Title (EN) METHOD FOR PRODUCING METHYL TERTIARY-BUTYL ETHER
(FR) PROCÉDÉ DE PRODUCTION DE MÉTHYL-TERT-BUTYLÉTHER
(KO) 메틸 3급-부틸 에테르 제조방법
Abstract:
(EN) The present invention relates to a method for producing methyl tertiary-butyl ether, the method comprising a reaction step for reacting methanol and isobutene in the presence of an acid catalyst to produce methyl tertiary-butyl ether; and introducing a reaction product obtained in the reaction step into a reaction distillation column including a packing bed containing an acid catalyst, thereby purifying the reaction product, wherein the amount of unreacted isobutene and the amount of impurities contained in a reactor are reduced by varying the flow ratio of recycle/fresh feed according to the reactor volume, and thus the amount of thermal energy used in the reaction distillation column can be reduced.
(FR) La présente invention concerne un procédé de production de méthyl-tert-butyléther, le procédé consistant à : faire réagir, dans une étape de réaction du méthanol et de l'isobutène en présence d'un catalyseur acide pour produire du méthyl-tert-butyléther; et introduire un produit de réaction obtenu dans l'étape de réaction dans une colonne de distillation de réaction comprenant un lit de garnissage qui contient un catalyseur acide, ce qui permet de purifier le produit de réaction, la quantité d'isobutène n'ayant pas réagi et la quantité d'impuretés contenues dans le réacteur étant réduites en faisant varier le rapport du courant de la charge de l'aliment recyclé/frais en fonction du volume du réacteur, et ainsi la quantité d'énergie thermique utilisée dans la colonne de distillation de réaction peut être réduite.
