Abstract

Inventia se refera la un procedeu pentru descompunerea eterilor alchilter alchilici pentru a produce olefine sau alcoolul corespunzator conform caruia eterul alchil-tert-alchilic este introdus într-o coloana de distilare cu talere continînd catalizator pe baza de rasine stiren divinilbenzen olefina produsa este retrasa continuu din vîrful coloanei produsul de baza fiind constituit din alcool pur sau cel putin un amestec de alcool si eter.The invention relates to a process for the decomposition of alkyl alkyl ethers to produce olefins or the corresponding alcohol according to which the alkyl-tert-alkyl ether is introduced into a distillation column containing trays containing styrene resin divinylbenzene. The olefin produced is withdrawn continuously from the top of the column being the basic product consisting of pure alcohol or at least a mixture of alcohol and ether.
