Description

General description

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

Application

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

Preparation Note

Product filtered through a 0.2 μm filter
