| 摘要 |
Reaction mixtures which are obtained on hydroformylation or carbonylation of olefinically unsaturated compounds and which contain dissolved non-volatile complex compounds of metals of group VIII of the periodic table are worked up by a method wherein the products, after distillative removal of low-boiling constituents alone, or of these constituents plus a part of the high-boiling residue, or a part of the high-boiling residue after distillative removal of the desired products, are or is extracted with carbon dioxide, a C2-C4-paraffin, a C2-C4-olefin or a normally gaseous halohydrocarbon at above the critical temperature and above the critical pressure of these (extractant) compounds. |
