FORFARANDE FOR FRAMSTELLNING AV VATTENOLOSLIGA RONTGENAMORFA ALUMINIUMSILIKATER SOM INNEHALLER BUNDET VATTEN OCH BUNDNA TENSIDER

摘要

An improved process for the production of tenside-containing aluminosilicates having cation exchange capacity by precipitating the same from aqueous solutions of alkali metal silicates and alkali metal aluminates in the presence of ionic surface-active compounds from the group consisting of anionic surface-active compounds, cationic surface-active compounds and zwitterionic surface-active compounds, wherein the excess alkalinity is neutralized by conducting said process in the presence of an acid aluminum salt such as aluminum sulfate, aluminum nitrate and aluminum chloride.
