1 1
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
Instability   1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

2-Phenyl-1-propene Chemical Properties,Uses,Production

Chemical Properties

clear colourless liquid

Chemical Properties

Methylstyrene is a colorless liquid with a characteristic odor.

Uses

Polymerization monomer, especially forpolyesters.

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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit

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
