||The Octol process can produce octenes (C8's) and/or C12's as intermediates to plasticizers and surfactants. Made by catalytic dimerization of n-butenes, the olefin products exhibit a low degree of branching and are obtained at high yields.
||To make octenes by dimerization of butylenes or a mixture of olefins by codimerization of propylene and butylenes.
||The process is suitable for the production of n-butyraldehyde from propylene and syngas (carbon monoxide/hydrogen).
||Processes for the production of polyethylene terephthalate (PET) starting from ethylene glycol (EG) and terephthalic acid (TPA) or dimethylterephthalate (DMT).
||A novel process for the production of propylene oxide from propylene and hydrogen peroxide via perpropionic acid.
||A continuous process for the manufacture of a protein feeding stuff based on the fermentation of methanol by a selected microorganism.
||A process for the recovery of the highest purity paraxylene commercially available by crystallization from mixed xylenes.
||A process for separating p-xylene from mixtures with other xylene isomers, ethylbenzene and non-aromatic hydrocarbons. The p-xylene is recovers at a purity in excess of 99.5%. The process typically recovers 95% of the p-xylene charged in a single pass, but recoveries in excess of 96% are possible.<br>
The process can be operated to extract p-xylene in a once through operation from either a C8-aromatic mixture derived from extraction or from a C8-cut of reformate or pyrolysis gasoline from steam cracking. Alternatively, it can be operated in conjunction with xylene isomerization, such as UOP's Isomar process, to yield any required proportion of the C8-aromatic products as p-xylene.
||Xylenes and benzene
||A process to convert toluene or toluene and C9 aromatics to xylenes and benzene by disproportionation and transalkylation.
