What are the components of gasoline, the main components of gasoline

The main component is C 4 C 12 hydrocarbons, which are one of the mixed hydrocarbon articles. It is a colorless or yellowish, volatile and flammable liquid with a special odor.

The composition of gasoline is more complex, mainly alkanes, from C4 to C12, of which C5 to C9 are the main ones. The composition of various gasoline is different, so their physical and chemical constants are not the same, there is a certain amplitude, the composition of gasoline is more complex, mainly alkanes, from carbon four to carbon twelve, of which carbon five to carbon nine are the main. The composition of various gasolines is different, so their physical and chemical constants are also different, and there is a certain amplitude, such as:

The boiling point is 40 200, the flash point is -58 10, and the specific gravity is, **The limit is about.

The appearance of gasoline is generally a water-white transparent liquid, the density is generally between, there is a special aromatic smell of gasoline, and the distillation range is generally 30 to 180 220

The main components of gasoline are C4 and C12 aliphatic hydrocarbons and cyclic hydrocarbons, and contain small amounts of aromatic hydrocarbons and sulfides.

The main components of gasoline are C4 and C12 hydrocarbons, which are one of the mixed hydrocarbon items.

The main components of gasoline are C4 and C12 hydrocarbons, which are one of the mixed hydrocarbon items. It is a colorless or yellowish, volatile and flammable liquid.

It has a special odor. Gasoline is insoluble in water, soluble in benzene, carbon disulfide.

and alcohol. The composition of gasoline is more complex, mainly alkanes.

From C4 to C12, of which C5 to C9 are the mainstay.

The composition of various gasolines is different, so their physicochemical constants are also different, and there is a certain amplitude, such as: the boiling point is 40 200, the flash point is 58 10, and the specific gravity is.

Uses of gasoline

According to the use, it can be divided into three categories: aviation gasoline, vehicle gasoline, and solvent gasoline. It is mainly used as fuel for gasoline engines, and is widely used in automobiles, motorcycles, speedboats, and helicopters.

Aircraft for agriculture and forestry, etc. Solvent gasoline is used in rubber, paint, grease, spices and other industries, gasoline can also dissolve oil stains, etc., water can not dissolve substances, can play a role in cleaning oil stains.

As an organic solution, gasoline can also be used as an extractant, and is currently used as an extractant, and is most widely used as the mainstream production technology of soybean oil in China.

Leaching oil technology. The operation method of leaching oil technology is as follows: soak soybeans in No. 6 light gasoline, then squeeze oil, and then form soybean edible oil after a series of processing.

The composition of gasoline is explained as follows:

Gasoline is a volatile and flammable hydrocarbon mixture liquid that is fractionated and cracked from petroleum, and can be used as fuel. The appearance is a transparent liquid, flammable, with a distillation range of 30 to 220, the main components are C5 C12 aliphatic hydrocarbons and naphthenes, as well as a certain amount of aromatic hydrocarbons, and gasoline has a high octane number (anti-knock combustion).

And according to the octane number is divided into 89, 90, 92, 93, 95, 97, 98 and other grades, from January 2012, gasoline grades 90, 93, 97 revised to 89, 92, 95.

On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) released a preliminary list of carcinogens, and gasoline was included in the list of category 2b carcinogens.

The uses and hazards of gasoline

Gasoline is the fuel of various engines, and many cars use gasoline invisibly. Many major vehicles also use gasoline as a power fuel. There are three brands of gasoline in China, namely 90 gasoline, 93 gasoline and 97 gasoline.

The choice of gasoline brand depends on the different vehicle and engine situation.

Gasoline is harmful to a person's health. Generally, after inhaling or consuming gasoline, chronic poisoning will occur, and severe cases will lead to acute poisoning. Gasoline is a narcotic poison that has an anesthetic effect on the central nervous system of the human body.

So when using gasoline, be sure to pay attention to safety. After accidentally getting gasoline on your hands, you should clean it up in time to reduce the damage of gasoline to **, and your clothes should also be washed and dried in time.

The main components of gasoline are C5, C12 aliphatic hydrocarbons and naphthenic hydrocarbons.

The English name of gasoline is gasoline, the appearance is a transparent liquid, flammable, the distillation range is 30 to 220, the main components are C5 C12 aliphatic hydrocarbons and naphthenic hydrocarbons, as well as a certain amount of aromatic hydrocarbons, gasoline has a high octane number (anti-knock combustion performance), and according to the octane number is divided into 90, 93, 95, 97 and other grades.

Gasoline is prepared by blending different gasoline components such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining with high-octane number components, which are mainly used as fuel for automobile ignition internal combustion engines.

Development History:

In the mid-19th century, the importance of gasoline was not yet recognized, and kerosene for lighting lamps was used in large quantities. Petroleum refining at that time relied on a simple distillation process to separate the components of the oil with different boiling points. The kerosene component has a high boiling point, is safe to use when lit, and becomes the main product of **refining, while gasoline and other components are often burned as fuel.

In the mid-to-late 19th century, the internal combustion engine that used gasoline was created, and in 1886, the gasoline engine was successfully operated as a vehicle power, and the importance of gasoline increased day by day. However, using the distillation method, only 20% of the gasoline can be extracted from **.

In 1911, the Standard Oil Company of the United States solved the problem of low gasoline yield, and adopted the thermal cracking process invented by William Burton and Robert Hamfries to heat crack heavy gas oil into light gasoline and other fractions, thereby improving the overall gasoline yield, and the thermal cracking process was granted a U.S. patent in 1913.
