In the production of ethanol by the hydrolysis of ethylene, diethyl ether is produced as a byproduct. A typical feed stream composition is 55% ethylene, 5% inserts, and 40% water. A typical product stream is 52.26% ethylene, 5.49% ethanol, 0.16% ether, 36.81% water, and 5.28% inserts. Calculate the selectivity of ethylene for ethanol and for ether.
