Ethanol vapors quickly degrades (breaks down) in the air and has a half-life of five (5) days. Note that a half-life is the amount of time a product takes to break down from the original amount of the product to half the amount.
The half-life of alcohol is four to five hours. A half-life is how long it takes for your body to get rid of half of it. But you need about five half-lives to get rid of alcohol completely. So, it takes about 25 hours for your body to clear all the alcohol.
Most of the ethanol in the body is broken down in the liver by an enzyme called alcohol dehydrogenase (ADH), which transforms ethanol into a toxic compound called acetaldehyde (CH3CHO), a known carcinogen.
This ethanol degradation pathway begins with conversion of ethanol to acetaldehyde by peroxisomal catalase [SALWAYJG2002]. The resulting acetaldehyde passes from the peroxisome to the cytoplasm and into the mitochondrial compartment where it is converted to acetate (by mitochondrial aldehyde dehydrogenase).
Alcohol is predominantly broken down in the liver through the actions of an enzyme called alcohol dehydrogenase. On average, the liver can metabolize 1 standard drink per hour for men, or about 0.015g/100mL/hour (i.e., a reduction of blood alcohol level, or BAC, by 0.015 per hour).
More than 90% of alcohol is eliminated by the liver; 2-5% is excreted unchanged in urine, sweat, or breath.

Neutralized ethanol
Ethanol for analytic purposes is said to be neutralized when potassium or sodium hydroxide is added to ethanol containing a pH indicator, such phenolphthalein, until its color begins to turn. The solution can then be used in a titration to determine the pH of a test solution.
Fuels which contain ethanol are bad for classic cars for a number of reasons, including: Ethanol is “hygroscopic”, meaning it absorbs moisture. This moisture can condense in the fuel tank and cause components to rust, especially when the car is stored for long periods.
Ethanol: Contains significantly less energy per gallon than gasoline. Is hygroscopic, meaning it absorbs water out of the air, which means it can damage engines due to excess water content if not handled carefully.
While unopened alcohol has an almost-indefinite shelf life, opened liquor does, in fact, expire. They won't spoil in the same way that milk does, but liquors lose their flavor, coloring, and potency over time, leading to undesirable drinks for your customers.
Suffice to say, ethanol evaporates quite rapidly with respect to water due to its relatively low specific heat capacity and high vapor pressure.
Ethanol is the only type of alcohol that can be safely consumed by humans – in the form of alcohol beverages, that is. Pure ethanol is toxic and can cause comas or even death. Other types of alcohol, such as isopropyl alcohol (IPA) and butyl alcohol, are highly toxic and cannot be consumed in any way.
Conclusions: 70% alcohol was stable at least for 7 days in cotton jars, at least for 60 days in opened bottes and at least for 360 days in unopened bottles when stored at either room temperature or ambient temperature. While 70% alcohol in forceps jars was stable at least for 3 days when stored at room temperature and ...
Regular gasoline has a shelf life of three to six months, while diesel can last up to a year before it begins to degrade. On the other hand, organic-based Ethanol can lose its combustibility in just one to three months due to oxidation and evaporation.
“When you look at the chemical compositions of ethanol and gasoline…. gasoline is definitely a more dense fuel in terms of energy that you're going to get per pound. So it does more efficiently. You're going to get more miles per gallon out of gasoline than you are out of ethanol most of the time.”
One disadvantage of ethanol fuel is that it has been reported to cause engine burns and corrosion. To be able to utilize it in a more productive way, researchers are looking to convert it into hydrogen form, which should uplift it as a formidable alternative source of fuel.
Ethanol can cause several types of damage to the engine in your vehicle. Your vehicle's fuel intake components can be damaged. In addition, ethanol can cause damage to the fuel pump in your vehicle. These repairs and replacements can range from a few hundred dollars to more than $1,000 to take care of properly.
As a solvent, ethanol attacks both the metallic and rubber based fuels lines, and other fuel system components. Ethanol also has an affinity to water that can result in corrosion of fuel tanks and fuel lines. Rust resulting from this corrosion can ultimately block the fuel supply rendering the engine inoperable.
Ethanol is more soluble in water than it is in gasoline. Therefore, if you add water to the gasoline and vigorously shake it, the ethanol will attach itself to the water. After it sits for a while, the gasoline and water/ethanol will make 2 distinct layers, and you can drain off the ethanol/water in a variety of ways.
If you are considering ethanol-free gas, there are a few reasons why it is superior. Here are a few ways ethanol-free gas is more ideal for your vehicle: It provides better fuel mileage. It's cleaner for the engine.
It protects against ethanol damage by providing a protective coating on ALL the metal parts of the entire fuel system and combustion chamber, even when the engine is not running.
Heavy drinking takes a toll on the liver, and can lead to a variety of problems and liver inflammations including: Steatosis, or fatty liver.
The liver is the primary organ responsible for the detoxification of alcohol.
