To Obtain Chloral

Place an- ether should have a specific gravity of .750. and keep it in a well-stoppered bottle.

This hydrous alcohol in a tubulated retort, and pass dry chlorine gas through it, at first in the alcohol at first with the acid, and as soon It is recommended to mix only a portion of the cold, but afterwards with the application as it reaches boiling point (about 280° Fahr.), of a gentle heat. As soon as the chlorine add the remainder only fast enough to repasses undecomposed through the liquor at place the fluid as it distills over; also not to the boiling temperature, the process is com- allow the heat to exceed 286°.

Another method is, to heat the sulphuric 4286. To Find the Percentage of acid to 280°, and then introduce the alcohol Ether in a Mixture of Ether and Alin a fine stream, by means of a tube with a cohol. By ascertaining the specific gravity fine lower orifice, introduced through a cork at 60° Fahr. of a mixture of ether and alcohol, fitted to the mouth of the retort; a ther- the following table will give the percentage mometer being adjusted in a similar manner, of absolute ether contained in the mixture: so that its bulb is immersed in the contents of the retort. By this means the danger of the heat rising above 286° is obviated.
