Structural formula of ethyl alcohol

Under ethyl alcohol of agricultural origin , also agricultural alcohol , Prima fuel , drinking alcohol or alcohol (Germany) and potable spirits called (Switzerland), refers to hard alcohol ( ethanol ) obtained by alcoholic fermentation of the agriculture produced sugar - or starch , raw materials such as fruits, grains Sugar beet, sugar cane or potatoes and then distilling the mash was obtained. It is used in pharmaceutical, cosmetic and food production. Alcohol produced synthetically from the petroleum derivative ethene as well as alcohol from non-agricultural raw materials (e.g. cellulosic ethanol ) may not be used for this.

In contrast to spirits such as grain and fruit brandies, neutral alcohol is tasteless and odorless and does not have any sensory properties in the original products.

If ethyl alcohol is to be sold untaxed and further processed for technical purposes, it must first be made inedible by denaturing (denatured ethanol, see denatured alcohol ).

Situation in Germany

This agricultural alcohol is cleaned and taxed in Germany by the federal monopoly administration; its name is then neutral alcohol .

As a rule, untaxed and purified agricultural alcohol is called monopoly fuel , or monopoly alcohol. It is used in the further processing of liqueur production and is therefore subject to the spirits regulation.

use

Ethyl alcohol can be used both for further processing in the food industry into spirits such as vodka , gin or liqueurs as well as brandy vinegar and flavors, as well as in the manufacture of pharmaceuticals, cosmetics, cleaning agents, disinfectants, antifreeze, paints or varnishes. The preservation, landscape and biotope care of numerous orchards is often only possible today through the purchase guarantee of the Federal Monopoly Administration for brandy , which purchases the alcohol from many small farms and part-time distilleries that they distill from orchards (if they cannot market fruit schnapps , corn brandy or potato schnapps ).

Earlier it was in "hard jobs" (z. B. in mining, glass industry or brickworks) drinking alcohol, ethyl alcohol diluted to drinking strength as Deputatleistung given. For this purpose, there were separate flavors and additives in drugstores or similar shops that gave the schnapps a taste.

Gasoline or ETBE denatured ethyl alcohol (biogenically produced ethanol) can be used as gasoline are used and high-octane gasoline substitute. In this form, ethyl alcohol of agricultural origin is usually referred to as bioethanol . In Germany, around 50% of the amount of biogenically produced ethanol is produced as neutral alcohol for beverages and food as well as for other technical purposes and around 50% for use as a "renewable" component of super fuel or E10 (fuel) or in pure form as ethanol -Fuel . Worldwide the ratio is around 35% to 65%.
