| | 1,2,3,5-Tetramethylbenzene Usage And Synthesis |
| Chemical Properties | clear colourless to pale yellow liquid | | Uses | Organic synthesis. | | Synthesis Reference(s) | Journal of the American Chemical Society, 79, p. 6277, 1957 DOI: 10.1021/ja01580a044
Organic Syntheses, Coll. Vol. 2, p. 360, 1943 | | General Description | A pale yellow to white liquid with a camphor-like odor. Flash point 165°F. Less dense than water and only negligibly soluble in water. Slightly irritates the skin and eyes. Slightly toxic by ingestion but may irritate the mouth, throat and gastrointestinal tract. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 1,2,3,5-TETRAMETHYLBENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. | | Hazard | Liquid.
Soluble in alcohol and ether; insoluble in water.
Combustible. | | Health Hazard | CALL FOR MEDICAL AID. LIQUID: Irritating to skin, eyes, and respiratory tract. Remove contaminated clothing and shoes. Flush affected areas with plenty of water. IF IN EYES, hold eyelids open and flush with plenty of water. VAPORS: Irritating to skin, eyes and respiratory tract. Move to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen. IF IN EYES, hold eyelids open and flush with plenty of water. Harmful if inhaled or swallowed. Vapor or mist is irritating to the eyes, mucous membranes, and upper respiratory tract. Prolonged contact can cause dermititis, and prolonged exposure can cause nausea, dizziness and headache. | | Fire Hazard | Combustible. | | Purification Methods | Reflux isodurene over sodium and distil it under reduced pressure.
