| titleOfInvention | Method of obtaining polyketone |
| abstract | This invention relates to the production of polyketones by catalytic copolymerization of carbon monoxide and ethylene. The invention improves the speed of the process of copolymerization of carbon monoxide and ethylene and increases the yield of the target product to 2535 g / g of palladium due to the fact that the solvent used is a monocarboxylic acid selected from the group including formic, acetic, propionic, oily or isomalous; as a palladium compound, selected from the group of divalent palladium compounds, including dicarboxylate, bisfi-diketonate), 6nc- (N-alkylsalicylate iminate), sulfate, nitrate, diperchlorate, and bis- (het-fluorborate), and additionally, a sulfonic acid selected from the group including benzenesulfonic acid, p-toluenesulfonic acid, fluoromethanesulfonic acid, propanesulfonic acid and perfluorooctanesulfonic acid is introduced at a sulfonic acid concentration of 0.01-0.5 mol / l of the reaction mixture, and the process is carried out at a molar ratio of compound p Alladi: Organic Fosfonsulfonate 1: (1-50) :( 10-1000). The process is preferably carried out at 70-120 ° C and the molar ratio of carbon monoxide to ethylene is 1: (0.25-4). 2 hp f-ly, 2 tab. from 8 (L |
