    Abstract: The present invention provides a technique which allows stable use of an ion-exchange resin for removing boron impurities over a long period of time in the purification step of a silane compound or a chlorosilane compound. In the present invention, a weakly basic ion-exchange resin used for the purification of a silane compound and a chlorosilane compound is cleaned with a gas containing hydrogen chloride. When this cleaning treatment is used for the initial activation of the weakly basic ion-exchange resin, a higher impurity-adsorbing capacity can be obtained. Further, use of the cleaning treatment for the regeneration of the weakly basic ion-exchange resin allows stable use of the ion-exchange resin for a long time. This allows reduction in the amount of the resin used in a long-term operation and reduction in the cost of used resin disposal.

    Abstract: A method releases hydrogen by forming a second ionic liquid from a first ionic liquid by releasing hydrogen from the first ionic liquid by exposing the second ionic liquid to water and a catalyst. The first ionic liquid includes a cation and an anion including a borohydride. The release of the hydrogen forms a borate, which makes up the anion of the second ionic liquid. The cation of the first ionic liquid is the same as that of the second ionic liquid. A reaction system includes the first and second ionic liquids, water and a catalyst.

    Abstract: The present invention relates to mixed-modal anion-exchange materials composed of a support on which a ligand is immobilized. The ligand combines at least one basic domain based on cyclic monobasic derivatives with two or more rings as anion-exchange domain and at least one non-ionic binding domain. The basic domain is ionized under the conditions of use and may contain secondary, tertiary, or quaternary nitrogen forming a weakly (WAX) or strongly (SAX) basic anionic exchange domains. The non-ionic binding domain allows adjustment of the overall hydrophobicity/hydrophilicity of the material and represents a second binding site for the solute to be separated. Binding to this second binding site is based on reversed phase (RP), hydrophobic interaction (HIC) or hydrophilic interaction (HILIC). Linker sites, which can be represented by a chemical bond or by hydrophobic moieties like alkyl(ene) chains or hydrophilic moieties like amide structures connect the support to the binding domains and the binding domains to each other.
