Abstract
A process is disclosed for preparing tertiary olefins having a high degree of purity and in good yields starting from tertiary ethers such as methyltert.butyl ether and in which the improvement comprises using an extremely efficient catalyst system which consists of a crystalline silica having a high specific surface area and which has been modified by an oxide of a metallic cation having an at least partially amphoteric character. Such catalyst may be, if appropriate, accompanied by an alumina-modified silica as an adjuvant co-catalyst.
