Reaction Conditions:

with diethylamine in hexane at 0; for 1 h;Inert atmosphere;Reagent/catalyst;

Steps:

1.1-1.4; 2.1-2.4; 3.1-3.4; 4.1-4.4; 5.1-5.4; 1.1-1.4 This embodiment is a method for preparing titanium tetraisopropoxide, and the steps are as follows

Under the protection of nitrogen, stir TiCl4 (151.2g, 0.8mol) and isopropanol (192g, 3.2mol) in n-hexane (1L) and place them in a low temperature cold bath at 0;(2) Diethylamine (351g, 4.8mol) was added dropwise to the reaction system of step (1), which took 30min, that is, the addition rate of the diethylamine was 9.6mol/h;(3) After the reaction system of step (2) continues to react for 1 hour, under the protection of nitrogen, filter with suction,The filtrate was obtained, and the solvent was distilled off under reduced pressure at 30°C to obtain 216 g of crude product with a yield of 95%;(4) Distill and purify the filtrate under the condition of a vacuum of 0.1 Torr,Collect the fraction from 62 to 65°C to obtain titanium tetraisopropoxide product (193g, 0.68mol),The yield is 85%, it is a colorless and transparent liquid. ICP shows that the metal purity is 99.99%.The chemical purity is 99%
