| Use | Used for ester exchange reaction Used as an auxiliary agent and chemical product intermediate Used to make adhesives, used as a catalyst for transesterification and polymerization reactions Binders for preparing metals and rubber, metals and plastics, also used as catalysts for transesterification and polymerization reactions and raw materials for the pharmaceutical industry. Catalyst for esterification reaction, transesterification reaction of acrylic acid and other esters. As Ziegler (Ziegler Natta) catalyst in polymerization reactions such as epoxy resin, phenolic plastic, silicone resin, polybutadiene, etc., it has high stereoselectivity. In the paint, a variety of polymers or resins play a cross-linking role, improve the anti-corrosion ability of the coating, etc., and also promote the adhesion of the coating to the surface. Can be directly used as material surface modifier, adhesive promoter. polymerization catalyst. Transesterification. Can adhere paint, rubber and plastic to metal. As an additive for the Sharpless asymmetric epoxidation reaction of allyl alcohol; as a catalyst for transesterification reaction with various alcohols under neutral conditions; titanium tetraisopropoxide can be formed by a sol-gel two-step method New metal oxide/phosphonate hybrid; used as a raw material for barium strontium titanate film; used to prepare porous titanosilicate, which is a potential ion exchange material for removing radioactive waste; it is used to form heterogeneous supramolecules composed of TiO2 nanocrystals-violet essence electron acceptor complexes. It has been proved that it can undergo light-induced electron transfer It is mainly used for transesterification and condensation reactions in organic synthesis Catalyst. It is often used as a precursor to prepare titanium dioxide (TiO2). A new metal oxide/phosphonate hybrid can be formed from titanium tetraisopropoxide by sol-gel two-step method. The raw material of barium strontium titanate film. It is used to prepare porous titanosilicates, which are potential ion exchange materials for the removal of radioactive wastes. It is used to form heterogeneous supramolecules composed of TiO2 nanocrystals-violet essence electron acceptor complexes, which have been shown to be capable of light-induced electron transfer. |

titanium(4+) tetrapropan-2-olate - Nature
Open Data Verified Data
colorless to light yellow transparent liquid. Smoke in moist air. Water rapid hydrolysis, soluble in alcohol, ether, ketone, benzene and other organic solvents. In case of high heat, open flame or contact with oxidant, there is a risk of combustion. The reaction with water or water vapor gives off a toxic or flammable gas. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion.
