Beschreibung

Allgemeine Beschreibung

Thermochemical conversion of methanol to C₂-C₁₀ hydrocarbons in the presence of shape-selective zeolites has been reported.[1] Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.[2]

Anwendung

Used as a solvent in:

• Preparation of self-assembled monolayers (SAMs) of sulfur derivatives with bactericidal terminal fragments on gold surfaces prior to analytical characterization
• Measurement of soluble absorption spectra of PTFE samples
