hydrocarbons, C4-5-unsaturated - Introduction
C4-5 unsaturated hydrocarbon means an unsaturated hydrocarbon having 4 to 5 carbon atoms. They are organic compounds composed of the elements carbon and hydrogen.
The properties of C4-5 unsaturated hydrocarbons include the following aspects:
1. Unsaturation: They contain one or more double or triple bonds, so they are more active in structure.
2. Melting point and boiling point: its melting point and boiling point range, because of its small molecular weight, so generally exist in gaseous or liquid.
3. Reactivity: Due to the presence of unsaturated bonds, they are prone to addition reactions, oxidation reactions, etc.
C4-5 unsaturated hydrocarbons have a wide range of applications:
1. Fuel: they can be used as fuel, widely used in gas, gas, gasoline and so on.
2. Chemical raw materials: C4-5 unsaturated hydrocarbons are important raw materials for the synthesis of chemical products, such as ethylene, propylene, etc.
3. Plastic and rubber industry: They can be used to produce various plastic and rubber products, such as polyethylene, polypropylene, etc.
There are many ways to prepare C4-5 unsaturated hydrocarbons:
1. Cracking method: Through the catalytic cracking or thermal cracking of petroleum, the corresponding unsaturated hydrocarbons can be obtained.
2. Hydrogenation and dehydrogenation method: the use of hydrogen and a suitable catalyst for the reaction, under appropriate conditions can be converted into saturated hydrocarbons unsaturated hydrocarbons.
3. Alkylation method: the use of appropriate alkylating agent, the saturated hydrocarbon alkylation reaction, can get the corresponding unsaturated hydrocarbon.
Regarding safety information, the following should be noted when using and storing C4-5 unsaturated hydrocarbons:
1. Avoid contact with skin and eyes to avoid irritation and chemical burns.
2. Avoid inhalation of its vapor, because it may cause irritation and damage to the respiratory system.
3. Store away from open flame and high temperature to prevent explosion and combustion risk.
4. During use or storage, good ventilation must be maintained to avoid the accumulation of harmful gas concentrations.
