1,2,3-트리메틸벤젠 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid

물리적 성질

Clear, colorless, flammable liquid with an aromatic odor similar to propylbenzene, ethylbenzenes, or xylenes.

용도

Raw material for chemical synthesis.

정의

ChEBI: A trimethylbenzene carrying methyl groups at positions 1, 2 and 3. It has been found in Centaurium erythraea.

위험도

Combustible. Central nervous system impairment, asthma, and hematologic effects.

Safety Profile

Mildly toxic by ingestion, Flammable liquid when exposed to heat, sparks, or flame. To fight fire, use water spray, mist, dry chemical, CO2, foam. When heated to decomposition it emits acrid smoke and irritating fumes.

잠재적 노출

(1,2,3-and 1,2,4-isomers): These materials are used as solvents and in dye and perfume manufacture. The 1,2,3-isomer is used as raw material in chemical synthesis and as an UV stabilizer. The 1,2,4-isomer is used as the raw material for trimellitic anhydride manufacture. These compounds are found in diesel engine exhaust fumes.

환경귀착

Photolytic. Glyoxal, methylglyoxal, and biacetyl were produced from the photooxidation of 1,2,3-trimethylbenzene by OH radicals in air at 25 °C (Tuazon et al., 1986a). The rate constant for the reaction of 1,2,3-trimethylbenzene and OH radicals at room temperature was 1.53 x 10-11 cm3/molecule?sec (Hansen et al., 1975). A rate constant of 1.49 x 10-8 L/molecule?sec was reported for the reaction of 1,2,3-trimethylbenzene with OH radicals in the gas phase (Darnall et al., 1976). Similarly, a room temperature rate constant of 3.16 x 10-11 cm3/molecule?sec was reported for the vapor-phase reaction of 1,2,3-trimethylbenzene with OH radicals (Atkinson, 1985). At 25 °C, a rate constant of 2.69 x 10-11 cm3/molecule?sec was reported for the same reaction (Ohta and Ohyama, 1985). 2,3-Butanedione was the only products identified from the OH radical-initiated reaction of 1,2,4-trimethylbenzene in the presence of nitrogen dioxide. The amount of 2,3- butanedione formed decreased with increased concentration of nitrogen dioxide (Bethel et al., 2000).
Chemical/Physical. 1,2,3-Trimethylbenzene will not hydrolyze because it does not contain a hydrolyzable group (Kollig, 1993).

운송 방법

UN3295 Hydrocarbons, liquid, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid. UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required. 1,3,5-Trimethylbenzene; UN2325, Hazard Class: 3; Labels: 3-Flammable liquid. 1,2,4-Trimethylbenzene:

비 호환성

Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

폐기물 처리

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
