Chemical Properties colourless liquid

General Description Colorless to light yellow liquid with a sharp, irritating odor. Flash point 175°F. Boils at 153°C and at 100°C at the reduced pressure of 8 mm Hg. Slightly soluble in water and denser than water. Hence sinks in water. Readily soluble in alcohol, acetone, esters, hydrocarbons, chlorinated hydrocarbons. Toxic by inhalation and skin absorption. Used in production of acetone and phenol, as a polymerization catalyst, in redox systems.

Air & Water Reactions Slightly soluble in water and oxidized in air at approximately 130°C.

Reactivity Profile Cumyl hydroperoxide is a strong oxidizing agent. May react explosively upon contact with reducing reagents Violent reaction occurs upon contact with copper, copper alloys, lead alloys, and mineral acids. Contact with charcoal powder gives a strong exothermic reaction. Decomposes explosively with sodium iodide [Chem. Eng. News, 1990, 68(6), 2]. Can be exploded by shock or heat [Sax, 2 ed., 1965, p. 643]. May ignite organic materials.

Health Hazard Inhalation of vapor causes headache and burning throat. Liquid causes severe irritation of eyes; on skin, causes burning, throbbing sensation, irritation, and blisters. Ingestion causes irritation of mouth and stomach.
