Abstract
Catalysts and proceses for the dimerization or co-dimerization of dimerizable olefins are provided. Catalysts consist essentially of at least one elemental alkali metal on one of several potassium carbonate-containing supports optionally in the presence of at least one promoter selected from the group consisting of elemental copper, elemental cobalt and finely divided stainless steel.
Claims25
A process comprising contacting at least one dimerizable olefin with a catalyst consisting essentially of:
- (a) at least one alkali metal,
- (b) elemental copper, and
- (c) potassium carbonate support;
- wherein components (a) and (b) are supported on component (c).
A process comprising contacting at least one dimerizable olefin with a catalyst consisting essentially of:
- (a) at least one alkali metal,
- (b) elemental copper,
- (c) elemental cobalt, and
- (d) potassium carbonate support;
- wherein components (a), (b) and (c) are supported on component (d).
A process comprising contacting at least one dimerizable olefin with a catalyst consisting essentially of:
- (a) at least one elemental alkali metal,
- (b) finely divided stainless steel, and
- (c) potassium carbonate support;
- wherein components (a) and (b) are support on component (c).
A process comprising contacting at least one dimerizable olefin with a catalyst consisting essentially of:
- (a) at least one elemental alkali metal,
- (b) elemental copper, and
- (c) potassium carbonate support;
- wherein (a) and (b) are supported on said potassium carbonate support and wherein said potassium carbonate support has been prepared by (i) adding sufficient water to potassium carbonate to form a thick paste, (ii) drying said thick paste, and (iii) crushing the dried paste into a particle size suitable for treatment of the potassium carbonate support with components (a) and (b).
A process comprising contacting at least one dimerizable olefin with a catalyst consisting essentially of:
- (a) at least one elemental alkali metal,
- (b) potassium carbonate, and
- (c) inorganic oxide support;
- wherein said potassium carbonate is (1) mixed with said inorganic oxide support, (2) heated to at least about 950.degree. C., (3) then cooled and treated with said at least one elemental alkali metal.
