  • This invention relates to methods and compositions used to eliminate water from water-bearing bodies such as parts of vegetals, animals, microorganisms, hydrophilic colloids and gels, . . . with the choice of whether or not substituting the removed water with nonvolatile substances.
  • Examples of such methods are: drying by high temperature, drying by low pressure, by refracted ray, by microwave, by the use of desicating substances, by lyophylization, boiling the water of water-bearing bodies in hot oil, directly boiling the water of water-bearing bodies in hot oil with low pressure, dehydrating the water-bearing body using an alcoholic solution then drying it in dry air in high temparature or drying it in low temperature and low pressure, dehydrating the water-bearing body using an alcoholic solution then washing the newly-absorbed alcohols with low-solubility substances (e.g. toluen, xylen) then finally drying it in dry air in high temparature or drying it in low temperature and low pressure.
  • low-solubility substances e.g. toluen, xylen
  • the new invention provides a new method and compositions capable of overcoming the above-mentioned failings with the following features: the water eliminating process takes little time; the product retains its initial form after the process. This method is consequently applicable to all types of bodies with a high proportion of water, especially the ones with thick section. Besides this method also allows substituting or not the space left by the lost water in the product with nonvolatile substances, this way, the product will retain its form and fresh appearance and be preserved for a long period of time in ordinary atmospheric conditions.

  • the new 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 to under 25% (preferably under 5%); then by removing the newly-absorbed ketone or alcohol and the remaining water through the process of boiling them in an oil solution (the preferred oils are oils with boiling points above 70 °C, having the solubility of water in them under 30% at room conditions), 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.
  • Bodies or products containing a high proportion of water such as parts of vegetals, organs or parts of animals, microorganic tissues, hydrophilic colloids or gels, etc., are immersed in a solution of dehydrating elements comprising at least one of the following:
  • the time of immersion depends on the thickness of the body's section and varies from a few minutes to a few days, lasting until the water content left in the treated body is preferably less than 10%, the most part being replaced by the dehydrating substances.
  • the next step is to remove these dehydrating substances (ketone or alcohol) and the remaining water by boiling them in an oil solution having the following characteristics: boiling point above 70 °C; solubility of water in this oil solution under 30% as to the volume of the oil solution.
  • dehydrating substances ketone or alcohol
  • the preferred temperature and pressure for boiling the newly-absorbed ketone or alcohol in the treated body are respectively 20 °C - 110°C and 20 mmHg - 760 mmHg.
  • Nonvolatile substances with boiling points over 180°C and having the solubility of water in them under 20% can be mixed to the oil solution for the purpose of replacing the removed water from the water-bearing bodies.

The then dead worm is taken out and put in a solution of 60% acetone and 40% methyl ethyl ketone for 12 hours at room temperature. Next the worm is taken out and put in another solution composed of 30% cethyl alcohol, 20% branched paraffin with carbon number 12 - 25, and 50% xylene; the temperature and pressure of the solution are respectively 55 °C and 150 mmHg; the time of immersing and boiling is 10 minutes. Then the worm is kept in the same solution for 5 other minutes at the same temperature of 55 °C but the pressure is raised to 760 mmHg. Finally the sea worm is removed from the solution and dried at temprature of 60 °C, room pressure, for 5 hours. The dried worm retains its fresh living-looking appearance and can be preserved in normal conditions for a very long time.

Then take the cube of gelatine from the solution and put it in xylene at temperature of 55 °C and pressure of 100 mmHg for 30 minutes in order to boil all the acetone absorbed by the gelatine. Finally take the cube of gelatine out and dry it at temperature of 55 °C , pressure of 100 mmHg for 6 hours. The final product is a cube of open cell foam that still keeps its initial shape.

Abstract

L'invention concerne un procédé et des composition pour l'élimination de l'eau de corps contenant de l'eau, tels que, entre autres, des parties de végétaux, d'animaux, de micro-organismes, de colloïdes hydrophiles et de gels, par immersion desdits corps dans une solution déshydratante qui contient au moins de la cétone ou un alcool, jusqu'à ce que la teneur en eau du corps traité soit réduite à moins de 25 % ; par élimination de la cétone ou de l'alcool récemment absorbée et de l'eau restante, par la mise en ébullition de ceux-ci dans une solution huileuse maintenue à une température et à une pression atmosphérique élevées ou à une température et à une pression faibles, jusqu'à ce que toute la cétone ou tout l'alcool et l'eau restant se soient complètement évaporés. Si des substances non-volatiles telles que la paraffine à point d'ébullition élevé, du polymère, de la résine, un alcool gras à poids molaire élevé, de la cire d'abeilles, etc, sont ajoutés à la solution huileuse, l'objet traité se conservera très longtemps dans des conditions atmosphériques ordinaires, sans altération sensible.
