Abstract
本发明披露了一种用于烷烃气相氧化成不饱和醛和羧酸的催化剂。另外还披露了该催化剂的制备方法,以及使用该催化剂使烷烃转化成不饱和醛或羧酸的使用方法。
Description
本发明涉及在制备不饱和醛和酸中使用的催化剂。本发明特别是涉及能使烷烃有效转化成不饱和醛和羧酸的催化剂以及使用所述催化剂制备不饱和醛和羧酸的方法。
不饱和醛和羧酸是重要的工业化学品。特别重要的是(甲基)丙烯酸。(甲基)丙烯酸的高活性双键和酸官能使之尤其适用作:可以单独聚合或与其它单体聚合以生产工业上重要的聚合物的单体。这些不饱和酸也用作酯化作用的原料,以便生产工业上重要的(甲基)丙烯酸酯。由(甲基)丙烯酸或(甲基)丙烯酸的酯衍生的材料可用作颜料片材和塑料部件,色漆或其它涂料,粘合剂,填缝料,密封剂和去污剂以及其它的用途。
通过烯烃氧化生产不饱和羧酸在现有技术中是熟知的。例如可以借助丙烯的气相氧化而在工业上制备丙烯酸。另外还已知的是,不饱和羧酸也可以借助烷烃的氧化来制备。由于烷烃通常比烯烃的成本更低,因此,这样的方法是特别希望的。工业上可使用的、将烷烃氧化成不饱和醛或羧酸的合适的催化剂和方法是(甲基)丙烯酸制造商们持续的目标并且必须实现。
烷烃催化氧化成不饱和醛或羧酸的工业上可使用的生产方法的一个障碍是:对于具有适当转换和合适选择性的催化剂的鉴定,借此提供不饱和羧酸或醛最终产物足够的得率。US5,380,933披露了一种烷烃气相氧化成不饱和羧酸用的催化剂的制备方法。在所披露的方法中,借助将偏钒酸铵,碲酸和对钼酸铵混合得到均匀水溶液而制备催化剂。向该溶液中添加草酸铵铌,从而得到一浆液。该该浆液中除去水并得到固体催化剂前体。将该固体催化剂前体模制成片剂,筛选成希望的粒径,然后在氮气流下于600℃进行煅烧,从而得到希望的催化剂。并断言,最终的催化剂对于将丙烷转换成丙烯酸是有效的。
共同待批美国专利申请US09/316,007披露了一种丙烷转换成丙烯酸中使用的催化剂的改进的制备方法。该方法的特征在于:使用借助各种方法进行汽提并在惰性气氛下进行煅烧的混合金属氧化物溶液。
本发明者发现了一种用于将烷烃催化氧化成不饱和醛或羧酸的新颖的催化剂。

如上所述,披露了催化剂以及催化剂的制备方法。在所述方法的第一步骤中,借助将至少一种包含氧的金属化合物,和至少一种适量的溶剂混合而形成一溶液,以便形成本发明所述的溶液。通常,金属化合物包含元素A,M,N,X,和O。在一实施方案中,A选自:Mo,W,Fe,Nb,Ta,Zr,Ru及其混合物;M选自V,Ce,Cr及其混合物;N选自:Te,Bi,Sb,Se及其混合物;而X选自:Nb,Ta,W,Ti,Al,Zr,Cr,Mn,Fe,Ru,Co,Rh,Ni,Pd,Pt,Sb,Bi,B,In,Ce及其混合物。在优选的实施方案中,A选自:Mo,W及其混合物;M选自:V,Ce,Cr及其混合物;N选自:Te,Bi,Sb及其混合物;而X选自:Nb,Ta,Zr及其混合物。在更为优选的实施方案中,A为Mo,M为V,N为Te而X为Nb。
合适的溶剂包括水,醇类,包括但不局限于甲醇,乙醇,丙醇,二醇等,以及本领域已知的其它极性溶剂。通常优选的是水。所述水是适用于化学合成的任何水,包括但不局限于蒸馏水和去离子水。所存在的水量为足以使各元素基本保持在溶液中以避免在制备步骤中的组成和/或相的分离或使之最小化所需的量。因此,水量将根据复合的材料的量和溶解性而改变。然而,正如上面所述,水量必须足以保证能形成水溶液,而不是在混合时的浆液。
一旦形成水溶液之后,立即通过本领域已知的任何合适的方法除去水份,以便形成催化剂前体。所述方法包括但不局限于:真空干燥,冷冻干燥,喷雾干燥,旋转蒸发,和空气干燥。真空干燥通常在10-500毫米汞柱的压力下进行。冷冻干燥通常需要对溶液进行冷冻,例如利用液氮,然后在真空下对冷冻的溶液进行干燥。喷雾干燥通常在惰性气氛如氮或氩气氛下进行,其中进口温度从125℃-200℃,而出口温度从75℃-150℃。旋转蒸发通常在25℃-90℃的浴温下以及10-760毫米汞柱的压力下进行,优选在40℃-90℃的浴温下以及10-350毫米汞柱的压力下进行,更优选在40℃-60℃的浴温下以及10-40毫米汞柱的压力下进行。空气干燥可以在25-90℃的温度下进行。旋转蒸发或空气干燥通常是优选的。

煅烧通常在350-850℃,优选在400-700℃,更优选在500-640℃的温度下进行。煅烧通常以适合形成催化剂的时间来进行。在一实施方案中,煅烧时间从0.5-30小时,优选从1-25小时,更优选从1-15小时。
借助煅烧,形成了具有下式的混合金属氧化物:
AaMmNnXxOo式中A,M,N,和X如上所述。摩尔比a,m,n,和x通常为0.25<a<0.98,0.003<m<0.5,0.003<n<0.5,和0.003<x<0.5;优选的是,0.35<a<0.87,0.045<m<0.37,0.020<n<0.27,和0.005<x<0.35。

在催化剂的两种制备方法中,酸均与混合金属氧化物催化剂混合。在本发明的一个实施方案中,所述酸与金属和水混合,然后如上所述除去水,以便形成混合金属氧化物催化剂前体,然后如上所述对该前体进行煅烧,以形成催化剂。
在本发明另一实施方案中,将金属和水混合并除去水,以便形成混合金属氧化物催化剂前体。然后对催化剂前体进行煅烧,以便形成催化剂。在本发明的这个实施方案中,酸然后与催化剂混合。可以借助本领域已知的方法对混合物进行搅拌,振荡,或研磨,以保证良好的混合。
所使用的酸可以选自如下的至少一种:杂多酸,氧化铝,氧化锆,氧化钛,沸石或其酸混合物。
本发明中使用的杂多酸是:带基本的、通常是中心定位原子的笼形结构,所述中心定位原子被笼形骨架所包围,所述笼形骨架包含许多相同或不同的、连接氧原子的金属原子。杂多酸的中心元素与骨架的金属原子不同,并且有时称之为“杂”元素或原子;稠合配位元素被称为“骨架”元素或金属,并且通常为过渡金属。绝大多数杂多酸具有通常通过四个氧原子以四面体的形式连接至“骨架”金属(“M”)上的中心定位杂原子(“X”)。骨架金属依次:(ⅰ)通常通过氧(“O”)以八面体的形式连接至中心原子上,(ⅱ)通过氧原子连接至另外四个骨架金属上,(ⅲ)具有称为“末端氧”原子的第六非桥接氧原子。所述结构由结构式(Ⅲ)来说明。

另外,骨架被取代的杂多酸也适用于本发明。这些化合物是:其中某些骨架原子M(和双键连接至其上的氧原子)被过渡金属取代的杂多酸。所述取代例如可以是单取代,无规-或配向-双取代,无规-或配向-三取代,或更多的取代,所有这些均将产生用作被多金属氧酸盐载体承载的杂多酸的有效组分。所述多金属氧酸盐在本领域中的已知的并且例如描述于US5,705,685和US09/002,816中。在此将所述专利中有关多金属氧酸盐的内容引入作为参考。另外,还可以借助下述的各种方法进一步促进本发明的催化剂。本发明包括:承载在未取代和取代多金属氧酸盐上的未取代和取代的杂多酸。
用于制备骨架被取代的组合物的典型的杂多酸具有如下结构式:H3PMo12O40。当三个Mo=O单元被例如铁(Fe)替代时,最终骨架被取代的杂多酸的结构式为H6PMo9Fe3O37。因此,如上所述特定选择的骨架被取代的杂多酸的通式为:
He(XkMnM1 mOy)-e式中k从1-5,n从5-19,m从1-6,y从18-62。在该结构式中,M1包含:一个或多个锌或任何过渡金属,即元素周期表第3-10族的金属。优选的过渡金属选自:第8-10族或第4-7族的第一排,例如但不局限于:铁,钴,镍,钌,铑,钯,锇,铱,铂(第8-10族)或钛,钒,铬,锰(第4-7族,第一排)。更优选的M1中,金属为铁,锰,钒和镍和铁或其它过渡金属的混合物。三个M1原子不必相同。然而,三个M1原子必须与三个替代的M不同。
用于本发明的杂多酸通常溶于水和极性有机溶剂如乙腈和醇如甲醇。这类杂多酸具有以下结构:
H(e’-bz’)Gb(Xk’Mm’-x’M1 x’M2 n’Oy’)-e’ (Ⅰ)式中G为选自1-16族的元素或其氧离子;X为选自3-16族的元素;M=钼,钨或其组合;M1=钒;M2是不同于M和M1的过渡金属;z’=G上的电荷;b=0-12;k’=1-5;m’=5-20;x’=0-6;n’=0-3;y’=18-62;e’是多金属氧酸盐阴离子的电荷。用于G的合适的元素包括但不局限于:钛,锆,铪,钒,铌,钽,铬,钼,钨,锰,铼,铁,钴,镍,钌,铑,钯,锇,铱,铂,铜,锌,或其组合。合适的用于G元素的氧阴离子包括但不局限于:钛氧基,氧钒基,铌氧基,或其组合。用于X的合适的过渡元素包括但不局限于:磷,硅,镓,铝,砷,锗,硼,钴,铈,镨,铀,钍,或其混合物。用于M2的合适的过渡元素包括但不局限于:钛,锆,铪,钒,铌,钽,铬,钼,钨,锰,铼,铁,钴,镍,钌,铑,钯,锇,铱,铂,铜,锌,或其组合。优选的是,当M为钼和钨的混合物并且该化合物为Keggin离子时,x’=0。还优选,当M为钼并且化合物为Keggin离子时,x’=0-3。另外还优选的是,当M为钨且化合物为Keggin离子时,x’=0-6。
在上面结构式中,(e’-bz’)描述了存在于催化剂的杂多酸组分中质子(“H+”)的数量。(e’-bz’)最小时优选大于或等于0.1。在本发明的一个实施方案中,(e’-bz’)大于或等于0.5,在另一实施方案中,(e’-bz’)大于或等于1。在某些实施方案中,bz’等于零,杂多酸中的质子数等于e’。在另一实施方案中,(e’-bz’)为0,因而借助用另外的酸,如硫酸对该体系进行处理而添加质子。
用于本发明的杂多酸的具体例子包括但不局限于:
H3PMo12O40,H3PW12O40,(VO)1.5PMo12O40,

用于本发明的杂多酸可从市场得到或可以通过本领域已知的各种方法来制备。用于本发明的多金属氧酸盐和杂多酸的一般合成描述于Pope等人的杂多和异多金属氧酸盐中(Springer-Verlag,NeWYork(1983))。通常,借助将希望的金属氧化物溶解于水中;用酸如盐酸将pH值调节至约1-2,以提供所需的质子;然后蒸发掉水直至得到希望的杂多酸沉淀物为止;而制备杂多酸。作为例子,杂多酸H3PMo12O40可借助将Na2HPO4和Na2MoO4进行混合;用硫酸将调节pH;用醚进行萃取;并使水中的最终杂多酸进行结晶而制备。另外,钒取代的杂多酸也可以根据V.F.Odyakov等人于Kinetics and Catalysis(1995,第36卷,第733页)中描述的方法来制备。正如在下面描述的那样,借助用碳酸铯对上述杂多酸进行处理并收集所得到的沉淀产物,可制备Cs3PMo12O40载体。
