Introduction
α-Methylstyrene is an organic compound. It is a colorless liquid with a distinctive odor and is poorly soluble in water, but can be soluble in organic solvents such as ethanol and carbon disulfide.α-methylstyrene is an important chemical raw material, which is widely used in synthetic fragrances, resins and synthetic rubber. It can be used as an intermediate in the synthesis of α-vinylbenzene, or as a monomer in the preparation of styrene-propylene polymers.There are several preparation methods for α-methyl styrene, and the commonly used is to heat the methyl styrene sulfonate to an appropriate temperature with a copper catalyst by thermal decomposition method, and α-methyl styrene can be generated.α-Methylstyrene is toxic and irritating to the eyes and skin. When using or storing, wear appropriate personal protective equipment and avoid contact with skin and eyes. It should be properly stored away from fire sources and high temperature environments to prevent fire or explosion.
