Designed for the production of synthetic rubbers, chloroprene, thermoplastic elastomers and latexes.

The fraction of normal butane is produced in a gas fractionation plant and is butane with small amounts of accompanying hydrocarbons. The normal fraction is used as a raw material for the production of butadiene and in the production of synthetic rubber, as well as for pyrolysis and other purposes.

It is used as a raw material in the production of copolymer rubbers. BBF is available in three grades:
- grade "A" represents non-condensed C4 hydrocarbons in the gas phase;
- grade "B" represents condensed C4 hydrocarbons after distillation of volatile hydrocarbons;
- grade "B" represents condensed C4 hydrocarbons produced by butadiene-1,3.

Carbamide is produced in two grades - A and B.
The first option (grade A) is used as a raw material for the production of various products:
- fibreboard (MDF);
- drugs (diuretics, sleeping pills, etc.);
- resins and adhesives;
- plastics;
- liquid reagent AdBlue;
- some products (flour, chewing gum);
- cosmetics (moisturizing creams), etc.
The second option (grade B) is intended for fertilizing crops.

Application.
Due to its low cost, ethylene glycol has found wide application in engineering.
● As a component of automotive antifreeze and brake fluids, accounting for 60% of its consumption. A mixture of 60% ethylene glycol and 40% water freezes at -49°C. Corrosion active, therefore it is used with corrosion inhibitors;
● Used as a coolant with a content of not more than 50% in heating systems (mainly private houses)
● As a coolant in the form of a solution in cars, in liquid cooling systems for computers;
● In the production of cellophane, polyurethanes and a number of other polymers. This is the second main application;
● As a solvent for dyes;
● In organic synthesis:
● as a high temperature solvent.
● to protect the carbonyl group by obtaining 1,3-dioxolane. Treatment of a substance with a carbonyl group in benzene or toluene with ethylene glycol in the presence of an acid catalyst (toluenesulfonic acid, BF3•Et2O, etc.) and azeotropic distillation of the formed water on a Dean-Stark apparatus. For example, the protection of the carbonyl group of isophorone.
1,3-dioxolanes can also be obtained by the reaction of ethylene glycol with carbonyl compounds in the presence of trimethylchlorosilane[4] or dimethylsulfate-DMF[5] complex. 1,3-dioxalane is resistant to nucleophiles and bases. The original carbonyl compound is easily regenerated in the presence of acid and water.
● As a component of the "I" fluid used to prevent flooding of aviation fuels.
● As a cryoprotectant
● To absorb water, to prevent the formation of methane hydrate (an inhibitor of hydrate formation), which clogs pipelines during offshore gas production. At ground stations, it is regenerated by drying and removing salts.
● Ethylene glycol is the raw material for the production of the explosive nitroglycol.
Ethylene glycol is also used:
● in the production of capacitors
● in the production of 1,4-dioxane
● as a heat carrier in chiller-fan coil systems
● as a component of shoe polish (1-2%)
● in glass cleaner together with isopropyl alcohol
● in cryopreservation of biological objects (in cryonics) as a cryoprotector.
● in the production of polyethylene terephthalate, the plastic of popular PET bottles.

It is used to increase the octane number in the production of motor gasoline. The addition of MTBE to motor fuels increases the efficiency of the engine, improves engine starting at low temperatures. Significantly reduces the content of CO and hydrocarbons in vehicle exhaust gases.

The percentage ratio of propane and butane in the gas mixture is not regulated by state standards and is mainly determined by the conditions of its use. At low temperatures, gas with a high content of propane is used, at higher temperatures - butane. This is due to the fact that propane retains a liquid consistency at temperatures up to -42C, and for butane this temperature is only -0.05C. In climate conditions in which the temperature of the air or the ground on which the gas containers are installed falls below -20C, technical propane-butane mixture is used, in which the proportion of propane is at least 75%. In automotive fuel, two types of mixture are also used - winter and summer. Summer mixture - about 50% propane, winter - up to 90% propane.
The use of butane in the mixture is justified by its higher combustion temperature. The use of technical propane-butane mixture is not only cost-effective, but also more environmentally friendly compared to the use of gasoline, diesel fuel or fuel oil. The cost of installing equipment on a car that uses such gas as a fuel is very quickly paid off by reducing the cost of fuel and lubricants. The environmental effect is not so noticeable to a particular consumer, but it is very important in terms of preserving the environment as a whole.

According to its properties and composition, absolute alcohol can be attributed to technical alcohols. Absolute alcohol is the most common and in demand, because, unlike ethyl alcohol, its circulation is not controlled at the legislative level. Today, absolute alcohol is actively used in various industrial sectors.
Isopropyl alcohol is a colorless liquid with a pungent alcoholic odor. Vapors of this substance are easily mixed with oxygen, forming an explosive mixture. Alcohol tends to dissolve in acetone and benzene, but it mixes with other chemical solvents in various proportions. The melting point is about -90 °C degrees, and the boiling point is over 82 °C.
Isopropyl alcohol components can form ethers and esters. This substance can dissolve a number of essential oils, alkaloids, synthetic resins and many other compounds. Dehydration of alcohol produces acetone. Also, isopropyl reacts with many oxidizing agents, in addition, the substance is aggressive to many types of rubber and plastic.

It is intended for the production of plasticizers, alkyd resins, dyes, medicines, the production of plastics, rubber products, etc.

It is used for the manufacture of pipes and fittings for gas distribution networks, as well as pressure pipes and fittings for domestic and drinking cold water supply.
Many different grades of pipe polyethylene are produced. One of the main differences between the brands of these products is in the melt flow rate.

A colorless gas with a characteristic odor.
The main industrial method of obtaining: oil refining and separation of the components of the mixture.
It is used as a raw material for the production of polymers and in other organic syntheses. Also serves as a component of some gas mixtures for welding metals.
