Overview | α-methylstyrene (a-MS or AMS for short), also known as α-methylstyrene or phenylisopropene, is cumene production of phenol and acetone by-products, generally per ton of phenol production of 0.045T alpha-Ms. Α-methylstyrene is a colorless liquid with a pungent odor. The molecule contains a benzene ring and an alkenyl substituent on the benzene ring, and is susceptible to polymerization when heated. |
uses | α-methylstyrene is a by-product of cumene production of phenol acetone, and its main uses are as follows: 1. The intermediate of organic synthesis α-MS is the basic raw material of organic synthesis, which can be used to synthesize cumene, dicumyl peroxide, P-cumyl phenol and so on. The copolymerization monomer α-MS can be used as a resin modifier and copolymerized with acrylonitrile, methyl methacrylate, maleic anhydride and the like to produce copolymerization resins with different characteristics. |
