3 -Ethyl-1, 2, 4-trimethylbenzene

The Tatoray process, which was developed by Toray Industries, Inc., and is available for Hcense through UOP, can be appHed to the production of xylenes and benzene from feedstock that consists typically of toluene [108-88-3] either alone or blended with aromatics (particularly trimethylbenzenes and ethyl-toluenes). The main reactions are transalkylation (or disproportionation) of toluene to xylene and benzene or of toluene and trimethylbenzenes to xylenes in the vapor phase over a highly selective fixed-bed catalyst in a hydrogen atmosphere at 350—500°C and 1—5 MPa (10—50 atm). Ethyl groups are... [Pg.52]

XAD-2 macroreticular resin columns. This situation implied that the XAD-2 column was not effective in retaining completely all the solutes present in the water samples. [NOTE The XAD-2 resin column contained about 25% more packing, and the rate of percolation was about the same as that normally used for processing 200 L of tap water (21).] In addition, a variety of volatiles that appeared immediately following the solvent peak were also present. Subsequent analysis of these concentrates by GC-MS indicated the presence of 6-chloro-2,4-diamino-1,3,5-triazine (tentative), 2,5-diphenylisoxazole (tentative), tributoxyethyl phosphate (confirmed), bis(2-ethylhexyl) phthalate (confirmed), and dimethylbenzoic acid (confirmed) from site 1. The concentrate from site 2, however, showed the presence of 2,4,5-trichlorophenol (confirmed), BHC (confirmed), 2,5-diphenylisoxazole (tentative), bis(2-ethyl-hexyl) phthalate (confirmed), trimethylbenzene (confirmed), ethylbenz-aldehyde (confirmed), ethylacetophenone (confirmed), hexanoic acid (confirmed), and 4-cyano-3,7,ll-tridecatriene (tentative). [Pg.177]

Disposal bins have been studied for the VOCs associated with them by Stathero-poulos, Agapiou and Pallis (2005). The most prominent classes of compounds emitted are generally aliphatic and aromatic hydrocarbons, esters, terpenes and alcohols. The highest median concentrations for a single compound was 649.9 tg/ m 1 for decane while median concentrations of several other compounds such as limonene, undecane, nonane, ethanol, acetic acid ethyl ester and 1, 2,4-trimethylbenzene are in the range 159.1-353.1 pg/nf3. Therefore, waste bins are not only sources of odorants but sources of VOC as well. [Pg.367]

The primary tropospheric oxidants are OH, O3, and NO3, with "OH and O3 reactions with hydrocarbons dominating primarily during daytime hours, and NO3 reactions dominating at night. Rate constants for the reactions of many different aromatic compounds with each of the aforementioned oxidants have been determined through laboratory experiments [16]. The rate constant data as well as atmospheric lifetimes for the reactions of toluene, m-xylene, p-xylene, m-ethyl-toluene, and 1,2,4-trimethylbenzene appear in Table 14.1. Only these particular aromatic compoimds will be discussed in this review paper, since much of the computational chemistry efforts have focused on these compounds. When considering typical atmospheric concentrations of the major atmospheric oxidants, OH, O3, and NO3 of 1.5 x 10, 7 x 10, and 4.8 x 10, molecules cm , respectively [17], combined with the rate constants, it is clear that the major atmospheric loss process for these selected aromatic compounds is reaction with the hydroxyl... [Pg.298]

The pore size of mordenites depends both on the source of mordenite and on the extent and nature of cation exchange. Various shape-selective catalyses have been observed with mordenites of different types. Transition-state selectivity occurs as well as reactant and product selectivity, especially in the alkylation and transalkylation of alkyl benzenes. High selectivity for 1,2,4-trimethylbenzene has been found in the disproportation of toluene over partially-exchanged H-mordenites. Karge found the selective formation of monoalkyl benzenes in the ethylation of benzene over various cation-containing mordenites and attributed the results to transition-state selectivity. [Pg.217]

The generation of ethoxycarbonylcarbene by thermal cleavage of ethyl diazoacetate is usually effected at 140-150 C. At 100°C this diazo ester has a half-life time of 109 hours in the inert solvent 1,3,5-trimethylbenzene. A second substituent at the diazo carbon can markedly influence the thermal stability of the diazo ester. For example, the phenyl group, as well as acyl and sulfonyl substituents reduce the thermal stability, whereas the diethoxyphosphoryl and trialkylsilyl groups enhance it. [Pg.426]
