CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Cumene hydroperoxide is a 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 mmHg. 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. |
