WebEthanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric (V) acid, H 3 PO 4, can be used instead. The acids aren't written into the equation because they serve as catalysts. If you like, you could write, for example, "conc H 2 SO 4 " over the top of the arrow. WebBio-ethanol can be produced by the fermentation of a variety of plant biomass, which is then converted to bio-ethylene via catalytic dehydration1. Compared to the petrochemical route, this process can save GHG emissions in the product’s entire lifecycle 2 because the plant feedstock absorbs CO2 from the atmosphere during its growth.

dehydration of ethanol to give ethene - chemguide

Web2 Ethanol Production Ethanol can be produced by catalytic hydration of ethylene, fermentation of sugars and from lignocellulosic materials. These methods (Fig.1) are discussed briefly in this section. More discussions on the technical readiness level and commer-cial plants for ethanol production can be found elsewhere [23–26]. WebEthanol is heated at 443 k in presence of excess of concentrated sulphuric acid to obtain ethene. This reaction can be given by following equation: C H 3 C H 2 O H c o n c. H 2 S O 4 C H 2 = C H 2 + H 2 O fixing trucks
