Application

Methylcyclohexane may be used as a solvent for the synthesis of unsolvated n-butylmagnesium chloride by the reaction of 1-chlorobutane with magnesium powder. It may also be used as the starting material to synthesize 1-methylcyclohexanecarboxylic acid.

Pharmaceutical intermediates. Methylcyclohexane is an important organic solvent and extractant, which can be used as a solvent for rubber, paint, varnish (some paint solvents also use methylcyclohexane), and can be used as oil extractant. Methylcyclohexane can be used in organic synthesis as solvent and analytical reagent. In addition, methylcyclohexane can also be used as a standard for thermometer calibration. The correction solution is usually made of methylcyclohexane as the main component.

General description

N,N-Diisopropylethylamine, also known as Hünig′s base, is a sterically hindered amine. It is a non-nucleophilic base commonly employed for substitution reactions.It acts as an activator for chiral iridium N, P ligand complexes, which can be utilized in the hydrogenation of α, β-unsaturated nitriles. The influence of varying concentration of N,N-diisopropylethylamine on the synthesis of olvanil in the presence of lipase catalyst has been investigated.
