1-Methoxy-2-propanol Usage And Synthesis

Chemical Properties colourless liquid
General Description A colorless liquid. Flash point near 89°F. Less dense than water. Contact irritates skin, eyes and mucous membranes. Prolonged exposure to vapors may cause coughing, shortness of breath, dizziness and intoxication. Vapors heavier than air. Used as a solvent and as an antifreeze agent.
Air & Water Reactions Highly flammable. Soluble in water. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164].
Reactivity Profile 1-Methoxy-2-propanol is a methoxy alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Health Hazard VAPOR: Irritating to eyes, nose, and throat. LIQUID: Irritating to skin and eyes.
Fire Hazard FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area.
