A catalyst composition is disclosed. The composition comprises a titanium compound, a complexing agent, a solvent, and optionally a cocatalyst. The cocatalyst can be a cobalt/aluminum catalyst, an antimony compound, or combinations thereof. Also disclosed is a process for producing the composition. The process comprises combining a titanium compound, a complexing agent, a solvent, and optionally a cocatalyst. Further disclosed is a process for using the composition which comprises contacting a carbonyl compound, in the presence of the composition, with an alcohol under a condition suitable for esterification, transesterification, polymerization, or combinations thereof.
A composition comprising an organic titanium compound, a complexing agent, a phosphorus source, and a solvent wherein said complexing agent is selected from the group consisting of hydroxycarboxylic acids, aminocarboxylic acids, and combinations thereof;
A composition prepared by combining a titanium compound, a complexing agent, a phosphorus source, and a solvent wherein said complexing agent is selected from the group consisting of hydroxycarboxylic acids, aminocarboxylic acids, and combinations thereof;
A process comprising combining a titanium compound, a complexing agent, a phosphorus source, and a solvent wherein said complexing agent is selected from the group consisting of hydroxycarboxylic acids, aminocarboxylic acids, and combinations thereof;
A process comprising contacting, in the presence of a catalyst, a carbonyl compound and an alcohol wherein said catalyst comprises a titanium compound, a complexing agent, a phosphorus source, and a solvent wherein said said complexing agent is selected from the group consisting of hydroxycarboxylic acids, aminocarboxylic acids, and combinations thereof;
