Title
(EN) CONVERSION OF OLEFINS TO ETHERS
(FR) CONVERSION D'OLEFINES EN ETHERS
Abstract
(EN)
Light olefins are catalytically converted to ethers, e.g., propylene is converted to diisopropyl ether, in a two stage process in which product ether is recycled to a first stage reaction zone to significantly reduce the operating temperature of the olefin hydration/etherification reactions taking place in that zone. Alcohol produced in the first stage reaction zone undergoes conversion in the second stage reaction zone, e.g., by catalytic distillation, to provide additional product ether.
(FR)
On procède à la conversion par voie catalytique d'oléfines légères en éthers, par exemple de propylène en éther di-isopropyle, par un procédé à deux phases, dans lequel l'éther produit est recyclé dans une zone de réaction de première phase, pour obtenir une réduction sensible de la température opérationnelle des réactions d'hydratation/éthérification des oléfines qui se produisent dans cette zone. L'alcool produit dans la zone de réaction de première phase subit une conversion dans la zone de réaction de seconde phase, par exemple par distillation catalytique, pour former un éther supplémentaire.
