Application

Titanium(IV) ethoxide can be used:
  • As an activator and dehydrating agent for by condensation of (S)-(+)-p-toluenesulfinamide with aldehydes and ketones to form sulfinimines.
  • As a Ti4+ ion source to form complexes of titanium (IV) acrylate with methacrylic acid.
  • As a catalyst to synthesize esters of sterically hindered alcohols via transesterification reactions.

Caution

During storage a gelatinous residue may form, which dissolves after heating up to 40 °C
