| Use | Used as a gas chromatography fixative, cellulose and plastic plasticizer and camphor incombustible substitute in celluloid Used to increase the plasticity and flow performance of plastic processing and molding Used as plasticizer for nitrocellulose, acetate fiber and polyvinyl chloride and other plastics Triphenyl phosphate tpp is mainly used for flame retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber, it can also be used for flame retardant plasticization of engineering plastics such as triacetate thin ester and film, rigid polyurethane foam, phenolic resin, and PPO. gas chromatography stationary solution (the maximum service temperature is 175 ℃, the solvent is ether), the selectivity is similar to polyethylene glycol, and can selectively retain alcohol compounds. |
| production method | methods include: direct method of (I) phosphorus oxychloride (thermal method) and indirect method of phosphorus trichloride (cold method). (1) Heat method????? Dissolve phenol in pyridine and anhydrous benzene solvent, slowly add phosphorus oxychloride below 10 ℃, then react for 3-4 hours under reflux humidity, and after cooling to room temperature, the reactant is washed with water to recover pyridine, used for dehydration of sodium sulfate, filtration to remove sodium sulfate, and distillation to recover benzene under normal pressure. Decompression distillation collects the fraction of 243-245 ℃/1.47KPa, and is cooled, crystallized and crushed to obtain the finished product. (2) Cold method?????? Dissolve phenol in pyridine and anhydrous benzene solvent, then add phosphorus trichloride dropwise at 40 ℃ to generate triphenyl phosphite, continue to pass chlorine at 70 ℃ to generate trichlorophosphate triphenyl acid, and then hydrolyze at 80 ℃ to generate triphenyl phosphate. The hydrolysate is washed with water, neutralized with alkali, concentrated and then distilled under reduced pressure to obtain the finished product. Refining method: It often contains impurities such as phenol, phosphoric acid and acidic phenyl phosphate. Recrystallization refining with ethanol or a mixture of ethanol and solvent gasoline. |
