ABSTRACT:
The water is heated to convert it into steam; the steam is passed from a container into a superheating zone and then condensed in the form of purified water. The superheating zone contains at least in part, a packing of a material inert with respect to steam and impurities possibly present in the latter. The steam is superheated in said zone by means of supplementary heating to a temperature exceeding 300.degree. C., and reaching notably from 400.degree. to 700.degree. C., preferably from 500.degree. to 700.degree. C. Highly purified apyrogenic water freed from undesired organic substances, useful in research in physical chemistry, physics, biochemistry or molecular biology or in the medical field is, produced by this process.
