Definitions

  • the subject of the present invention is a chemical process for the production of low deuterium content water.
  • Natural water contains 130-160 ppm deuterium (in Hungary 150-154 ppm in average). According to recent discoveries water of lower deuterium content (0.1 - 130 ppm) is suitable for the prevention and treatment of several types of cancer (HU 208,084, FEBS Letters, 1993, 317 (1-2), (1-4).
  • Water of reduced deuterium content is a side product of heavy water production.
  • low deuterium water can be obtained in clean form, in the form of a solution or with varying deuterium content, during the enrichment process (US 2,137,430, GB 435,450, FR 789,822, US 2,044,704, SU
  • light water or light hydrogen suitable to produce light water is formed as a side product of heavy water production in the following methods: isotopic exchange reaction between hydrogen and water (US 2,690,380, US 2,690,379, IT 493,492) isotopic exchange reaction between hydrogen-sulphide and water (US 2,787,526, GB 845, 501, FR 1,165, 257, FR 1,164,750, FR 1,169,140, FR 1,175,894, GB 870,036, CA 616,048,DE 1,047,753), exchange reactions between mercaptanes and water (US 2,741,543, GB 837, 730), isotopic exchange in the mixture of ammonia, hydrogen and water (DE 1,036,223, GB 867,736, FR 1,180,973), as well as exchange reactions between cyclohexane or benzene and hydrogen (US 2,690,380).
  • the main disadvantage of these methods is that in addition to the serious equipment and technical support demand, in the first step - using natural water - the deuterium level decreases only slightly. Moreover, the light water produced has to be submitted to serious purification due to the use of poisonous materials e.g. hydrogen-sulphide, ammonia, etc, in order to make it suitable for human consumption. Disclosure of the invention
  • the fractionation efficiency is three-fold, considering that the water to be fractinated contains 1/3 of the deuterium content of natural water used in the known processes; 4. the starting material applied is a side product;
  • Burning of hydrogen can be carried out directly, in a flameless process,with or without catalyst, in the interaction of air, oxygen or a material containing oxygen.
  • Specific examples of the invention are set forth below. In order that the invention described herein can be more fully understood, the following examples are to illustrate the invention process, however, the examples are for illustration purposes only, and are not to be construed as limiting this invention in any manner. Best mode for carrying out the invention Example 1
  • Example 2 Proceeding as in Example 1 with a sodium-amalgam containing 3% sodium, the reaction mixture was not allowed to heat up (intense cooling) and practically the same result was obtained (51 ppm).
  • Example 3 Proceeding as in Example 1 with a sodium-amalgam containing 3% sodium, the reaction mixture was not allowed to heat up (intense cooling) and practically the same result was obtained (51 ppm).
  • Example 4 Proceeding as in Example 1 with the use of sodium-amalgams of 0.1, 0.5 and 1.0% sodium, the results were practically the same (53,56 and 60 ppm, respectively).
  • Example 4
  • Example 5 Proceeding as in Example 4, but using the hydrogen without deep cooling (the water content was not removed) and carrying out burning in a direct flame in air, the deuterium content of water after condensation was found to be 55 ppm.
  • Example 6 Proceeding as in Example 4, the water vapour formed was introduced to liquid water to cool (without pre-cooling) in counter-current in a column packed with Rasching rings using the dripping method. In this way by mixing the condensed water (55 ppm) and the recycled dripping (cooling) water (154 ppm) in the right rations, water of 130 ppm deuterium content was obtained for use in the food industry.

Abstract

L'eau possédant une teneur limitée en deutérium est utile pour prévenir ou soigner plusieurs types de cancers. Le procédé consiste à fractionner la vapeur d'eau obtenue par combustion directe ou catalytique d'hydrogène à basse teneur en deutérium ou par sa réaction avec des matériaux contenant de l'oxygène, afin d'obtenir de l'eau à teneur limitée en deutérium. L'hydrogène à basse teneur en deutérium s'obtient par mise en réaction d'un métal alcalin, de préférence, un amalgame de sodium obtenu par électrolyse d'alcalis et de chlorure, avec de l'eau naturelle et l'hydrogène généré par le procédé - possédant une teneur en deutérium d'environ 1/3 de celle de l'eau naturelle de départ - est utilisé pour produire de la vapeur d'eau.
