摘要:
The invention is directed to a crumbly, water-absorbing, soil-like hydrogel. The hydrogel comprises finely comminuted mineral substances, such as igneous rock; water-soluble alkali-silicate; solid and liquid nutrient additives; and ballast, bound in a cross-linked polymer. The hydrogel is structured like a sponge and absorbs water and liquids when in contact with water or aqueous liquids. The mineral substances present in the hydrogel may be present in an amount of at least 30% by weight of the dried hydrogel. Also, the invention encompasses methods of producing acidic and neutral to weakly alkaline hydrogels.

摘要:
To obtain highly sulfated fatty acids, hydroxy fatty acids or oxalkylated hydroxy fatty acids, the reaction mixture obtained from the sulfatation of unsaturated fatty acid esters and/or saturated hydroxy fatty acid ester and/or oxalkylated hydroxy fatty acid esters is neutralized, optionally separated from the brine, diluted with water and hydrolyzed at a temperature between 20.degree. C. and 160.degree. C. after addition of lye the amount of which at maximum is equivalent to the organically bonded sulfuric acid content. After phase separation from the non-sulfated starting products, the highly sulfated fatty acids are isolated from the aqueous phase.
