The Houston alkylation
unit was successfully commissioned in the second quarter of 2019.
The latter include the use of an aqueous NaOH solution at 50% in toluene, which means that the organic solvent does not need to be in an anhydrous condition, as would be necessary for a conventional alkylation
Due to high boiling, high viscous, high sulfur content and complex nature of a crude oil, the separation is difficult to proceed so make it easy the sulfur compounds goes through first alkylation
and oxidation method
As this alkylation
method is not widely applied for the preparation of aza-amino acid precursors it required optimization.
The UNB team included Jeremy Hughes, Bruce Scott, Erin Flanagan and Cody Brown, whose project, "The Use of Solid Catalyst Technology in the Alkylation
of Refinery Grade Propylene," was sponsored by Irving Oil Ltd.
Boston-based Badger Licensing LLC is a joint venture between the Badger Technology Holdings, an affiliate of Technip, and Alkylation
Licensing, an affiliate of ExxonMobil Chemical Company.
In the same report, another general strategy from the synthesis of ispinesib followed was N- alkylation
of amino acid prior to the formation of quinazolinone nucleus (Scheme 3).
Such competitive adsorption effects can be expected in Friedel-Crafts-type alkylation
reactions with zeolites, because molecules of completely different physiochemical nature are involved (i.e., aromatic substrate and alkylating agents such as alcohols, esters, anhydrides, etc.).
'Now we produce two million liters of 100 LL gasoline per day in alkylation
unit of Aban oil refinery, which is a strategic product and is used as fuel by planes and helicopters' Qasemi noted.
Pilot Chemical's proprietary technologies include: alkylation
, sulfonation, sulfation and a number of other specialty operations.
The major project involves the installation of a Vacumm Distillation Unit, Light Olefine Alkylation
Unit, Light Gasoline Isomerization Unit, Gasoline Mixing Unit and Utility System.
value for propylene in motor gasoline remains over $0.75/lb.
