In an improved process for the separation of alcohols and phenols as borate esters from other volatile substances, transesterification with butyl borate is carried out in a solvent such as methyl cyclo hexane which forms an azeotrope with butyl alcohol. The boratization of soluble hydroxylic compounds proceeds quickly to an easily recognized completion. Trilinalyl borate has been prepared by this method and is pyrolysed only above 150°. The application of the new procedure to the isolation of geijerene from the essential oil of Geijera parviflora Lindley is described.
