How we can remove a titanium catalyst after esterification reaction? Adding water gave a white gel of titanium hydroxide which is very difficult to remove. Is there any way to remove this ppt? Or any other way to remove titanium?

Neutralization via addition of sodiumhydroxide solution followed by separation of aqueous and organic layer is the procedure. But as the NaOH solution is added whole the mass turn to thick ppt which is not separable to aqueous and organic layers. Any clue to solve this problem?
