An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.

52 Method of reacting carboxylic acids US10659738 2003-09-11 US07279082B2 2007-10-09 Paul Watts; Stephen John Haswell
A carboxylic acid molecule (R COOH) is subjected to an electric field in a micro-reactor. The molecule decarboxyles to form a radical (R•). Two radicals (R•) can dimerise to form the product (R—R). It is believed that the reaction occurs away from the electrodes used to apply the electric field (but may also occur at the electrode surfaces).

55 Acid catalyzed isomerization of substituted diaryls US09531248 2000-03-21 US06433236B1 2002-08-13 David Anthony Schiraldi; Alexei Viktorovich Iretski; Sheldon Christopher Sherman; Laren Malcolm Tolbert; Mark Gilmore White
A substituted diaryl compound or a mixture of substituted diaryl compounds, such as dimethylbiaryl compounds are isomerized by treatment with a strong acid or mixtures of strong acids in the absence of any additional catalyst. The strong acid or mixture of acids has a Hammett acidity of less than about −12.6. The isomerization reaction conditions such as reaction temperature, amount of acid, and amount of solvent can be adjusted to selectively produce desired isomers in high yields. One or more desired isomers may be produced in high yields by isomerization of substituted diaryl compounds and selectively removing one or more desired isomers from the resulting equilibrium mixture of isomers. The isomer mixture may be re-isomerized subsequent to selective removal of the desired isomer to produce additional amounts of desired isomer. The isomerization may be employed to substantially reduce the amount of at least one isomer substituted in the 2-position or to substantially increase the amount of at least one isomer substituted in at least the 3-position, the 4-position or the 4-position for the production of at least substantially linear or crystalline polymers.
