Abstract: The invention relates to a process for producing a catalyst comprising an intermetallic compound comprising following steps: (a) Dissolving a metal selected from the group consisting of Li, Na, Ca, Sr, Ba, Eu and Yb in liquid ammonia, (b) Adding nanoparticles comprising a metal selected from the group consisting of Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au and Ru or a halide of at least one of these metals and an inorganic salt to the solution obtained in step (a), (c) Removing the liquid ammonia, (d) Annealing the mixture of step (c) at a temperature in the range between 200° C. and the melting temperature of the intermetallic compound wherein the intermetallic compound is formed, (e) Washing the intermetallic compound achieved in step (d). The invention further relates to a catalyst obtained by the process.

Abstract: The invention relates to a process for preparing core-shell particles having a polymer core and a continuous silica shell. The in situ formed core-shell architecture suppresses film formation of the polymer and simplifies the subsequent drying process. The finally obtained free flowing polymer powder exhibits improved redispersibility and storage stability and imparts building material compositions improved viscosity and faster skin-forming time.

Abstract: The invention relates to aprocess for producing a catalyst comprising an intermetallic com-pound comprisingmixing of a salt comprising a metal selected from the group consisting of Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Auand Ru, a salt comprising a metal selected from the group consist-ing of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba,Sc, Y, La and the lanthanides, and a reducing agentcomprising a salt,wherein the mixing is carried out at a temperature where all compo-nents are solid; reacting the mixture obtained to form an intermetallic compound by heating said to a temperature in the range between the melting temperature of thereducing agent and the melting temperature of the intermetallic compound and holdingthe temperaturefor1 minute to 600 minutes; and washing the mixture to removeby-products andremainders of the salt of the cations of the reducing agent and at least one of the anions of the salts used in the first step. The invention further relates to a catalyst obtained by the process.

Abstract: The present invention relates to coated polymer particles comprising a water-swellable polymer core and an essentially continuous coating encapsulating the core. The coating comprises an oxide, hydroxide or oxide hydrate of silicon, aluminum, zirconium, tin or titanium. The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.
