4-Ethenylbiphenyl - Introduction
4-Vinylbiphenyl, also known as 4-Vinylbiphenyl, is an organic compound with the chemical formula C14H12. It is a colorless to yellowish liquid with a benzene ring and a vinyl functional group. The following is a description of the nature, use, preparation and safety information of 4-Vinylbiphenyl:
Nature:
1. Appearance: colorless to light yellow liquid.
2. Boiling Point: 231-233 C.
3. Density: 1.040g/cm³.
4. Solubility: Soluble in ethanol, ether and benzene and other organic solvents.
Use:
4-Vinylbiphenyl is mainly used as an intermediate in organic synthesis and is often used in the preparation of other organic compounds or polymers. It can be used to synthesize polystyrene (PS) and other related polymers, which have important applications in the plastics industry and electronics industry. In addition, it can also be used in softeners, resins, coatings, rubber and surfactants.
Method:
The preparation of 4-Vinylbiphenyl is usually obtained by reacting phenylacetylene and phenyl magnesium halide. Phenylacetylene and tetrahydrofuran were first added to the reaction vessel, then phenylmagnesium halide was added slowly, controlling the temperature and reaction time, and finally 4-Vinylbiphenyl was obtained. The reaction needs to be carried out under inert gas and appropriate safety measures, such as low temperature, ventilation and explosion-proof equipment.
Safety Information:
1. 4-Vinylbiphenyl is irritating to eyes and skin, and should be rinsed with plenty of water immediately after contact.
2. Avoid inhalation or ingestion, and operate in a well-ventilated place.
3. Avoid contact with fire, away from high temperature and sparks.
4. If necessary, should wear appropriate protective equipment, such as gloves, protective glasses and protective clothing.
5. If splashed into eyes or swallowed, seek medical attention immediately.
This information is for reference. When using or handling the compound, please refer to the relevant safety technical instructions and operating instructions.
