Reflux oxidation of ethanol
WebReflux apparatus is when a distillation tube is surrounded by an apparatus that pumps cold water around it in order to condense its compounds in the mixture. As ethanol has a low boiling point, it evaporates fairly quickly.This means some of the ethanol may escape before it has been fully oxidised ino a carboxylic acid. Reflux therefore allows ...

Webdistillation system, in which a batch of beer, with the heavy solids (spent grain) not removed, is simply boiled in place to vaporize the alcohol. The alcohol-water vapors are then forced to flow through a distillation column to bring about concentration. These two processes are discussed in detail in the following Webdescription
