Summary:Process for producing very pure olefins of the formula by decomposition of the corresponding ethers of formula wherein R1 and R3 are selected from the group of the alkyl, arylalkyl aryl or alkylaryl radicals, R and R2 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 form 80 to 300 m2/g.
