/ - PALLADIUM CATALYST SYSTEM COMPRISING ZWITTERION AND/OR ACID-FUNCTIONALIZED IONIC LIQUID

摘要

The present invention, specifically, palladium (Pd), zwitterions, and / or acid on the catalyst system relates to a catalyst system comprising a functionalized ionic liquid and at least one phosphine ligand, wherein the Pd catalyst _{Pd (CH 3 COO) 2,} PdCl 2, Pd (CH 3 COCHCOCH 3), Pd (CF 3 COO) 2, Pd (PPh 3) 4 or Pd ₂ (dibenzylideneacetone) by the complex precursor, such as ₃ It can be provided. Such catalyst systems are, for example, in the production of methyl propionate and / or propanoyl acid, optionally in the step to form methyl methacrylate and / or methacrylic acid, such as alkoxy carbonylation reaction, carboxylated reaction and / or it may be used in the copolymer reaction. The catalyst system according to the present invention is suitable for the reaction and the supported ionic liquid SILP purpose of forming a separable product and a catalyst phase.
