Description générale

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.
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


  • Monitoring and evaluation of alcoholic fermentation processes using a chemocapacitor sensor array.: Ethyl alcohol is studied not just as a product but also as an analytical tool in monitoring fermentation processes. This work illustrates the integration of sensor technology with chemical analysis, highlighting advancements in analytical techniques for monitoring and quality control in the beverage industry (Oikonomou et al., 2014).

  • Ancient nigella seeds from Boyali Höyük in north-central Turkey.: Utilizing ethyl alcohol in the conservation and analysis of ancient botanical remains, this historical study reflects the critical role of analytical chemistry in archaeological research, providing insights into ancient agricultural practices (Salih et al., 2009).
