Benzene, tetraethyl

The importance of methods of analysis for new insecticides is evidenced by the fact that during the past two years industry and government have cooperated in developing methods for two of them—tetraethyl pyrophosphate and benzene hexachloride (1,2,3,4,5,6-hexachlorocyclohexane) (37, 45).

Phenoxanthin, 68 X = S Y = O, is prepared by the electrochemical oxidation of diphenyl ether in dichloromethane and trichloroacetic acid containing tetraethyl-ammonium perchlorate at a composite anode of carbon and sulphur. The anode generates sulphur cations, which carry out electrophilic substitution on the benzene ring [237], Phenoxathiin radical-cation, formed at the potential of the fust oxidation wave, has been characertised by esr spectroscopy [238],... 

Elemental composition Pb 64.06%, C 29.70%, H 6.23%. Tetraethyl lead is dissolved in benzene or toluene, diluted appropriately, and analyzed by GC/MS. The ethyl group may be determined by NMR spectroscopy.

Synonym tetraethylplumbane, lead tetraethyl Formula Pb(C2H5)4 MW 323.47 CAS [78-00-2] used in motor gasoline as an additive to prevent knocking such an application, however, is currently curtailed because of environmental pollution boils at 200°C vapor pressure 0.2 torr at 20°C density 1.653 g/mL at 20°C insoluble in water slightly soluble in alcohols dissolves in benzene, toluene, hexane, petroleum ether, and gasoline highly toxic (Patnaik, 1992). 

Solubile in water at 20°C, 0.004% miscible with alcohol, ether, petroleum ether, cyclohexane, benzene, and similar hydrocarbons. More stable in alkaline formulation than when at neutral or acid pH. On storage with traces of water, highly toxic tetraethyl thiopyrophosphate is produced.1... 

Toluene is generally produced along with benzene, xylenes, and C9 aromatics by the catalytic reforming of C6-C9 naphthas. The resulting crude reformate is extracted, most frequently with sulfolane (Fig. 1) or tetraethyl-ene glycol and a cosolvent, to yield a mixture of benzene, toluene, xylenes, and C9-aromatics, which are then separated by fractionation.
