The determination of ethanol from the distillate was conducted through the flammability test, which resulted to 45 ml after the needed computations, it was measured that the percent ethanol was 30% and the percent loss was 26. For centuries ethyl alcohol has been ubiquitous amongst cultures the various properties of alcoholic beverages have contributed to their longstanding existence, many of which stem from its psychoactive properties the quantity of alcohol in a particular beverage becomes important in production, distribution and consumption of an alcoholic product. Gas chromatography had been widely used in determination of the alcohol in foods and beverages either for scientific research or routine analysis in the industry (gonzaâlez-arjona et al, 1999 lachenmeier et al,2008) headspace sampling has shown to be a simple, rapid, solvent less, and reliable technique.
Prepared by diluting 200-proof ethanol (rossville gold shield) with distilled water to cover the range 6 to 20% (v/v) ethanol pure ethanol and distilled water were chosen to minimize the possibility of non- ethanol components interfering in determination of the ethanol content of the standards.
