Title:ALDEHYDES BY OLEFIN HYDROFORMYLATION
Disclosure 115-DIV U.S. Patent 5,082,997
Olefins are reacted with carbon monoxide and hydrogen to produce aldehydes to the near exclusion of alcohols in the presence of a solid phase catalyst, consisting essentially of one or more sulfided Group VIII metals (preferably nickel, cobalt, iron, and rhodium).
This invention produces aldehydes via a process that is not vulnerable to poisoning by sulfur-containing species in the feedstock.In addition, the process obviates costly separation processes currently required to recover the conventional homogeneous catalysts.
