Description

General description

Prices include Federal Tax.

Pure ethyl alcohol is a non-denatured 190proof 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. Spectrophotometric grade solvent are of high purity grade with low UV absorption.
