• alkylate
  • The unique feed stream (100-percent isobutylene) available from the Hengli Petrochemical facility marks the beginning of a new era for alkylation in the gasoline market as the butane-to-alkylate movement grows around the world. (prweb.com)
  • The grassroots refinery complex, with the addition of STRATCO® alkylation technology, will allow Hengli to produce a high quality alkylate product (used as a blending component in the gasoline pool) from a 100% isobutylene feed stream. (prweb.com)
  • b) passing said hydroisomerate stream (26) to an alkylation unit (24) and alkylating said hydroisomerate stream (26) by a branched chain paraffin hydrocarbon to produce an alkylate stream (32). (epo.org)
  • Refineries use the alkylation process to convert low value mixed butylene, propylene and/or amylene feed streams into a high value alkylate product. (hydrocarbonprocessing.com)
  • For upgrading of petroleum, alkylation produces synthetic C7-C8[further explanation needed] alkylate, which is a premium blending stock for gasoline. (wikipedia.org)
  • High quality motor fuel alkylate is produced in a combination process comprising hydrofluorination of an olefin-containing hydrocarbon stream with HF to produce alkyl fluorides, separation of the produced alkyl fluorides into a low boiling fraction and a high boiling fraction, and subjecting the low boiling fraction to HF alkylation with an isoparaffin.

  • ethylene
  • Silicotungstic acid is used to manufacture ethyl acetate by the alkylation of acetic acid by ethylene: C2H4 + CH3CO2H → CH3CO2C2H5 It has also been commercialized for the oxidation of ethylene to acetic acid: C2H4 + O2 → CH3CO2H Methylation is the most common type of alkylation, being associated with the transfer of a methyl group.

  • R4} _{{quaternay \atop ammonium} \atop cation}+\underbrace {X^{-}} _{halide \atop anion}} _{quaternay\ ammonium\ salt}}}} Amines and ammonia are generally sufficiently nucleophilic to undergo direct alkylation, often under mild conditions. (wikipedia.org)
  • Therefore, for laboratory purposes, N-alkylation is often limited to the synthesis of tertiary amines. (wikipedia.org)
  • N-alkylation is a general and useful route to quaternary ammonium salts from tertiary amines, because overalkylation is not possible. (wikipedia.org)
  • Isomerization
  • Heterogeneous catalysis employing the use of solid acids plays a key role in accomplishing this target through various routes, including isomerization, alkylation, and reforming. (rsc.org)
  • synthesis
  • The Enders SAMP/RAMP hydrazone alkylation begins with the synthesis of the hydrazone from a N,N-dialkylhydrazine and a ketone or aldehyde The hydrazone is then deprotonated on the α-carbon position by a strong base, such as lithium diisopropylamide (LDA), leading to the formation of a resonance stabilized anion - an azaenolate.
