Assignee:

UOP LLC - Des Plaines IL

International Classification:

C07C 720

US Classification:

585 5, 585832, 585 4, 208 2, 208 48 AA, 208348, 208349

Abstract:

Compounds that inhibit polymerization of vinyl aromatic compounds need to operate at temperatures of about 90Â C. to about 150Â C. A process for increasing the thermal stability of inhibitors such as N,Nâ-di-2-butyl-N,Nâ-dinitroso-1,4-diaminobenzene is disclosed. The process comprises adding to the inhibitor a stabilizer such as N,Nâ-di-2-butyl-1,4-diaminobenzene. The mixture of inhibitor and stabilizer is also used to inhibit polymerization of vinyl aromatic compounds.

Abstract:

A process is disclosed for inhibiting the polymerization of vinyl aromatic compounds, such as styrene, during its distillation. The process involves adding a mixture of at least two inhibitors to the vinyl aromatic compound. One such combination is N,Nâ-di-2-butyl-N,Nâ,4-dinitroso-1,4-diaminobenzene and dinitrocresol. A stabilizer such as N,Nâ-di-2-butyl-1,4-diaminobenzene can also be added.

Abstract:

In a process for the oligomerization of light olefins (e. g. propylene) to more valuable higher olefins (e. g. hexene), the use of a molecular sieve (e. g. SAPO-11) that has been acid washed has shown to provide superior selectivity to, and yield of, the desired product. These benefits are attributed to a reduction in non-selective acid sites as well as an increase in phosphorous content (in the case of SAPO molecular sieves) at the molecular sieve crystallite surface, a probable result of removing amorphous silicon aluminum phosphate acid, silicophosphorous acids, and/or phosphoric acids. Furthermore, this removal is likely accompanied by an increased accessibility of olefinic feed components to the so-called âselectiveâ acid sites within the sieve pores. Post-synthesis acid washing of the molecular sieve has not only demonstrated a narrower carbon number distribution of olefin oligomers, but also improved the linearity of the oligomerized olefinic product slate in general. Such increases in linearity generally correspond to overall higher product values, when downstream applications such as plasticizer intermediates are considered.

Abstract:

A process has been developed for oxygenating linear C to C alkanes to ketones or aldehydes. The process involves reacting the alkanes with oxygen in the presence of a catalyst comprising an imide promoter and a metal co-catalyst. An example of the imide is N-hydroxyphthalimide and an example of the co-catalyst is Co (acetylacetonate). The process is preferably carried out using an inert solvent, an example of which is acetic acid. Optionally, the oxygenated product can be hydrogenated to give the corresponding alcohol which can optionally in turn be dehydrated to provide the corresponding olefin.

International Classification:

C07C 202

US Classification:

585533, 585514, 585531

Abstract:

A process is disclosed for the oligomerization of light olefins to higher olefins. The process uses a catalyst that has an inert core and a thin layer of molecular sieve applied to the inert core. The molecular sieve is a crystalline silicoaluminate or metalloaluminophosphate and provides the acid sites for the oligomerization reactions. The thin layer provides for more selective control and limits the amount of oligomerization for liquid phase oligomerization processes.

Abstract:

A process for the production of C alkenes with high selectivities to 2,4,4-trimethylpentene by the oligomerization of isobutene and/or n-butene at lower temperatures is disclosed. Higher proportions of heavy paraffins mixed with the butene feed in the oligomerization zone improve the selectivity to 2,4,4-trimethylpentene along with better selectivity to octene and lower selectivity to dodecene. Additionally, we have found that n-butene codimerizes with isobutene selectively to 2,4,4-trimethylpentene.
