Claims
- 1. In a catalyst useful in dealkoxyhydroxymethylation of acetals and which contains a metal selected from the group consisting of cobalt and both ruthenium and cobalt, the improvement wherein said catalyst additionally contains a promoter of the formula ##STR7## or mixtures thereof, wherein R' and R", each of which may be the same or different, are hydrogen, alkyl, cycloalkyl, or aryl; and wherein the R' groups, when other than hydrogen, may, when taken together, form a cyclic compound.
- 2. Catalyst according to claim 1 wherein said metal is cobalt.
- 3. Catalyst according to claim 2 wherein said cobalt is cobalt carbonyl.
- 4. Catalyst according to claim 1 wherein said metal is both cobalt and ruthenium.
- 5. Catalyst according to claim 4 wherein said cobalt and ruthenium are cobalt carbonyl and ruthenium carbonyl.
- 6. Catalyst according to any one of claims 1-5 wherein the promoter is PhP(OEt).sub.2, PhP(OCH.sub.3).sub.2, Ph.sub.2 P(OEt), Ph.sub.2 P(OCH.sub.3), PhP(OCH.sub.2).sub.2, PhP(OBu), or C.sub.5 F.sub.5 P(OEt).sub.2, wherein Ph is phenyl, Et is ethyl, and Bu is butyl.
