Abstract

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 150ยฐ. The application of the new procedure to the isolation of geijerene from the essential oil of Geijera parviflora Lindley is described.

An improved procedure to isolate mitochondria from chick pectoralis muscle is described. The muscle is digested with the proteinase Nagarse and homogenized using a Teflon pestle. Mitochondria are isolated by differential centrifugation. These organelles are able to utilize a variety of substrates wi
