WebDec 14, 2024 · fruits. (Source: UC Davis). Ethylene is a gaseous plant hormone that plays an important role in inducing the ripening process for many fruits, together with other hormones and signals. An unripe fruit generally has low levels of ethylene. As the fruit matures, ethylene is produced as a signal to induce fruit ripening. WebThis is a similar process to that used to make hydrocarbons used in gasoline, the MTG (Methanol to Gasoline) process. (iii) The reaction between ethene and butenes. Another promising method is one from ethene and butene: Bio-based ethene can be obtained by dehydration of bioethanol using a silica/alumina or alumina catalyst.

Ethylene is dimerized by hydrovinylation to give n -butenes using processes licensed by Lummus or IFP. The Lummus process produces mixed n -butenes (primarily 2-butenes) while the IFP process produces 1-butene. 1-Butene is used as a comonomer in the production of certain kinds of polyethylene.
