3-Buten-1-ylbenzene(CAS: 768-56-9)

3-Buten-1-ylbenzene (CAS: 768-56-9) is a colorless liquid with a molecular weight of approximately 130.22 g/mol. It has a moderate solubility in water (0.5 g/100 mL at 20°C) and is soluble in most organic solvents. Chemically, it is relatively stable but can undergo substitution and addition reactions. It is a volatile compound with a boiling point of 153-155°C and a flash point of 77°C.

3-Buten-1-ylbenzene can be synthesized via a Friedel-Crafts alkylation reaction where 1-butenyl chloride is introduced into benzene in the presence of a Lewis acid catalyst, such as aluminum chloride. Alternatively, it can be produced by the alkylation of toluene with 1-butyne using a heterogeneous catalyst like platinum on a carrier. The yield and selectivity can be controlled by adjusting the reaction conditions and catalyst type.

3-Buten-1-ylbenzene (CAS: 768-56-9) is primarily used in the pharmaceutical industry for the synthesis of certain medications. It also finds applications in the polymer industry, where it can be incorporated into polymers to enhance their properties. Additionally, it can be used in the production of certain sensors and as a precursor in the semiconductor industry for specific manufacturing processes.

When handling 3-Buten-1-ylbenzene (CAS: 768-56-9), it is important to use proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation. In case of a spill, use appropriate containment measures and do not allow the compound to enter drains. Always refer to the Safety Data Sheet (SDS) for specific handling and disposal instructions.
