摘要

“Processes for the preparation of an olefin, selective preparation of but-2-ene, isobutene, a mixture of olefins, a mixture of at least two olefins, propene, butadiene, acrolein and aldehyde manufacturing processes The present invention relates to a process of preparing an olefin, diene or polyene by catalytic conversion of at least one alcohol having a carbon chain of at least three carbon atoms and different from propan-2-ol. In the presence of at least one phosphate-based catalyst of one metal or several metals, m is chosen from the 15 lanthanides (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium), yttrium, scandium and boron, and the applications of this process.
