Carbonylation of olefins by copper or silver carbonyl supported catalysts at room temperature and atmospheric pressure

Copper and silver carbonyl catalysts were supported on ZrO2, ZrO2. SO3, SiO 2. Al2O3, isolite and active carbon. Carbonylation of l-hexene was carried out by using Cu(CO)(n)(+) or Ag(CO)(2)(+) supported catalyst at room temper ature and atmospheric pressure to give tert-C-7 carboxylic acid in 30 simil ar to 65% yield in batch reactor. The carbonylation of 1-octene was also ca rried out by using the same catalyst in column reactor and tert-C-9 carboxy lic acid was obtained in 17 similar to 23% yield at room temperature and at mospheric pressure.
