Hazard InformationBack Directory
【General Description】

Colorless liquid with a mild, choking alcohol odor. Less dense than water, soluble in water. Hence floats on water. Produces an irritating vapor.
【Reactivity Profile】

ISOAMYL ALCOHOL(123-51-3) attacks plastics [Handling Chemicals Safely, 1980. p. 236]. Mixtures with concentrated sulfuric acid and strong hydrogen peroxide may cause explosions. Mixing with hypochlorous acid in water or water/carbon tetrachloride solution can generate isoamyl hypochlorites, which may explode, particularly on exposure to sunlight or heat. Mixing with chlorine would also yield isoamyl hypochlorites [NFPA 491 M, 1991]. Base-catalysed reactions with isocyanates can occur with explosive violence [Wischmeyer,1969].
【Air & Water Reactions】

Highly flammable. Water soluble.
【Health Hazard】

Very high vapor concentrations irritate eyes and upper respiratory tract. Continued contact with skin may cause irritation.
