A composition comprising 2,3-butanediol is dehydrated to methyl vinyl carbinol and/or 1,3-butadiene by exposure to a catalyst comprising (a) M
x
O
y
wherein M is a rare earth metal, a group IIIA metal, Zr, or a combination thereof, and x and y are based upon an oxidation state of M, or (b) M
3
a
(PO

)
b
where M
3
is a group IA, a group IIA metal, a group IIIA metal, or a combination thereof, and a and b are based upon the oxidation state of M
3
. Embodiments of the catalyst comprising M
x
O
y
may further include M
2
, wherein M
2
is a rare earth metal, a group IIA metal, Zr, Al, or a combination thereof. In some embodiments, 2,3-butanediol is dehydrated to methyl vinyl carbinol and/or 1,3-butadiene by a catalyst comprising M

O
y
, and the methyl vinyl carbinol is subsequently dehydrated to 1,3-butadiene by exposure to a solid acid catalyst.
一种包括2,3-丁二醇的组合物通过暴露于催化剂而被脱水成为甲基乙烯醇和/或1,3-丁二烯,所述催化剂包括(a) MxOy,其中M是稀土金属、III A族金属、锆或二者的组合物,x和y基于M的氧化态,或(b) M3a(PO4)b,其中M3是IA族金属、IIA族金属、III A族金属或二者的组合物,a和b基于M3的氧化态。包括MxOy的催化剂的实施例可能进一步包括M2,其中M2是稀土金属、IIA族金属、锆、铝或二者的组合物。在一些实施例中,2,3-丁二醇通过包括MxOy的催化剂被脱水成为甲基乙烯醇和/或1,3-丁二烯,然后通过暴露于固体酸催化剂将甲基乙烯醇进一步脱水成为1,3-丁二烯。
