Also, there was reduced performance with substrates that have low reactivity (those having electron-groups at position 3 on the ring), because they do not carry out the
alkylation well.

alkylation of thiophenic sulfur in FCC gasoline using La2O3-modified HY zeolite", Catalysis letters, 127: 70-74 (2009).
The main goal of the present study was to optimize the hydrazine
alkylation reaction.
Alkylation of toluene with methanol produces primarily a mixture of xylenes the distribution of which in the product largely depends on the characteristics of the catalyst.
Pilot Chemical also focuses on
alkylation, distillation, amidization and custom blending for specific and targeted applications.
Among the topics discussed are principles of reactor design and control, designing and controlling an auto-refrigerated
alkylation process, and the ethyl benzene process.
The cross-linking of BUR with nitrogen nucleophiles involves
alkylation by allylic bromide, followed by deprotonation of the resulting ammonium bromide sail to give an allylic amine intermediate (Scheme 1; R(1)=H).
To give you an example of these problems, the paper on this tenofovir work mentions that the phosphate
alkylation seems to work best with magnesium t-butoxide, but that the yield varies from batch to batch, depending on the supplier.

Among these, ILs have recently classified into five types namely
alkylation ILs, metathesis ILs, protic ILs, eutectic ILs and protic eutectic ILs.
London, Oct 4 (ANI): Researchers have discovered a new mechanism that detects and repairs a common form of DNA damage called
alkylation.
The upgrade also added a 200,000 bpd vacuum distillation unit, a 92,000 bpd catalytic cracking unit and a 26,000 bpd
alkylation's unit.
The section Existing
Alkylation Process and Waste Management below introduces the process--alkylation--concentrating on the management of fluoridic waste arising from HF used as catalyst.
The gas leak, in 2003, saw 20 tonnes of isobutane, mixed with 150kg of hydrogen fluoride (HF), escape into the atmosphere from the HF
alkylation plant.
On May 29, 2003, 20 tonnes of isobutane (LPG), mixed with 150 kg of hydrogen fluoride escaped into the atmosphere from a corroded pipe in the HF
alkylation plant.
