WebEthanol Production by catalytic hydration of ethylene — 2/21 1. Introduction This project was devoted to the study of ethanol pro-duction by catalytic hydration of ethylene. A process for the ethanol synthesis has been developed and the operating conditions optimized in order to reduce pro-duction costs. Before the extended literature review, a WebThe net addition of water to alkenes is known as hydration. The result involves breaking the pi bond in the alkene and an OH bond in water and the formation of a C-H bond and a C-OH bond. The reaction is typically exothermic by 10 - 15 kcal/mol, 1 but has an entropy change of -35 - -40 cal/mol K.
