Abstract: The present invention relates to a process for producing a diene, preferably a conjugated diene, more preferably 1,3-butadiene, comprising the dehydration of at least one alkenol having a number of carbon atoms greater than or equal to 4, in the presence of a catalytic material comprising at least one crystalline metalosilicate in acid form, preferably a macroporous zeolite, more preferably a zeolite with a FAU, BEA or MTW structure. Preferably, said alkenol having a number of carbon atoms greater than or equal to 4 may be obbtained 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.
