Methanol Overview

Propylene is a gas at room temperature, colorless, odorless and slightly sweet. It is one of the basic raw materials of petrochemical industry.

Propylene can be used to produce a variety of important organic chemicals, such as acrylonitrile, propylene oxide, isopropylbenzene, chloroalkylene oxide, isopropyl alcohol, propanetriol, acetone, butanol, octanol, acrolein, acrylic acid, acrylic alcohol, acetone, glycerol, polypropylene, etc.; in the refining industry is the raw material for the production of stacked gasoline; it can also be used to produce synthetic resins, synthetic fibers, synthetic rubbers, and a variety of fine chemicals and so on. It can also be used in the fields of environmental protection, medical science and basic research.

Carbon tetra that is butane (C4H10), also known as n-butane, is two alkane hydrocarbons with the same molecular formula (C4H10) of the collective name.

Carbon tetrachloride in addition to direct use as fuel and refrigerant, a large number of organic synthetic raw materials used in the production of a variety of, such as dehydrogenation of butene and butadiene; isomerization can be isobutane; catalytic oxidation can be made of maleic anhydride, acetic acid, etc.; halogenation can be halogenated; nitration can be nitro-butane; catalytic at high temperatures can be made of carbon disulfide; water vapor conversion can be made of hydrogen.

Propane, a three-carbon alkane with the chemical formula C3H8 and the structural short form CH3CH2CH3, is usually gaseous but is usually compressed into a liquid state for transportation. Propane is mainly found in oilfield gas, natural gas, and refinery gas.

Propane is mainly used to make ethylene, propylene, oxygenates and primary nitroalkanes. It is also used as a fuel to power trains, buses, forklifts, and cabs, as well as for heating and cooking in RVs and camping.

Fuel gas is a mixture of various components, mainly hydrogen, methane, ethane, nitrogen and a small amount of carbon monoxide, propane and various hydrocarbons.

Fuel gas can be used directly as fuel for internal combustion engines, etc., and can also be used as raw material for industries such as ammonia synthesis, margarine and organic synthesis.

Liquid oxygen (often denoted by the acronym LOX or LO²) is the form of oxygen when it is in the liquid state.

Liquid oxygen has a wide range of industrial and medical uses, and it has important applications in the aerospace, submarine and gas industries.

Liquid nitrogen is nitrogen in liquid form. It is inert, colorless, odorless, non-corrosive, non-flammable, and has an extremely low temperature.

In industrial production, liquid nitrogen can be used as a deep refrigerant, and because of its chemical inertness, it can be directly contacted with biological tissues and frozen immediately without destroying the biological activity, and it can also be applied in biological and medical fields, as well as used in cryotherapy.

Oxygen, a colorless, odorless gas, the most common singlet form of the element oxygen.

(1) In the production of ammonia in the chemical industry, oxygen is mainly used in the oxidation of raw gas to intensify the process and increase fertilizer production. Further examples are: high temperature cracking of heavy oil, and gasification of pulverized coal.

(2) In the smelting process blowing with high purity oxygen, not only can reduce the carbon content of steel, but also conducive to the removal of phosphorus, sulfur, silicon and other impurities. Moreover, the heat generated in the oxidation process is sufficient to maintain the temperature required for the steelmaking process, therefore, blowing oxygen not only shortens the smelting time, but also improves the quality of steel.

(3) It can be used in medical care to supply respiration in hypoxic, low-oxygen or anaerobic environments, e.g., diving, mountaineering, high-altitude flights, cosmic voyages, and medical resuscitation.

(4) Other aspects: can be used as a flux with acetylene, propane and other flammable gases, to achieve the role of welding and cutting metal, in various industries, especially in the mechanical enterprises are widely used as a cutting is also very convenient, is the preferred method of a cutting.

Nitrogen, a monomer formed from the element nitrogen. It is a colorless and odorless inert gas at room temperature and pressure, and the industry often uses the method of fractional distillation of liquid air to obtain a large amount of nitrogen.

(1) In the chemical industry, nitrogen is mainly used as a protective gas, replacement gas, scrubbing gas and safety gas. It is also used as an important raw material for ammonia synthesis, synthetic resin and synthetic rubber. Nitrogen is a nutrient element can also be used to make fertilizer; for example: ammonium bicarbonate NH4HCO3, ammonium chloride NH4Cl, ammonium nitrate NH4NO3 and so on.

(2) Because of the chemical inertia of nitrogen, it is often used as a protective gas for bright annealing of copper tubes, processing of aluminum products and profiles, thin aluminum rolling, reflow and wave soldering, float glass production, etc.; as a food preservation gas, it can prevent some objects from being oxidized by oxygen when exposed to the air, and it can be used to fill the grain bin with nitrogen to make the grain not moldy, not germinated, and preserved for a long period of time; and it can be used as a laser gas for laser cutting machines together with high purity helium and high purity carbon dioxide. It can also be used as the laser gas of laser cutting machine together with high purity helium and high purity carbon dioxide. High purity nitrogen can also be used as carrier gas for chromatograph and other instruments.
