WebEthene is mixed with steam in a fixed molar ratio of ethene/water (1:0.60). The mixture is heated to 300 oC and the gases react over the catalyst to form ethanol. The gaseous mixture of unreacted ethene and product ethanol is cooled down which liquefies ethanol. The product is separated and unreacted ethene is recycled back into the reaction ... Webno catalyst is needed to increase the rate of this reaction since the steam provides the required activation energy To maximize the yield of ethene, by Le Chetalier's Principle : increasing the temperature of the reactions favours the formation of products since the reactions are endothermic.

WebUsing this method, if ethene (an alkene) is added to steam, ethanol (an alcohol) can be formed. In fact, this method is an industrial way of making ethanol. Conditions for the reaction.
