What are Ethanol Plants?

Industrial ethanol is generally a colorless transparent liquid, which is flammable and volatile, and has a slightly aromatic odor. It is mainly used for cleaning in printing plants and electronics plants. It cannot be used as medical alcohol.

Basic information on industrial ethanol

Industrial alcohol of the same name. ^[1]

Industrial alcohol is the alcohol used in industry, also known as denatured alcohol and industrial fire alcohol.

Industrial alcohol contains 96% ethanol and 1% methanol. The purity of industrial alcohol is generally 97% and 99%.

Industrial ethanol is soluble in water, methanol, ether and chloroform. Can dissolve many organics and several inorganics. It is hygroscopic and can form an azeotropic mixture with water. It reacts violently with chromic acid, calcium hypochlorite, hydrogen peroxide, nitric acid, platinum nitrate, peroxorate and oxidant, and there is a danger of explosion. Volatile, easy to burn, light blue flame. Vapor and air form an explosive mixture with an explosion limit of 4.3-19.0% (volume).

Industrial ethanol use

Generally, 99% grade industrial alcohol is a product used by six-color four-color and three-color four-color printing presses for water. Use with printing fluid. And 97% of industrial alcohol is used in electronics factory cleaning, and the effect is good. ^[1]

Industrial ethanol poisoning properties

Industrial alcohol cannot be used for disinfection of the human body, because methanol can cause poisoning, and it will be partially absorbed by the skin for disinfection of the skin. After the poisoning, it can cause blindness and even death! ^[1]

As the active ingredient of industrial alcohol and edible wine is ethanol, it is also used by some illegal merchants to make edible wine. This kind of "wine" is poisoned by methanol after being drunk, so the liquor blended with industrial alcohol is also called "poisonous liquor".

Methanol is highly toxic and has the greatest impact on the nervous system and blood system of the human body. It can cause toxic reactions when ingested through the digestive tract, respiratory tract, or skin. Methanol vapor can damage human respiratory tract mucosa and vision. The symptoms of acute poisoning are: headache, nausea, stomach pain, fatigue, blurred vision and even blindness, and then difficulty breathing, eventually leading to paralysis of the respiratory center and death. Chronic poisoning reactions include: dizziness, lethargy, headache, tinnitus, loss of vigor, and digestive disorders. A poisoning reaction will occur if the amount of methanol intake exceeds 4 grams. If you take a small cup of more than 10 grams by mistake, you can cause blindness in the eyes and cause death if you drink a large amount. The lethal dose is more than 30 ml. Methanol is not easily excreted in the body, it will accumulate, and the formaldehyde and formic acid oxidized in the body are also toxic. In a methanol production plant, relevant Chinese authorities have stipulated that the allowable methanol concentration in the air is 50 mg / m ^3. Work on site with methanol gas must wear a gas mask, and the waste water must be treated before being discharged. The allowable content is less than 200 mg / L.

The poisoning mechanism of methanol is that methanol is metabolized by the human body to produce formaldehyde and formic acid (commonly known as formic acid), which then harms the human body. Common symptoms include drunkenness, headaches, nausea, vomiting, and blurred vision a few hours later. In severe cases, blindness can lead to death. The cause of blindness is that formic acid, a metabolite of methanol, accumulates in the eye area and destroys visual nerve cells. Brain nerves are also damaged, causing permanent damage. After formic acid enters the blood, it will make the tissue more and more acidic, damage the kidneys and cause kidney failure. Methanol poisoning can usually be detoxified with ethanol. The principle is that methanol itself is non-toxic and metabolites are toxic, so it can be detoxified by inhibiting metabolism. Methanol and ethanol are the same enzymes in the body's metabolism, and this enzyme has more affinity with ethanol. Therefore, those who are poisoned by methanol can relieve the metabolism of methanol by drinking hard alcohol (alcohol content is usually above 60 degrees), and then excrete it. Formic acid, which has been metabolized by methanol, can be neutralized by taking baking soda (sodium bicarbonate).

Industrial ethanol network terminology

It is also used on the Internet. Because industrial alcohol contains methanol, it is used as "methanol". Usually used to describe those who are pure in appearance but very dark in heart.
