    Abstract: Recently, silica is often blended in energy-saving tires. Since a reaction between silica and a silane coupling agent is slow, kneading is performed in multiple stages and so on. In order to simplify the kneading step, provided are a rubber composition and a filler for use in rubber, both of which have excellent workability and dynamic characteristics. More specifically, provided are a filler composition containing a silica-based filler, a silane coupling agent, and a hydroxy acid and/or a hydroxy acid salt; a filler obtained by reacting the filler composition; a rubber composition containing the filler; a crosslinked product of the rubber composition; a composition containing a diene-based rubber, silica, a silane coupling agent, and a hydroxy acid and/or a hydroxy acid salt; and a crosslinked product of the composition.

    Abstract: Provided is a chlorine dioxide-generating product comprising an inorganic porous carrier carrying a chlorite and an alkali agent. In the product, the alkali agent is carried in an amount of more than 0.7 molar equivalent and not more than 2 molar equivalents relative to the amount of the chlorite carried, and the product has a water content of 10% by weight or less. The chlorine dioxide-generating product can stably generate chlorine dioxide gas in an amount that sufficiently achieves deodorization, sterilization, virus removal, mold prevention, antisepsis, or the like of spatial environments, foods, or others but exerts no harmful effect on humans, over a long period of time.

    Abstract: 2-Aryl-2-halomethyl-4-chloromethyl-1,3-dioxolane (A) is produced with ease without decreasing the optical purity, by reacting optically active monochlorohydrin and aryl(halomethyl)ketone as starting materials in an acid catalyst. Furthermore, optically active (2-aryl-2-halomethyl-1,3-dioxolan-4-yl)methyl carboxylate and optically active (2-aryl-2-halomethyl-1,3-dioxolan-4-yl)methyl sulfonate, which are useful intermediates for ketoconazole, are efficiently produced from the obtained optically active form (A).
    In addition, optically active trans-(2-aryl-2-halomethyl-1,3-dioxolan-4-yl)methyl carboxylate is isomerized to a cis form thereof in the presence of an acid catalyst.

    Abstract translation: 通过使光学活性的一氯醇和芳基（卤代甲基）酮作为原料在酸催化剂中反应，可容易地制备2-芳基-2-卤代甲基-4-氯甲基-1,3-二氧戊环（A）而不降低光学纯度。 此外，还优选光学活性的（2-芳基-2-卤代甲基-1,3-二氧戊环-4-基）甲基羧酸酯和光学活性的（2-芳基-2-卤代甲基-1,3-二氧戊环-4-基） 从得到的光学活性体（A）有效地制造作为酮康唑的有用中间体的化合物。 另外，在酸催化剂存在下，将光学活性的反式 - （2-芳基-2-卤代甲基-1,3-二氧戊环-4-基）甲基羧酸酯异构化为其顺式。
