Descripción general

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.[1] The impact of ethanol/water fumigation on the performance of diesel engines has been studied.[2] Anhydrous grade solvents show extremely low percentage water and low residue levels.

Aplicación

Ethanol has been used:
  • as a solvent for lovastatin.[3]
  • as a solvent during the synthesis of (S)-4-hydroxy-2-keto-4-(2′-pyridyl)butyrate.[4]
  • to fix tissue sections on a slide during laser capture microdissection (LCM).[5]
