"In addition, we successfully commissioned the new alkylation
unit at the Houston refinery to improve our margin capture going forward."
The unit, which will replace an existing HF alkylation
unit, will rely on the ISOALKYTM Technology developed by Chevron USA Inc.
The company has introduced a range of kits based on the new genome-wide, non-invasive, quantitative, fast, and reliable SLAMseq (thiol (SH)-Linked Alkylation
for the Metabolic Sequencing of RNA) method, developed by Stefan Ameres' research group at IMBA.
The complex was to have an aromatics plant with a capacity of over 115,000 t/y of benzene, 20,000 t/y of toluene, plus a 100,000 t/y alkylation
unit and a 30,000 t/y catalytic condensation unit.
We did not detect the transfer of an ethyl group from the TEBAC salt nor any long-chain alkylation
in the case of tetradecyltrimethylammonium bromide.
Desulfurization on the basis of alkylation
is very useful method for the removal of specific sulfur compounds called it thiophenes.In commercial scale this method is useful for light hydrocarbons.
They cover asymmetric C-H bond insertion reactions, symmetric cross-dehydrogenative coupling reactions, asymmetric oxidative biaryl coupling reactions, asymmetric [1,5]-hydride transfer reactions, asymmetric functionalization of C-H bonds via a transient carbon-metal species, asymmetric Friedel-Crafts alkylation
reactions, N-heterocyclic carbene-catalyzed asymmetric functionalization of aldehyde C-H bonds, asymmetric hydroacylation reactions, and asymmetric hydrovinylation reactions.
The company specializes in a wide range of organic reaction technologies such as Amination, condensation, hydrogenation; Amidation, dehydrogenation & Mannich Reaction; Alkylation
, diazotization & nitration; Bromination, esterifiction & oxidation; Catalytic hydrogenation, etherification & reduction; Chlorination & hydrogenation.
Dr Matthew Clingerman, EMEA regional engineering manager for DuPont Clean Technologies, provided delegates with up-to-date information on Stratco alkylation
and IsoTherming hydroprocessing technologies and their role in producing clean fuels.
The most frequently used synthetic route for the preparation of N-protected alkyl- and arylhydrazines is reductive hydrazine alkylation
(Scheme 1, left side).
It is also used for petroleum alkylation
, steel pickling, glass etching and production of nitrogen trifluoride.
They discovered that combining the hydrogen-poor olefinic light gases that were a side product of catalytic cracking with isobutane in an alkylation
reaction resulted in very high-octane (close to 100) gasoline blendstocks.
