Title:
ジエンの製造方法
Document Type and Number:
Japanese Patent JP7033127
Kind Code:
B2
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. 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.
