Laurent Naudin, it will be remembered, devised a method of converting the aldehydes that give a bad taste and odor to impure spirits, into alcohol, through electrolytic hydrogen, the apparatus first employed being a zinc-copper couple, and afterward electrolyzers with platinum plates. His apparatus had been in operation for several months, in the distillery of Mr.
At the same time, a more pronounced odor of fatty acids and aldehydes is apparent. Still more rapidly will this oxidation occur if a thin layer of an alcoholic solution of the acid is allowed to evaporate in the air.
"With reference to the bottle of the above I have the honour to report as follows: It contains Per cent. Absolute alcohol . . . . . 39.35 Acidity expressed as acetic acid . 0.0068 Ethers expressed as acetic acid . 0.021 Aldehydes. . . . Present in small quantity. Furfural . . . . Ditto ditto Higher alcohols . . Ditto ditto "The only alcohol that can be estimated quantitatively is Ethyl Alcohol.
It has been proved by experiments on animals and observations on the human subject that alcohol taken by the pregnant woman passes freely from the maternal circulation to the foetal circulation. Féré has further shown that, by injecting alcohol and aldehydes into hen's eggs during incubation, it is possible to cause arrest of development and malformation in the chick.
