ALCOHOLS ALCOHOLS •Family of organic compounds that all contain the -OH functional group •This is the group of atoms responsible for their chemical properties and reactions HYDRATION OF ETHENE •A mixture of ethene and steam is passed over a hot catalyst of phosphoric acid at a temperature of 330°C •The pressure is used 60-70 atmosphere •The gaseous ethanol is then condensed into a liquid for use HYDRATION OF ETHENE Ll 075 | HH ETHENE oP H,0 (g) = H3 PQ, op STEAM 300°C & 60atm Fsave ETHANOL FERMENTATION Fermentation of glucose Sugar or starch is dissolved in water and yeast is added The mixture is then fermented between 15 and 35°C with the absence of oxygen for a few days Yeast contains enzymes that break down starch or sugar to glucose If the temperature is too low the reaction rate will be too slow and if it is too high the enzymes will become denatured
