Abstract

IT is just a hundred years ago since carbon dioxide was first solidified by Thilorier. Most chemists are familiar with carbon dioxide 'snow’, which has long found use in the laboratory as a convenient means of producing temperatures down to about –80° C. The comparatively small quantities required for such purposes were obtained by the simple but wasteful method of allowing liquid carbon dioxide from a cylinder to expand through a valve into a collecting bag; in these circumstances less than 30 per cent of the weight of the liquid used is obtained in the form of ‘snow’.
