2-Phenyl-1-propene, also known as Alpha Methyl Styrene(abbreviated as a-MS or AMS) or phenylisopropene, is a by-product of the production of phenol and acetone by the cumene method, generally a by-product of phenol per ton 0.045t α-MS.Alpha Methyl Styren is a colorless liquid with a pungent odor. The molecule contains a benzene ring and an alkenyl substituent on the benzene ring.Alpha Methyl Styren is prone to polymerization when heated. Alpha Methyl Styren can be used in the production of coatings, plasticizers, and as a solvent in organic.


Physicochemical propertyAlpha Methyl Styrene is a colorless liquid. Insoluble in water and less dense than water. Flash point 115°F. May be mildly toxic by ingestion, inhalation and skin absorption. Vapors may be narcotic by inhalation. Used as a solvent and to make other chemicals.

Applications Of AMS:

Alpha Methyl Styrene can be used as a monomer for polymers such as toluene-butadiene rubber and high temperature plastics. It can also be used to prepare coatings, hot melt adhesives, plasticizers and synthetic musk. In Japan, 90% of α-methylstyrene is used as a modifier for ABS resin, and the rest is used as a solvent and raw material for organic synthesis.

1.Intermediate for ABS plastics, Styrene - Butadiene rubber, Polystyrene, Styrene - Acrylonitrile Resins, Perfumery, Polyalphamethyl Styrene, Polyester resins.
2.Polymerization monomer, especially forpolyesters.
3.α-Methylstyrene is not a styrenic monomer in the strict sense. The methyl substitution on the side chain, rather than the aromatic ring, moderates its reactivity in polymerization. It is used as a specialty monomer in ABS resins, coatings, polyester resins, and hot-melt adhesives. As a copolymer in ABS and polystyrene, it increases the heat-distortion resistance of the product. In coatings and resins, it moderates reaction rates and improves clarity.

Production method: In the production of phenol and acetone by isopropylbenzene process, the by-product of α-methylstyrene, annual output of phenol and acetone 10000 tons of the device, about 500t by-product α-methylstyrene. The product can also be obtained by dehydrogenation of isopropylbenzene in the presence of catalyst. However, in industry,the by-product α-methylstyrene is often hydrogenated to isopropylbenzene.

Storage: Generally, commodities are added with polymer. The temperature stored in a cool and ventilated warehouse does not exceed 30 ° C. Stay away from fire and heat. Packaging is required to be sealed and cannot be contacted with air. should be kept away from oxidizer, do not store together. It should not be stored in large quantities or last. Explosion -proof lighting and ventilation facilities. It is forbidden to use machinery and tools that are prone to sparks. The storage area should have leakage emergency treatment equipment and suitable containment materials.

Product packaging: 180KG/drum
