TYZORTPT

The diisopropoxy-bis-(triethanolamine)-titanate, TYZORTE [36673-16-2] is an excellent cross-linker for aqueous solutions of hydroxyl-containing polymers. The reaction product of TYZORTPT with a mixture of trialkano1 amines and dialkanolarnines or monoalkano1 amines can be used to cure polyester-based powder coatings (109). Other ligands of this type iaclude triisopropano1 amine [122-20-3] ... 

The ratio of yy -epoxide (shown above) to ant -eipoxide is 10—25 1 with TYZORTPT catalysis, whereas vanadjdacetylacetonate is less selective and y -chloroperoxybenzoic acid gives the reverse 1 25 ratio. It is supposed that TYZOR TPT esterifies the free hydroxyl, then coordinates with the peroxide to favor yy -epoxidation (135). This procedure is related to that for enantioselective epoxidation of other allyflc alcohols in 9—95% enantiomeric excess (135). 

Reaction of 2,4-diorgano-l,3-diols, such as 2-ethylhexane-l,3-diol, with TYZORTPT in a 2 1 molar ratio gives the solvent soluble titanate complex, TYZOR OGT [5575-43-9] (4) (73). If the reaction is conducted in an inert solvent, such as hexane, and the resultant slurry is treated with an excess of water, an oligomeric hydrolysis product, also solvent-soluble, is obtained (74).
