General description

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

Application

Dibutyl ether may be used to compose the solvent mixtures in the following studies:
  • To evaluate the anthracene solubility in various binary solvent mixtures composed of dibutyl ether along with n-hexane, cyclohexane, n-heptane, methylcyclohexane, n-octane, isooctane and cyclooctane.
  • To measure the pyrene solubility in various binary solvent mixtures composed of dibutyl ether along with n-hexane, cyclohexane, n-heptane, methylcyclohexane, n-octane, isooctane and tert-butylcyclohexane.
  • To investigate the reaction mechanism and kinetic studies of the reaction of phenyl isocyanate with methanol in the presence of dibutyltin diacetate (catalyst) to afford urethane. Rate constant of the reaction, k was reported to be 0.96liter/(mole sec).
