Alkylphenolester, composition containing it and use as synthetic lubricating oil

本发明提供了一种烯属不饱和化合物的羰基化方法，该方法为在一种催化剂体系存在下，于亚化学计量卤素阴离子和/或在共反应物不是芳族醇的情况下在酚类促进剂存在下，使烯属不饱和化合物与一氧化碳及一种共反应物反应，所述催化剂体系可由(a)一种第VIII族金属阳离子源；(b)一种膦、胂或�配位体化合物；以及(c)一种非卤素阴离子的阴离子源获得。还提供了一种可用作合成润滑剂的新型烷基酚酯。 The invention discloses a process for the carbonylation of ethylenically unsaturated compounds by reaction thereof with carbon monoxide and a coreactant in the presence of a catalyst system obtained by combining (a) a source of a Group VIII metal cation (b) a phosphine, arsine or stibine compound acting as a ligand; and (c) a source of anions, other than halide anions, carried out in the presence of substoichiometric amounts of halide anions and/or -in case of a coreactant other than an aromatic alcohol- in the presence of a phenolic promoter. The process provides novel alkylphenol esters that may find use as synthetic lubricant.
