Overview
Beta-Methylstyrene, also known as 2-Phenylpropene, is an organic compound with the molecular formula C9H10. It is a derivative of styrene and is characterized by a reactive double bond and an aromatic ring. This compound is primarily used in industrial applications, including the production of polymers and as an intermediate in chemical synthesis. Beta-Methylstyrene is typically found as a colorless to pale yellow liquid with a distinctive aromatic odor. It is insoluble in water but dissolves readily in organic solvents such as ethanol and ether. Due to its chemical structure, it is highly reactive and can participate in various polymerization reactions.
Physical and Chemical Properties
Beta-Methylstyrene has a molecular weight of 118.18 g/mol and a density of 0.91 g/cm³ at 20°C. Its melting point is -23°C, and it boils at 165-169°C under standard conditions. The compound is insoluble in water but exhibits good solubility in organic solvents, making it useful in various chemical processes. The key chemical property of Beta-Methylstyrene is its reactive double bond, which allows it to participate in polymerization reactions. This reactivity is exploited in the production of copolymers and other specialty polymers. The compound also has a characteristic aromatic odor, which makes it suitable for use in fragrance synthesis.
Main Applications
Beta-Methylstyrene is widely used in the polymer industry, where it serves as a monomer for producing copolymers and other specialized polymers. These polymers are often used in adhesives, coatings, and plastic products due to their durability and chemical resistance. In addition to its role in polymer production, Beta-Methylstyrene is used as an intermediate in the synthesis of fragrances and flavorings. Its aromatic properties contribute to the scent profiles of various consumer products. The compound is also employed in research and development for creating new chemical entities with potential industrial or pharmaceutical applications.
Safety and Storage
Beta-Methylstyrene is a flammable liquid and vapor, requiring careful handling to prevent fire hazards. It should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. Proper grounding of containers is necessary to avoid static discharge. The compound can cause skin and eye irritation upon contact, so personal protective equipment (PPE) such as gloves and goggles should be worn when handling it. Adequate ventilation is essential to minimize inhalation exposure. In case of spills, absorb the material with an inert substance and dispose of it according to local regulations.
B2B Procurement Guide
When procuring Beta-Methylstyrene, it is crucial to verify the purity specifications provided by the supplier, as impurities can affect its performance in industrial applications. Reputable suppliers should offer certificates of analysis (CoA) to confirm the product's quality. Considerations should also include the supplier's reliability, delivery timelines, and compliance with safety and environmental regulations. Bulk purchases may offer cost advantages, but storage capacity and shelf-life should be evaluated to prevent degradation. Always ensure that the material is transported and stored under recommended conditions to maintain its integrity.
