Two new Acid Compounds. 141 
Art. XV.—On two new acid compounds of Chlorine, Carbon, and 
Hydrogen; by Aueustus A. Haygs. 
Amone the compounds which result from the action of chlorine on 
alcohol, there are two, whose relations to bases are such as to entitle 
them to be classed with those acid combinations, in which hydro- 
carbon neutralizes, in part, the properties of the other proximate ele- 
ment. hen pure alcohol at 32° F. is exposed to a current of 
chlorine, which has passed through a refrigerated tube in part filled 
with fragments of dry lime, there is an absorption of the gas, and 
unless suitable baths are used, an elevation of temperature is occa- 
sioned ; the rapidity of the current being diminished, a small quantity 
of alcohol will continue to absorb it for several hours. The liquid 
becomes of a greenish yellow color and, unless the agitation has 
been considerable, consists cf two portions of different densities, the 
lighter, containing more alcohol and less acid than the denser: both 
are lighter than water. If the operation is continued, globules of 
chloric ether mixed with other compounds, will separate and occupy 
a lower place. On diluting the mixture with water, a separation of 
more chloric ether takes place, other globules appear and are vola- 
tilized, with the odor of muriatic ether, as the temperature rises ; 
much muriatic acid and alcohol are also present. After decanting 
the fluid from the chloric ether and mixing it with hydrate of lime, 
it loses its acid suffocating odor and diffuses the grateful odor of 
ehlorie ether. Distilled into a cooled receiver, some chloric ether 
dissolved in alcohol is obtained. ‘The remainder consists principally 
of muriate of lime, but contains two salts which are simnltaneously 
formed, and which may be obtained by evaporation, and separated 
by crystallization. Results differing from these are under other cir- 
cumstances obtained, and will be hereafter described. When we 
substitute for the gas, a chloride of an alkaline oxide, less compli- 
eated changes occur. We may use with advantage, the mixture of 
hydrate and chloride of lime constituting bleaching powder. The 
best bleaching powder, in the market, contains ;3,°, of condensed 
chlorine. If we add to such powder, contained in a flask, its weight 
of ordinary alcohol, on mixing, the mass emits very acrid penetrating 
vapors, consisting of chloric ether mixed with one of the new acid 
compounds: the temperature gradually rises, and if more than 
ten or twelve ounces of the powder are used, violent ebullition suc-
