Abstract: A method for preparation of polyols from an unsaturated TAG oil that involves first epoxidizing the unsaturated TAG oil; then subjecting the epoxidized TAG oil to transesterification using a diol and/or triol in the presence of a catalyst to produce hydroxyalkyl esters of fatty acid epoxides; and finally hydroxylating the transesterification product using a diol and/or triol and a solid acid catalyst to obtain a polyol with relatively high hydroxyl value and low viscosity.

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: 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.

Abstract: Improvements are made in the process wherein Li.sup.+ values are recovered from dilute aqueous solution by the use of an anion exchange resin composite containing crystalline LiX.2Al(OH).sub.3, where X is halide. The improvements derive from enriching the Li.sup.+ containing solution with a non-competing metal salt (e.g., NaCl) prior to the Li.sup.+ removal, thereby achieving higher Li.sup.+ loading of the resin composite and obtaining more concentrated eluates.

Abstract translation: 在通过使用含有结晶LiX.2Al（OH）3的阴离子交换树脂复合物（其中X为卤化物）从稀水溶液中回收Li +值的方法进行改进。 这些改进源于在Li +去除之前用非竞争性金属盐（例如NaCl）富集含Li +溶液，从而实现树脂复合材料的更高的Li +负载并获得更多的浓缩洗脱液。
