The present invention relates to a process for preparing high-functionality polyethers having a Hazen color number of less than 500, by converting tris(hydroxyethyl) isocyanurate (THEIC) and one or more difunctional alcohols and/or modifying reagents with the aid of acidic catalysts. The present invention further relates to high-functionality polyethers having a color number of less than 10, obtainable by such a process, and to the use of these high-functionality polyethers as adhesion promoters, thixotropic agents, rheology modifiers of polymers, in printing inks, paints and coatings, or as units for preparation of polyaddition or polycondensation polymers.

The present invention provides an amphiphile of the formula (I) as described hereinafter. The invention further relates to a process for preparing the amphiphile and to a composition comprising the amphiphile and a sparingly water-soluble active ingredient. It further relates to a process for producing the composition by contacting the amphiphile and the active ingredient, and to the use of the amphiphile for solubilizing a sparingly water-soluble active ingredient in aqueous solutions. The invention also relates to the use of the amphiphile in an agrochemical formulation comprising the amphiphile and a pesticide for controlling phytopathogenic fungi and/or unwanted vegetation and/or unwanted insect or mite infestation and/or for regulating the growth of plants, and finally to plant propagation material comprising the amphiphile.
摘要:
Described is a metal oxide support material containing nanoscaled iron-platinum group metal particles having a particle size in the range of 0.5 to 10 nm. At least 70% of the nanoscaled iron-platinum group metal particles are located on an outside surface layer of the metal oxide support material. The outside surface layer has an average volume of less than 50% based on the total volume of the metal oxide support material. Additionally, described is a process for preparation of metal oxide support materials containing nanoscaled iron-platinum group metal particles. Furthermore, described is the use of metal oxides containing nanoscaled iron-platinum group metal particles as catalysts, for example as a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine.
