摘要： The present invention provides organofunctional siloxane coupling agents, dipodal siloxanes, siloxane block copolymers and a specific method for preparing these organofunctional siloxanes through an addition reaction of hydrido alkoxysilane and organofunctional disiloxanes to an organocyclosiloxane with a catalyst. The addition reaction of the current invention does not result in polymerization and therefore the novel siloxane couplings agents are free of cyclosiloxanes and polymeric siloxanes. This makes them apt for adhesives, coatings and sealant applications. The present invention also relates to the use of these organofunctional siloxane compounds for the treatment of fillers and surfaces.

摘要： When a disproportionated chlorosilane is to be produced by causing a starting material chlorosilane liquid to flow through a catalyst-packed layer which is packed with a weakly basic anion exchange resin as a disproportionation reaction catalyst to carry out a disproportionation reaction, before the disproportionation reaction is carried out, the disproportionation reaction catalyst is brought into contact with a processing gas obtained by diluting a chlorosilane with an inert gas to prevent the deterioration of the disproportionation reaction catalyst at the start of the reaction so as to carry out the disproportionation of the chlorosilane efficiently.

摘要： A method for producing adamantane includes the steps of preparing a catalytic composition including an acidic ionic liquid and a co-catalyst and subjecting a tetrahydrodicyclopentadiene-containing component to isomerization in the presence of the catalytic composition to form adamantane. The acidic ionic liquid includes aluminum chloride and a quaternary onium compound selected from the group consisting of a quaternary ammonium halide, a quaternary phosphonium halide, and a combination thereof. The co-catalyst is an oxygen-containing reagent.

摘要： Provided is a method for preparing levulinic acid using a solid acid catalyst in the presence of an ethylene glycol-based compound. The levulinic acid according to the present invention can be prepared by using a linear or cyclic ethylene glycol-based compound as a solvent and preparing the levulinic acid from fructose in the presence of the solid acid catalyst at a reaction temperature of 100 to 200° C., thereby reducing the dependency on petroleum in response to greenhouse gas emission regulations. Also, a high yield of levulinic acid can be obtained from fructose, and the solvent and the catalyst can be efficiently separated, collected, and reused after the reaction has completed.
