Abstract From the Canadian patent

This invention is a process for converting hydrocarbonaceous feeds, particularly lower alkanes, into their corresponding esters and optionally into various intermediates (such as alcohols) and optionally into liquid hydrocarbons. The hydrocarbonaceous feeds are oxidatively converted to oxy-esters at high selectivity and conversion and at practical reaction rates using at least catalytic amounts of certain class "B" metals and/or metal ions defined by the Pearson definition as "soft" or "borderline". Desirable catalysts comprise such metals as Pd, Tl Pt, Hg, and Au. Mercury is, most desired. If so desired the oxy-esters may be converted to, alcohols or other intermediates such as halides. …

Why it's free to use

  • Filed February 14, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 14, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 14, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
