The invention relates to novel zinc/metal hexacyanocobaltate complex compounds corresponding to the formula:, Zn3-v M vCo(CN)62~ W(H20)~ x(L) ~ yZn(X)n~ zM(Y)m) These complex compounds are suitable catalysts. This invention also relates to aprocess for the production of the compounds and to the use of the compounds in, a process for the production of polyether polyols. These novel zinc/metal hexacyanocobaltate complex compounds when used as catalysts in a process for the production of polyether polyols substantially reduce the induction period of the polyaddition reaction of alkylene oxides to starter compounds containing hydrogen atoms. Furthermore the resultant polyether polyols, have a …

Why it's free to use
- Filed July 13, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 13, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 13, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
