Abstract
Process for producing very pure olefins of the formula ##STR1## by decomposition of the corresponding ethers of formula ##STR2## wherein R.sub.1 and R.sub.3 are selected from the group of the alkyl, arylalkyl aryl or alkylaryl radicals, R and R.sub.2 being a hydrogen atom or a radical selected from said above mentioned group, in the presence of steam in a molar proportion from 2 to 8 times the ether amount and with the use of a catalyst comprising alumina to which is added 0.01 to 5% by weight of titanium or zirconium or hafnium as metal or as metal compound, said catalyst having a specific surface from 80 to 300 m.sup.2 /g.
