Application

Ethanol (190proof) may be used as an extractant for the isolation of flavonoids and chlorogenic acid from dried leaves and stems of Cryptocarya alba.

General description

The product is a 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.
