Retention parameters of alkyl tert-butyl ethers have been measured by gas chromatography using stationary phases of various polarity. The stationary phase polarity influences elution order of a pair alcohol/ether as well as their resolution degree. Dependence of log Vg vs boiling temperature of the ethers is linear within a given homologous series of compounds except for the first two members. The retention times of ethers and alcohols have been found to coincide when using di-n-heptyl phthalate as stationary phase.
