Abstract: A polymerisation catalyst comprising:
(A) rare earth metal component selected from the group consisting of (1) a reaction mixture obtainable by treating a silica support, a carbon black support or a mixed support thereof with a mono- or di-ethyl aluminium chloride, adding a neodymium carboxylate in the presence of a solvent to form a slurry, and removing the solvent or (2) a reaction mixture obtainable by dissolving a neodymium carboxylate in a first solvent, adding silica or carbon black, and removing the solvent to obtain a dry solid, contacting the dry solid with a solution containing a mono- or di-ethyl aluminium chloride in a second solvent, and removing the second solvent; and (B) a co-catalyst selected from the group consisting of a diisobutyl aluminium hydride, triisobutyl aluminium, and a mixture thereof.Abstract translation: 1.一种聚合催化剂,其包含:(A)选自以下的稀土金属组分:(1)通过将二氧化硅载体,炭黑载体或其混合载体与单或二乙基氯化铝处理而获得的反应混合物 ,在溶剂存在下加入羧酸钕形成浆料,除去溶剂或(2)通过将羧酸钕溶解在第一溶剂中获得的反应混合物,加入二氧化硅或炭黑,除去溶剂,得到 干燥的固体,将干燥的固体与含有氯化一乙基铝或二乙基乙基铵的溶液在第二溶剂中接触,并除去第二溶剂; 和(B)选自氢化二异丁基铝,三异丁基铝及其混合物的助催化剂。

Abstract: Disclosed is a novel catalyst for the carbonylation of one or more of alcohols, ethers and ether alcohols to esters and, optionally, to carboxylic acids. The reaction is effected in the vapor state over a solid catalyst comprising a polyoxometalate anion in which the metal is at least one taken from Group V and VI of the Periodic Chart of the Elements complexed with a cation from a member of Group VIIIA of the Periodic Chart of the Elements. Preferably, the catalyst is deposited on a support that is inert to the reaction. The preferred support is silica.
