| Introduction | tetrabutyl titanate easily reacts with Amino, hydroxyl, carboxyl, amide and other polar groups, in particular, it is highly susceptible to hydrolysis reactions with water. Dissolved in a variety of organic solvents in addition to ketones. |
| Application | tetra-n-butyl titanate is an organic titanium compound, which is used as a catalyst for polycondensation reaction and cross-linking reaction, mainly used for esterification and Ester exchange reaction, such as the synthesis of polyester polyols. It can also be used for metal-plastic tackifier, high strength polyester paint modifier, crosslinking agent and so on. |
| Use | for transesterification reaction, can be used as high strength polyester paint modifier, high temperature resistant coating additives, medical adhesives, cross-linking agent and condensation reaction catalyst, etc. used in transesterification reaction, applied to coating can improve the thermal resistance (heat resistance to 500 ℃), improve the adhesion of coating, rubber and plastic to metal surface, also used as condensation catalyst, cross-linking agent. exchange reaction. Enhance the heat resistance of the coating (heat up to 500 °c). Improved adhesion of paints, rubbers and plastics to metal surfaces. Condensation catalyst. Cross-linking agent. transesterification reaction. Enhance the heat resistance of the coating (heat up to 500 °c). Condensation catalyst. Cross-linking agent. for ester exchange reaction |
| production method | results from the reaction of titanium tetrachloride with butanol. 153kg of dry industrial benzene shall be cooled to below 20 °c, and 22.8kg of titanium tetrachloride shall be added with stirring at a temperature not exceeding 45-50 °c. After addition, ammonia gas was introduced when the temperature dropped below 15 ℃. At 20 °c and pH 9-10, 32.5kg of butanol was slowly added and ammonia was continued for about 1H until the pH was maintained at 9-10. Stirring was continued for 2H, left and filtered, and the filter cake was washed with a small amount of benzene. Benzene was recovered from the filtrate and filtered to obtain about 22-25kg crude product. The fraction was fractionated under reduced pressure, and a fraction of 195 ° C. (1.33kPa), I .e., a finished tetrabutyl titanate, was collected. Feed consumption (kg/t) toluene (98%) 1000 titanium tetrachloride (99%) 1000 n-butanol (99%) 1400 liquid ammonia (industrial) 1000 |
