VERFAHREN ZUM HALTEN EINER WÄSSRIGEN LÖSUNG VON NATRIUMBORAT IN FLÜSSIGER FORM BEI RAUMTEMPERATUR

摘要

A method for maintaining a liquid aqueous solution of sodium borate at a storage temperature, in which the solution passes from an initial temperature to the storage temperature, consists of: - (a) subjecting the solution to a thermal treatment including at least one cooling or reheating at a speed of between 1 and 100 deg. C/min, to a maintaining temperature of between -50 and +200 deg. C; - (b) followed by maintaining this temperature for a duration of between 1 second and 100 hours; - (c) followed by a cooling or reheating at a speed of between 1 and 100 deg. C. - An INDEPENDENT CLAIM is also included for the generation of hydrogen by the reaction of sodium boro-hydrocarbide with water and separating the hydrogen and the sodium borate which is then subjected to the liquid maintaining operation.
