The name given by Mulder to a peculiar fatty compound found in the fusel oil of the distilleries of Holland.
fusel oil gives a whiskey-gin flavour; and in conjunction with creasote or crude pyroligneous acid, a full whiskey flavour.
Variable quantities of fusel oil, less or greater according to the stage of ripening, exist in commercial spirits (see Spirits).
The agents used were (a) a mixture of alcohol and fusel oil, (b) alcohol and petrol (benzene).
The final process is to run the liquor through a rude charcoal filter, to rid it of most of its fusel oil.
This stuff contained 90% of pure alcohol and sometimes over 4% of fusel oil.
The latter has a specific gravity of ·8148, and is the variety produced by fermentation and present in fusel oil.
Until quite recently we have had no accurate method for the determination of fusel oil in alcohol or brandy.
Richet considers that the fusel oil contained in spirits constitutes the chief danger in the consumption of alcoholic beverages.
By this process the author has determined one part of fusel oil in ten thousand of alcohol.
