excess of alcohol and water is then removed by distilling in vacuo from the water-bath. The residue consists chiefly of the acid ester. It is taken up with the same amount of absolute alcohol as was used previously, and the well-cooled solution again saturated with hydrochloric acid. After standing, it is treated exactly as before, and the residue, which does not distil from the water-bath, then fractionated in vacuo. After refractionation the ester forms a colourless viscous liquid which boils at 155° C at 11 mm. and 162° C at 19 mm. It solidifies on standing to a mass of colourless crystals which melt at 48° C.
