| | 4-Chloro-2-methylphenol Usage And Synthesis |
| Chemical Properties | Off-white to slightly brownish crystalline solid | | Uses | 4-Chloro-2-methylphenol is a transformation/degredation product of herbicides found in the environment through landfills and runoff. | | Definition | ChEBI: A member of the class of phenols that is o-cresol in which the hydrogen para to the hydroxy group is replaced by a chlorine. | | Synthesis Reference(s) | Tetrahedron Letters, 30, p. 5215, 1989 DOI: 10.1016/S0040-4039(01)93745-1 | | General Description | Dark red flakes with waxy texture. Insoluble in water. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 4-Chloro-2-methylphenol can react vigorously with concentrated sodium hydroxide solutions. Also reacts with other bases, acid chlorides, acid anhydrides, and oxidizing agents. Corrodes steel, brass, copper and copper alloys [NTP, 1992)]. A large quantity left in contact with concentrated sodium hydroxide solution for 3 days reacted violently, attaining red heat and evolving fumes that ignited explosively. The heat of reaction dissipated poorly because of the high viscosity of the mixture [Quart. Safety Summ., 1957, 28, 39]. | | Fire Hazard | 4-Chloro-2-methylphenol is probably combustible. | | Flammability and Explosibility | Nonflammable | | Purification Methods | Purify the phenol by crystallisation from pet ether (m 51o) and by zone melting.
