一般描述

四异丙醇钛(IV)是一种钛基配位化合物，通常用于烯丙醇的夏普莱斯不对称环氧化反应(asymmetric Sharpless epoxidation reaction)。这种成分还可用作合成环丙烷的Kulinkovich反应的催化剂。

应用

常作为前体用于制备二氧化钛 (TiO2)
通过两步溶胶-凝胶法从钛酸异丙酯形成的新型金属氧化物/膦酸盐杂化物。 钛酸锶钡薄膜起始物质。用于合成介孔钛硅材料，后者是一种可能用于放射废物清洁的离子交换材料。 参与合成TiO2纳米晶体紫精电子受体复合体构成的异超分子，后者的光诱导电子转移特性已经过研究。

包装

推荐将25 mL的Sure/Seal™瓶作为一次性使用。 重复的刺穿可能会导致产品性能的下降。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What needs to be done if Product 205273, Titanium (IV) Isopropoxide is a solid instead of a liquid?

    The material will melt/freeze at 18-20 deg C, therefore the material can freeze when shipped during the winter months.  It can be warmed in a water bath to about 30 deg C to change the state without harming the chemical.

  4. What is Product 205273, Titanium (IV) Isopropoxide soluble in?

    This chemical is very soluble in ethanol, carbon tetrachloride, hexane, benzene, or isopropanol.  Water is not recommended as a solvent because titanium (IV) isopropoxide will hydrolyze. (Precautions should be taken to make sure the solvents used do not contain any water - anhydrous grades would be recommended).

  5. What is the viscosity of Product 205273, Titanium (IV) Isopropoxide?

    The viscosity of titanium (IV) isopropoxide is 4.5 centipoise at 25 deg C.

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
