Description

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.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". 

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).
