詳細

詳細

Poly [(phenyl glycidyl ether)-co-formaldehyde] (Re₂O₇) is a strong oxidant and a highly selective Lewis acid catalyst. The structure is constituted of strongly distorted ReO₄ octahedra and nearly regular ReO₄ tetrahedra which are connected through corners to form polymeric double layers in the ac plane.

アプリケーション

Re₂O₇ acts as a catalyst in the heteroacylative dimerization of THF.Adhesives, structural and electrical laminates and coatings and castings for high temperature service.

特徴および利点

Good chemical resistance at high temperatures. Substitutes for Bisphenol A and phenolic epoxy resins.

物理的形状

Oligomeric epoxide.
