Description

General description

Dibutyl ether is being considered as an alternative fuel for diesel engines due to its non-miscibility in water, high cetane number and energy content.

Dibutyl ether is commonly used as solvent for various reactions. It forms azeotropic compositions with various organic solvents and the vapour/liquid equilibria of its binary mixtures have been investigated by head-space gas chromatography.

Application

Dibutyl ether may be used as a solvent for the synthesis of tricarbonyl[(1,2,3,4-η)-1- and 2-methoxy-1,3-cyclohexadiene]iron by the reaction of 1-methoxy-1,4-cyclohexadiene with iron pentacarbonyl.
