NOVEL TITANIUM CATALYST END PROCESS FOR THE PREPARATION THEREOF

摘要

The invention relates to a process for the preparation of titanium glycolate comprising the steps of reacting a titanium alkoxide with ethylene glycol in a molar ratio of the titanium alkoxide to ethylene glycol from 1:2 to 1:4 in a protic solvent at a temperature in the range from 50 to 100° C. to form titanium glycolate. The invention also relates to the titanium glycolate obtainable by said process and to use of said titanium glycolate in a catalyst composition in the preparation of a polyester or in a transesterification process.
