Beschreibung

Anwendung

The acid selectively blocks dye components from staining the tissue by either binding to it or by acting as a mordant. It may be used a recyclable superacid catalyst for isomerization reaction of cycloalkanes. It may simply be used as an acid catalyst for the following reactions:

• Prins cyclization reaction
• dehydration of alcohols
• hydration of olefins.3

Phosphotungstic acid based membranes may be used for fuel cell applications.
