Publisher's Synopsis
Excerpt from A Dictionary of Applied Chemistry, Vol. 2 of 5
The following method has been devised for the continuous production of chloral. Chloral and its hydrate are the most volatile products of the action of chlorine on alcohol, and may therefore be removed by continuous distillation. A special apparatus is described; chlorine and chlorinated alcohol are introduced into a vessel heated in a water-bath, from which the vapours pass into a second and then into a third heated vessel. The residual chlorine is absorbed in a cylinder provided with baf?e plates. The rectifier, which also acts continuously, is provided with baf?e plates; it is fed at the middle with chloral, and at the top with sulphuric acid The final rectification is carried out as already described. The same apparatus may be used for converting chloral into chloroform (besson, Eng. Pat. 17202: us. Pat. 774151; J. Soc. Chem. Ind. 1901.
