Fusel oil is divided into low grade oil, intermediate oil and high grade oil, how is it divided?

Physical and chemical properties: colorless to yellow oily liquid. It has a special odor and toxicity.

Relative density. It mainly contains isoamyl alcohol, butanol, propanol and heptanol. Fusel oil is a general term for aliphatic alcohols with a carbon number greater than 2.

Higher alcohol, commonly known as fusel oil, is a monovalent alcohol with more than three carbon chains, and is the main by-product of beer fermentation, including n-propanol, isobutanol, isoamyl alcohol, active pentanol, benzene isopropanol isolated from corn alcohol fusel oil.

ethanol, etc. The high-grade alcohol forms the aroma and flavor of the beer. When the high-grade alcohol content in beer is too high, it will affect the flavor and taste of the beer, and it will "go up" after drinking and seriously affect the quality of the beer.

For example, the total high-grade alcohol content in beer is 100-150mg l for ordinary beer, and 90-110mg l for premium beer. Preparation method: a by-product of fermentation to produce alcohol.

It is also a by-product of the alcohol method for the production of butadiene. Product use: can be used as a solvent.

It can also be used as fuel, flotation agent, etc. used as spices, plasticizers and paints. Toxicity Protection:

Toxic, the highest allowable concentration in the air. Wear a gas mask at concentrations below 2% and oxygen levels above 17%. Packaging, storage and transportation:

It is packed in iron drums, 160kg per barrel, which can be shipped by train and tanker, and it should be fireproof during storage and transportation. According to the provisions of toxic substances storage and transportation. Dehydration of fusel oil:

Because fusel oil contains many low-carbon alcohols, they can form azeotropes with water, resulting in fusel oil generally containing 12% 30% water, which is an important factor affecting the purity of the extract. As a raw material, the water content of fusel oil is generally required to be less than 15%, and the content of isoamyl alcohol is more than 45%. There are four commonly used dehydration methods: quicklime reflux dehydration, 4A molecular sieve dehydration, solid salt dehydration and brine salting out dehydration.

Fusel oil impurities: crude fusel oil contains about 5% impurities, which can generally be washed with 5% (mass fraction) of sodium carbonate: and then oxidized with 2% saturated potassium permanganate.

It can remove more than 90% of impurities and colored substances.

According to the purity, and density can be divided into low-grade intermediate high-grade low-grade isoamyl alcohol, butanol, propanol and heptanol low purity, intermediate isoamyl alcohol, butanol, propanol and heptanol high point, high-grade isoamyl alcohol, butanol, propanol and heptanol highest.

It must be based on the length and structure of the carbon chain, but there are 16 components in total.

Fusel oil is a blend of oils that is made up of many different hydrocarbons, including alkanes, olefins, and aromatics. This oil is usually extracted from petroleum, but it can also be obtained from other**, such as natural gas and biomass. Oils similar to fusel oils include naphtha, light diesel, and heavy diesel, among others.

These oils are also derived from petroleum, but they differ slightly in composition and properties. For example, naphtha is mainly composed of alkanes, while light and heavy diesel contains more olefins and aromatic hydrocarbons. Overall, fusel oil is a very common petroleum product that can be used in a wide range of applications, including as fuels, lubricants and chemical feedstocks.

In the field of industry and transportation, fusel oil is an indispensable energy source**, which is of great significance to our life and economic development.

Summary. Fusel oil is the same oil as diesel and light diesel.

Fusel oil is the same oil as diesel and light diesel.

Fusel oil is a kind of fuel oil processed from petroleum, which is mainly used in the combustion of diesel engines. In China, fusel oil is commonly referred to as No. 0 diesel, also known as light diesel oil, whose main components are hydrocarbons, including alkanes, naphthenes, and aromatic hydrocarbons. Diesel and light diesel have a high ignition point, good combustion performance and economy, so they are widely used in various diesel machinery and equipment, such as generator sets, agricultural machinery, construction machinery, etc.

In general, fusel oil, diesel, and light diesel oil refer to the same type of fuel oil, but there are different names and specifications in different regions and industries.

Hello dear dear, fusel oil is mainly a mixed alcohol fuel, which is different from the sedan oil and diesel fuel prepared by the cracking of petroleum in the balance system, it is made of methanol, ethanol, isobutanol and other alcohols. Therefore, fusel oil does not belong to the category of traditional fuels, it is quite different from other types of fuels, and it is not very easy to be called the same oil as a certain fuel However, if fusel oil is compared with similar renewable energy fuels, it can be classified with biodiesel, bioethanol, biomethanol, etc., which are all renewable energy fuels and are more environmentally friendly. These renewable energy fuels help to reduce dependence on fossil fuels, and the energy saving and environmental protection effects are obvious<>
