Abstract
The disclosure concerns a method for preparing acrolein from glycerol, according to which a dehydration of the glycerol is carried out in the presence of a catalyst MWOA, wherein MWO represents a mixture of simple oxides and/or mixed oxides of tungsten and at least one metal M selected among zirconium, silicon, titanium, aluminium and yttrium, and A represents one or several Lewis base(s), one said Lewis base being of the formula B(R1)p(R2)q(R3)r, wherein B is an element selected among C, S, P, O, N and halides, R1, R2 and R3 represent, independently of each other, H, a C1-C6 alkyl group, O, OH or OR wherein R represents a C1-C6 alkyl group, and the sum of p, q and r varies from 0 to 4.
