Abstract: Un proceso para preparar partículas recubiertas con sílice de un agente expansor inorgánico, las partículas recubiertas con sílice y su uso. Las partículas recubiertas con sílice muestran una liberación demorada del agente expansor, en particular en medio alcalino y a temperaturas elevadas. Por lo tanto, son útiles en la industria del petróleo y de la construcción.

Abstract: The invention relates to a method for the preparation of a hyperbranched polyester mixture obtainable by reacting a hydroxyl group containing carboxylic acid (B) with at least one carboxylic acid group and at least two hydroxyl groups with a diol (C) having a molecular weight of more than 100 g/mol, optionally in the presence of at least one further reactant, wherein the at least one further reactant is a polyol (A) having at least three hydroxyl groups under a reaction condition allowing ester and ether formation; and reacting the mixture resulting from step (a) with a hydrophobic carboxylic acid (D) resulting in the hyperbranched polyester mixture. The invention further relates to said hyperbranched polyester mixture and the use as wax inhibitor, as pour point depressant, as lubricant or in lubricating oils.

Abstract: Coated inorganic expanding agent particles comprise a core of an inorganic expanding agent and a sol/gel-formed coating comprising a mixed oxide of two or more metals and/or metalloids, in particular a mixed oxide of silicon and at least one metal and/or metalloid selected from aluminum, boron, titanium, zirconium and zinc. The coated inorganic expanding agent particles are added to cementitious systems to avoid shrinkage during hardening. The coating is effective to delay the expanding effect.

Abstract: The invention relates to a process for preparing silica-coated particles of an inorganic expanding agent, the silica-coated particles and their use. The silica-coated particles show a delayed release of the expanding agent particularly in alkaline medium and at elevated temperatures. They are therefore useful in the oil and construction industry.

Abstract: The invention relates to a method for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation, which method comprises the step of adding a first amine to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture, wherein the first amine (A) is a compound of formula I (I),a salt of a protonated compound of formula I and a first anion or a mixture thereof. A second amine, which is a compound of formula II (II), a salt of a protonated compound of formula II and a second anion or a mixture thereof, can be further added. Furthermore, a specific composition of the first amine (A) and the second amine (B) for a use as a flotation collector is described.

Abstract: The present invention relates to the use of a composition for stabilizing a geological formation in oil fields, gas fields, water pumping fields, mining or tunnel constructions. The composition has a hardening temperature in the range from about 40 °C to about 120 °C and can therefore be used to stabilize a geological formation in oil fields, gas fields, water pumping fields as well as in mining or tunnel constructions.
