Note. Hydrocarbons such as ethyl-benzene can also be prepared by the Clemmensen reduction of the corresponding ketone. This is exemplified by the reduction of methylacetophenone (p. 290)]. 

Ethyl-benzene is a colourless liquid of b.p. 134°, and 0-876 it has only a faint odour. 

Figure 6.8 Effect of chain transfer to solvent according to Eq. (6.89) for polystyrene at 100°C. Solvents used were ethyl benzene ( ), isopropylbenzene (o), toluene (- ), and benzene (°). [Data from R. A. Gregg and F. R. Mayo, Discuss. Faraday Soc. 2 328 (1947).]...

The performance of many metal-ion catalysts can be enhanced by doping with cesium compounds. This is a result both of the low ionization potential of cesium and its abiUty to stabilize high oxidation states of transition-metal oxo anions (50). Catalyst doping is one of the principal commercial uses of cesium. Cesium is a more powerflil oxidant than potassium, which it can replace. The amount of replacement is often a matter of economic benefit. Cesium-doped catalysts are used for the production of styrene monomer from ethyl benzene at metal oxide contacts or from toluene and methanol as Cs-exchanged zeofltes ethylene oxide ammonoxidation, acrolein (methacrolein) acryflc acid (methacrylic acid) methyl methacrylate monomer methanol phthahc anhydride anthraquinone various olefins chlorinations in low pressure ammonia synthesis and in the conversion of SO2 to SO in sulfuric acid production. 

Efficiency and pressure drop data for Siilzer BX metal gauze structured packing and for three test mixtures are shown in Fig. 14-7.5. For the ethyl benzene/styrene test mixture, the effect of operating pressure is shown. The high viscosity mixture, propylene glycoL/ethylene...

Thermodynamics. Along with stated yields goes heat requirements for the reactor. The thermodynamics for this operation should be checked, as the author once did for a proposed ethyl-benzene dehydrogenation process. Ethylbenzene and steam w-ere fed to the reactor, and unreacted ethyl-benzene and steam exited the reactor together with the sought product, styrene, and eight side products.

Corrective Action Application Case 1 - Groundwater at the MEMOREX Computer Tape Plant (Santa Clara, California) was contaminated by a leaking underground solvent storage tank (Skladany et al., 1987). Chemical analysis of the groundwater identified the presence of methyl ethyl ketone (MEK) up to 500 ppm xylenes together with ethyl benzene up to 40 ppm cyclohexanone up to 30 ppm cyclohexanol up to 10 ppm acetone up to 10 ppm and toluene, tetrahydrofuran, 2-butanol, and methyl propyl ketone each less than 1 ppm.
