Trimethylbenzene (TMB), as a constituent of gasoline, is often expected to be used as a conservative tracer in anaerobic BTEX-contaminated groundwater site to correct for attenuation due to dispersion, dilution and sorption along a flow path. To evaluate the suitability of using TMB as a ...
Trimethylbenzene (TMB; CAS 25551-13-7) is a commercially available mixture of three individual isomers: 1,2,4-, 1,2,3-, and 1,3,5-TMB. TMB isomers are produced during petroleum refining. TMB exposure in humans occurs primarily through inhalation, although ingestion of TMB isomers through ...
Trimethylbenzene refers to a mixture of three isomers: 1,2,3-TMB, 1,2,4-TMB, and 1,3,5-TMB. It is a chemical compound with the molecular formula C9H12. AI generated definition based on: Encyclopedia of Toxicology (Third Edition), 2014 ...
2,3,5-trimethyl hydroquinone(TMHQ) was prepared from 1,2,4 trimethyl benzene(TMB) in new oxidizer system(HAc H 2O 2 H 2SO 4). 提出了一种新的由偏三甲苯制取三甲氢醌的氧化剂体系 (冰醋酸 -过氧化氢 -浓硫酸 )。 2. Calculation for separation and purification process of crude 1,3,5 ...
The acute initial threshold screening level (ITSL) for all trimethylbenzene (TMB) isomers combined is 1200 μg/m3 with 8-hr averaging time. Waste Disposal Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All ...
Using nonrigid group theory, the full nonrigid (f-NRG) group of 1,3,5-trimethylbenzene (TMB) is shown to be isomorphic to the group S3[C3] = C3 S3 of order 162, where denotes the wreath product of groups, and C3 is the cyclic group of order three and S3 is the symmetric group ...
Analytical results from LC/TOF-MS showed the particulate products formed by the reaction of 1,3,5-TMB to be richer in ketocarboxylic acids than for benzene. These results indicate that SOA aging proceeds mainly by formation of carboxylic acids and that the rate of SOA aging in laboratory ...

Inhalation of high concentrations may cause CNS effects; [ICSC] TLV Basis: CNS impairment and hematologic effects; "This value [TLV] should protect against hematologic effects, such as reversible increased reticulocyte counts observed in female Wistar rats exposed to 1,2,3-TMB, for which the LOAE...
However, experimentally calculated tissue-specific partition coefficients were similar for all three isomers across a number of organ systems (fat, brain, liver, muscle, and kidney), strongly suggesting that 1,2,4-TMB, 1,2,3-TMB, and 1,3,5-TMB can be expected to partition into similar ...
