TITANIUM CATALYST SOLUTION FOR PRODUCING POLYESTER

摘要

PROBLEM TO BE SOLVED: To provide a technique for preventing deposits from being caused when storing an ethylene glycol solution of a titanium compound as a catalyst solution for a long period. SOLUTION: The catalyst solution is obtained by adding an organic acid in an amount within a range of 1-10 molar times as much as the amount of the titanium element in the solution to an ethylene glycol solution containing 0.1-20 wt.% tetraalkoxytitanium.
