FormLiquid
Titanium(IV) isopropoxide is used as a precursor for the preparation of titanium and barium-strontium-titanate thin films. It is useful to make porous titanosilicates and potential ion-exchange materials for cleanup of radioactive wastes. It is an active component of sharpless epoxidation as well as involved in the synthesis of chiral epoxides. In Kulinkovich reaction, it is involved as a catalyst in the preparation of cyclopropanes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El isopropóxido de titanio (IV) se utiliza como precursor en la preparación de películas delgadas de titanio y bario-estroncio-titanato. Sirve para crear titanosilicatos porosos y potenciales materiales de intercambio iónico para la limpieza de desechos radiactivos. Es un componente activo de la epoxidación sin ácido y participa en la síntesis de epóxidos quirales. En la reacción de Kulinkovich, participa como catalizador en la preparación de ciclopropanos.

Solubilidad
Soluble en etanol anhidro, éter, benceno y cloroformo.

Nota
Sensible a la humedad. Almacénese en lugar fresco. Mantenga el recipiente bien cerrado en un lugar seco y bien ventilado. Incompatible con agentes oxidantes fuertes y ácidos fuertes. Reacciona con el agua y produce dióxido de titanio.
