2-Phenyl-1-propene Chemical Properties,Uses,Production
Chemical Properties
clear colourless liquid
Physical properties
Colorless liquid with a sharp aromatic odor. Odor threshold concentration is 290 ppb (quoted, Amoore and Hautala, 1983).
Uses
Polymerization monomer, especially forpolyesters.
Production Methods
α-Methylstyrene (AMS) is produced as a by-product in the production of phenol and acetone from cumene.
General Description
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.
Air & Water Reactions
Flammable. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water.
Reactivity Profile
2-Phenyl-1-propene is easily peroxidizable; the peroxide may initiate exothermic polymerization of the bulk material. Reacts violently with strong oxidizing agents [Handling Chemicals Safely, 1980 p. 866; Bretherick, 1979 p. 160].
Hazard
Moderate fire risk. Explosive limits in air1.9–6.1%. Avoid inhalation and skin contact. Upperrespiratory tract irritant, kidney and female repro-ductive damage. Possible carcinogen.
Health Hazard
Inhalation causes irritation of respiratory tract, headache, dizziness, light-headedness, and breathlessness. Ingestion causes irritation of mouth and stomach. Contact with liquid irritates eyes. Prolonged skin contact can cause severe rashes, swelling, and blistering.
Safety Profile
Mildly toxic by inhalation. Human systemic effects by inhalation: irritant effects. A skin and eye irritant. Flammable when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes.
Potential Exposure
Methylstyrene is used as additive, plasticizer, and copolymer; used in the production of modified polyester and alkyd resin formulations.
Environmental Fate
Chemical/Physical. Polymerizes in the presence of heat or catalysts (Hawley, 1981).
Shipping
UN2303 Isopropenylbenzene, Hazard Class: 3; Labels: 3-Flammable liquid
Purification Methods
Wash the monomer three times with aqueous 10% NaOH (to remove inhibitors such as quinol), then six times with distilled water, dry with CaCl2 and distil it unde
Incompatibilities
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, peroxides, halogens, catalysts for vinyl or ionic polymers; aluminum, iron chloride; copper. Methylstyrene may form unstable peroxides; may polymerize. Usually contains an inhibitor, such as tert-butyl catechol.
Waste Disposal
ncineration, often by admixture with a more flammable solvent
