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

Chemical Properties

clear colourless liquid

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].

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.

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
