2-Aminobenzyl Alcohol

Sigma-Aldrich Supelco

2-Aminobenzyl alcohol is oxidatively cyclized with an array of ketones in dioxane at 80°C in the presence of a ruthenium catalyst and KOH to give corresponding quinolines. It undergoes oxidation catalyzed by heterotrimetallic RuMnMn species on the hydrotalcite surface in the presence of O2 to yield 2-aminobenzaldehyde

Methanol for HPLC, ≥99.9%

Sigma-Aldrich Supelco

Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al2O3 catalysts. It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature. In a direct methanol fuel cell (DMFC), methanol undergoes oxidation with air to generate electr…
