Preferably, said alkenol having a number of carbon atoms greater than or equal to 4 may be obtained directly through biosynthetic processes, or through catalytic dehydration processes of at least one diol. When said alkenol is a butenol, said diol is preferably a butanediol, more preferably 1,3-butanediol, even more preferably bio-1,3-butanediol, i.e. 1,3- butanediol deriving from biosynthetic processes. When said alkenol is 1,3-butanediol, or bio-1,3-butanediol, the diene obtained with the process according to the present invention is, respectively, 1,3-butadiene, or bio-1,3-butadiene.
