Preparation of solid acid of sulfated binary metal oxides via solid-liquid interface reaction

Autor: Hiromi Matsuhashi, Reiko Onoki, Kana Yoshida, Yuuki Nishiyama

Solid acid catalysts composed of sulfated binary metal oxides, SO42–/TiO2–ZrO2, SO42–/Fe2O3–Al2O3, SO42–/ZrO2–Al2O3, and SO42–/Al2O3–ZrO2 were prepared via a solid-liquid interface reaction of the corresponding hydrated metal sulfates

Synthesis of solid acid catalysts of MgO–Al2O3 mixed oxide containing oxyanions by thermal decomposition of anion-exchanged hydrotalcites

Autor: Hiromi Matsuhashi

Solid acid catalysts of MgO–Al2O3 mixed oxides containing B4O72−, HPO42−, Mo7O246−, MoO42−, WO42−, and SO42− were synthesized by anion exchange with Cl− located in the space between anionic layers of hydrotalcite, followed by heat tre

Preparation of active MgO by short-time thermal decomposition of Mg(OH)2

Autor: Jun Ichikawa, Michiko Kitagawa, Sayaka Misu, Hiromi Matsuhashi

Publikováno v: Research on Chemical Intermediates. 41:9463-9473

In the preparation of MgO, Mg(OH)2 was placed in a muffle furnace maintained at a desired temperature for rapid increase to the activation temperature and for short-time heating. The MgO obtained showed a higher activity for the retro-aldol reaction
