<p>The invention provides a method and compositions for eliminating water from water-bearing bodies such as parts of vegetals, animals, microorganisms, hydrophilic colloids and gels, etc., by immersing these bodies in a dehydrating solution which contains at least ketone or an alcohol until the water content in the treated body is reduced under 25%; then by removing the newly-absorbed ketone or alcohol and the remaining water through the process of boiling them in an oil solution, keeping the oil solution at high temperature and atmospheric pressure or at low temperature and low pressure until all the ketone or alcohol mentioned and the remaining water have completely evaporated. And if such nonvolatile substances as paraffin with high boiling point, polymer, resin, high molecular fatty alcohol, bee wax, etc. are added to the oil solution, the treated object will keep for a very long period of time in ordinary atmospheric conditions without suffering any noticeable changes.</p> |
