The invention relates to Membrane Structured Solid Nanoparticles (MSSNs) and dispersions thereof and uses thereof. These MSSNs have a combination of active compound vehicles and emulsifiers as such to form membranes which infiltrate the entire nanoparticles so that there are emulsifiers in the interior and on the surface of said nanoparticles. The active compound in these structures comprises ultrafine titanium dioxide which is well dispersed and evenly devided therein.

摘要:
The invention relates to a photocatalyst containing titanium dioxide, to a method for using it and to its application. A sulphurous titanium dioxide hydrate precipitate is precipitated from an acid titanium oxysulphate solution at a temperature below the boiling point of the solution, e.g. in the range from 70 to 100°C, using crystal nuclei and without addition of base. The precipitate is separated, washed and calcinated. The photocatalytic titanium dioxide thus obtained has a specific area in the range from 100 to 250 m2/g and a 0.3 to 5% sulphur concentration. Catalytic activity has been confirmed in asetal dehyde decomposition and in anionic (SNC-)2 radical formation.

The invention relates to a process of preparing ferric sulfate by forming a slurry which contains ferrous sulfate and sulfuric acid, the slurry containing bivalent iron in both the solution phase and the solid phase, and by oxidizing this slurry to form a ferric sulfate slurry. When so desired, the obtained ferric sulfate slurry is solidified to form solid ferric sulfate. The obtained ferric sulfate may, as such or dissolved in water, be used for the treatment of waste waters or for preparing pure tap water.
摘要:
The invention concerns a method for treating ferrous sulphate for the preparation of ferrous sulphate hydrate usable for chromium reduction in cement manufacture. According to the invention, sulphuric acid containing ferrous sulphate obtained as a side product from titanium dioxide production and which contains at the most appr. 30 % by weight of sulphuric acid, is neutralized with a CaO-containing material, preferably cement, in an amount sufficient to give a pH-value to the end product which is 1.5 to 5, whereby the reaction temperature is allowed to increase to at the most 120 °C.
摘要:
The invention relates to the use of mixtures and surfactants, which form multilaminar liquid crystalline structures. The surfactants are selected from at least two of the following groups consisting of isethionates, taurates, sarcosinates, acyl lactylates, acyl glutamates, fatty acid protein condensates, PEG stearates, PEG distearates having an HLB value of less than 10, alkyl polyglycosides and of betaines in order to reduce the skin irritant action of cosmetic and/or pharmaceutical formulations that are applied to the skin and to improve hair structure.
摘要:
The invention relates to a method of producing granular material having a high soluble iron(II) content. The method comprises obtaining an amount of a crude precipitate comprising iron(II)sulphate monohydrate and sulphuric acid from titanium dioxide production, and mixing the said precipitate and a neutralising agent in a mixing apparatus to obtain a reaction mixture. The temperature during mixing of the reaction mixture is allowed to increase at the most to a temperature of 120°C. Water is mixed to the reaction mixture in the same mixing apparatus, and the amount of neutralising agent is kept sufficient to give a pH value from 1.5 to 3 to the end product. The invention relates also to a plant for producing granular material, to a product and its uses.
