Ethene R1150 (Ethylene, chemical formula C2H4) is a colorless and slightly sweet gas, commonly found in the output of petroleum cracking and natural gas fields. Under normal temperature and pressure conditions, ethylene is in gaseous state, and its specific physical properties are as follows:
The physical and chemical properties of Ethene R1150 are as follows:
Physical properties of Ethene R1150:
Color and odor: Ethylene is colorless and has a slightly sweet or grassy odor.
Density: The density of ethylene is about 1.26 times that of air, so it is lighter than air and can easily diffuse in the air.
Melting point and boiling point: Since ethylene is a gas, it has no fixed melting point, but its boiling point is -103.9°C at standard atmospheric pressure (1 atm).
Solubility: Ethylene is partially soluble in water and alcohols.
Chemical properties of Ethene R1150:
Reactivity: Ethylene is highly reactive and can undergo addition reactions, making it an important basic raw material for organic synthesis.
In addition, ethylene has a wide range of industrial applications. It is not only used to synthesize many organic compounds such as plastics, rubber, synthetic fibers and pesticides, but also reacts with water to produce ethanol, or reacts with chlorine to produce vinyl chloride (an important raw material for polyvinyl chloride). At the same time, in the field of biology, ethylene also plays an important role as a plant hormone, which has a significant impact on the growth, flowering and fruit ripening process of plants.
3. Melting point and boiling point: As a gas, ethylene has no clear melting point, but its boiling point is -103.9°C at standard atmospheric pressure.
4. Solubility: Ethylene can be moderately soluble in water and alcohols, although its solubility in water is lower than that in organic solvents such as petroleum ether.
5. Odor characteristics: Ethylene has a slight sweet smell, which is similar to that of grass.
6. Chemical stability: Under normal conditions, ethylene exhibits chemical stability, but under high temperature or catalysts, it can quickly participate in various chemical reactions.
Detailed explanation of chemical properties:
Unsaturation: There is a double bond (C=C) in the ethylene molecule, which makes it highly chemically active and can undergo addition reactions, such as reacting with hydrogen or halogens.
Addition reaction: Under appropriate reaction conditions, ethylene can undergo hydrogenation reaction with hydrogen to produce ethane (C2H6); at the same time, it can also undergo addition reaction with halogens such as chlorine to produce compounds such as vinyl chloride.
Plant hormone function: Ethylene plays the role of plant hormone in the field of biology, which can promote physiological processes such as fruit ripening, leaf aging and flower withering.
Combustibility: Ethylene is a flammable gas that produces carbon dioxide and water when it reacts with oxygen.
These rich physical and chemical properties make ethylene widely used in many fields, whether it is industrial production, agricultural application or chemical experimental research.
3. Combustion reaction (oxidation reaction):
Ethylene can undergo combustion reaction in oxygen to produce carbon dioxide and water. The reaction equation is: C2H4 + 3O2 → 2CO2 + 2H2O. This reaction is quite common in the practical application of ethylene, especially in industrial synthesis and biological processes, where it plays a vital role.
