General description

Pure ethyl alcohol is a non-denatured 200proof ethanol. Ethanol, a primary alcohol, is an important raw material for the synthesis of various compounds. It can be synthesized either from molasses by fermentation or by hydration of ethylene. It acts as a hydrogen source and reaction medium during the transfer hydrogenation of carbonyl compounds in the presence of sodium hydroxide. The impact of ethanol/water fumigation on the performance of diesel engines has been studied. Anhydrous grade solvents show extremely low percentage water and low residue levels.

Application

Ethanol has been used:
  • as a solvent for lovastatin.
  • as a solvent during the synthesis of (S)-4-hydroxy-2-keto-4-(2′-pyridyl)butyrate.
  • to fix tissue sections on a slide during laser capture microdissection (LCM).
