WebEthanol is made by hydration of ethene (CH 2 =CH 2 ). This is the easiest and most cost-effective method to manufacture ethanol. Ethene is a product of the petroleum industry and thus is an easily available raw material. The reaction is carried out in the presence of phosphoric acid (H3PO4) used as a catalyst.
WebThis page looks at the manufacture of alcohols by the direct hydration of alkenes, concentrating mainly on the hydration of ethene to make ethanol. It then compares that method with making ethanol by fermentation. Manufacturing alcohols from alkenes Ethanol is manufactured by reacting ethene with steam. cake decorating by wiltonWebVerified by Toppr. Three steps are involved in the mechanism of hydration of ethene to yield ethanol. (1) The electrophillic attack of hydronium ion protonates ethene to form carbocation.
