| Hazard Information | Back Directory | [General Description]
Colorless crystals with a camphor-like odor. | [Reactivity Profile]
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 1,2,4,5-TETRAMETHYLBENZENE(95-93-2), 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. | [Air & Water Reactions]
Insoluble in water. | [Chemical Properties]
white to brown semi-transparent crystals | [Physical properties]
Colorless crystals or scales with a camphor-like odor | [Uses]
1,2,4,5-Tetramethylbenzene is used in method for reducing odor in room in remodeling work by removing causative substances. | [Uses]
Plasticizers; polymers; fibers; organic synthesis. | [Definition]
ChEBI: Durene is a tetramethylbenzene carrying methyl groups at positions 1, 2, 4 and 5. | [Synthesis]
Even tetramethylbenzene is one of the components of coal tar, originally prepared from metatrimethylbenzene in 1870. It is obtained by the methylation reaction of other toluene, such as p-xylene or meta-trimethylbenzene.
C6H4(CH3)2 + 2CH3Cl &rar | [Purification Methods]
Chromatograph durene on alumina, and recrystallise it from aqueous EtOH or *benzene. Zone-refining removes duroaldehydes. Dry it under vacuum. [Yamauchi et al. J Phys Chem 89 4804 1985.] It has also been sublimed in vacuo [Johnston et al. J Am Chem Soc 109 1291 1987]. [Beilstein 5 H 431, 5 I 207, 5 II 329, 5 III 979, 5 IV 1076.] | [Toxics Screening Level]
The initial threshold screening level (ITSL) for 1,2,4,5-tetramethyl benzene is 20 μg/m3 (annual averaging time). |
