Abstract
Catalyst comprising a combination of oxidized metals and processes for cleaving phenylalkyl hydroperoxides in the presence of the catalyst.
Claims18
A catalyst consisting essentially of:
- a combination comprising a first amount of oxidized first metal and a second amount of oxidized second metal;
- wherein the first metal is selected from the group consisting of tin, zinc, bismuth, and combinations thereof and the second metal is selected from the group consisting of zirconium, antimony, and combinations thereof.
A catalyst comprising oxidized forms of a combination of metals selected from the group consisting of:
- zirconium and tin;
- and, antimony and tin.
A process for cleaving phenylalkyl hydroperoxides comprising subjecting a feed comprising one or more phenylalkyl hydroperoxides to a catalyst composition
- comprising a catalyst consisting essentially of:
- a combination comprising a first amount of oxidized first metal and a second amount of oxidized second metal;
- wherein the first metal is selected from the group consisting of tin, zinc, bismuth, and combinations thereof and the second metal is selected from the group consisting of zirconium, antimony, tungsten, and combinations thereof
- under cleavage conditions which cleave the phenylalkyl hydroperoxides and produce a cleavage product comprising one or more hydroxybenzenes and one or more ketones.
1 more element
A process for cleaving phenylalkyl hydro-peroxides comprising:
- feeding a phenylalkyl hydroperoxide feed and a ketone feed to a reactor in a continuous process to produce a cleavage reaction mixture, the reactor containing catalyst consisting essentially of a combination of oxidized metals wherein the first metal is selected from the group consisting of tin, zinc, bismuth, and combinations thereof and the second metal is selected from the group consisting of zirconium, antimony, tungsten, and combinations thereof;
- and
- subjecting the cleavage reaction mixture to cleavage conditions in the presence of the catalyst, the cleavage conditions being effective to cleave phenylalkyl hydroperoxide and to produce a cleavage product comprising one or more hydroxybenzenes and one or more ketones.
