Benzene Co

The ability of the rhenium-benzene co-condensate to activate linear- and cyclic- alkanes is quite general. We have co-condensed rhenium atoms with alkane benzene mixtures using the alkanes ethane, propane, butane, 2-methylpropane, neopentane,... 

The production of ethylene by gas crackers, mostly from C2, C3, and some C4 feeds, amounts to about 40% of the world ethylene capacity. This results in a small coproduction of benzene compared to benzene co-produced in naphtha and gas oil crackers, which account for 60% of the world s ethylene production capacity. A typical overall benzene yield from ethane cracking is on the order of only 0.6% of the ethane feed, and the yield of benzene from propane cracking is on the order of 3% of the propane feed. In contrast, the...

In 2003 the Rectisol process is offered for licensing by both companies for the removal of C02, H2S, HCN, 0 6 (benzene), COS and gum-forming hydrocarbons from syngas and fuel gas. In 2003, over 70 units were in operation or under construction1. 

TGA of the toluene co-crystal 2 showed a mass loss of 14.8% at 183 °C. The host crystals with the empty channels were soaked in toluene for 36 hours and then subjected to TGA. These crystals showed a mass loss of 9.2% at 166 °C, a behaviour similar to that of the benzene co-crystal, 1. TGA of the /7-xylene cocrystal, 5, showed a mass loss (12.2%) due to the removal of the aromatic guest around 167 °C. After reintroduction of /7-xylene in the channels, the mass loss occurred around 139 °C, but the magnitude of mass loss was smaller... 

Application To convert C9+ heavy aromatics, alone or in conjunction with toluene or benzene co-feed, primarily to mixed xylenes using ExxonMobil Chemical s TransPlus process. 

Description Dry toluene feed and hydrogen-rich recycle gas are pumped through feed/effluent exchangers and charge heater and into the PxMax reactor (1). Selective toluene disproportionation (STDP) occurs in the vapor phase to produce the paraxylene-rich xylene and benzene co-product. Byproduct yields are small. Reactor efflu-...

Hexamethyl Dewar Benzene co-ordinates as a pz-allylic ligand with palladium (II). The structure of the complex [Pd(acac)dehydro-HMDB] is shown in D.XX mT With platinum, however, pz -o-bonding is preferred as in the dimeric planar [PtCl-dehydro HMDB]2, D.XXI 122>. 

In general these compounds have to be prepared by indirect methods from other compounds, although it is sometimes possible to combine metal and ligand directly. Ni is most reactive, combining directly with CO, CH3PC12, and l,2-bis(diethylphosphino)benzene. Co and Pd also combine with the last of these, and the metals Fe, Co, Mo, W, Rh and Ru also combine with CO, but with the exceptions of Ni and Fe the reactions are too sluggish to be of practical value.
