Alkenes, C6-12 alpha- - Introduction
Alkenes are a class of organic compounds containing carbon-carbon double bonds. The C6-12 alpha indicates that the carbon chain length in such compounds is between six and twelve, and the double bond is at the opposite end of the chain (alpha position).
The nature of Alkenes:
1. Physical properties: generally colorless liquid or gas, with low boiling point and solubility.
2. Chemical properties: often occur addition reaction, such as with water to generate alcohol, and halogen to generate alkyl halide. It can also be polymerized into polymer materials, such as polyethylene and polypropylene.
Use of Alkenes:
1. Industrial use: used to prepare polymers, such as polyethylene and polypropylene; As solvents and coatings; Used to synthesize chemicals, such as alcohols and carboxylic acids.
2. Drug and pharmaceutical field: as an active ingredient or synthetic intermediate in drugs.
Preparation Method:
1. There are many methods for forming carbon-carbon double bonds, and common methods include dehydration of alcohols or ketones, for example, ethylene can be obtained by dehydration of ethanol; Olefins can also be obtained by hydrogenation of olefins or reduction of aldehydes and ketones.
2. In the laboratory, Olefins with double bonds can be obtained through acid-catalyzed dehydration reactions.
Safety Information:
1. Alkenes are flammable and should be kept away from open flames and high temperatures.
2. Long-term exposure to high concentrations of olefin vapor may cause irritation and damage to the respiratory system and skin. Therefore, appropriate protective measures should be taken during operation, such as wearing protective gloves and respirators.
3. In the storage and handling of olefins, should follow the appropriate safety procedures, to ensure that the storage container is well sealed, away from the fire and oxidant.
