PROCESS FOR THE EASIER PURIFICATION OF VALUABLE MATERIALS AND/OR THEIR MIXTURES IN THE FIELD OF WETTING, WASHING AND/OR CLEANING AGENTS AND RELATED SUBSTANCES

摘要

The present invention relates to a kind of quality for improving purity and especially in color and smell utility and mixture of useful materials, in wetting, washing and/or cleaning agents. In this process, which includes that impurity especially water vapour volatile impurity finely divided form processing has about normal pressure overheat steam, and wherein bleaching agent can enhance with the material color. In a specific embodiment, the present invention relates to be used to dry aqueous preparations precious materials and/or its mixture for this method, in wetting agent, the additional superheated steam of the spray region and/or backset bed of detergent and/or cleaning agent make cleaning substance pollution while dry gas especially with the volatile impurity of vapor. The cleaning can be dissolved with oxidation or reducing bleach simultaneously to obtain bright coloured valuable material general idea or their mixture. If necessary, drop ozone superheated steam can be added.
