200 proof, HPLC/spectrophotometric grade, Linear Formula: CH3CH2OH, Molecular Weight: 46.07, Synonym: Ethanol, absolute alcohol, non-denatured ethanol. BP: 78.3 °C, MP: -114 °C. 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. Spectrophotometric grade solvent is of high purity with low UV absorption.
