Around 1000 kelvin, this reaction would occur: 2 H X 2 S O X 4 ↽ − − ⇀ 2 S O X 2 + 2 H X 2 O + O X 2. This is industrially used for the production of hydrogen gas, and the total reaction cycle is called the sulphur-iodine cycle. Share. WebThe facts. Ethanol 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 overall products are an alkene and water. Only certain alcohols can react in elimination reactions. Alcohol elimination reactions take place via either an E1 or E2 mechanism.
WebAlkyl halides undergo elimination via two common mechanisms, known as E2 and E1, which show some similarities to S N 2 and S N 1, respectively. In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as C β-X bond cleavage). In E1, elimination goes via a first order rate law, …
