| titleOfInvention | A kind of preparation method of phosphite and phosphite reaction kettle |
| abstract | The invention discloses a phosphite preparation method and a phosphite reaction kettle. S1. adding water and aliphatic alcohol to the reaction kettle to obtain a mixture, and slowly heating the mixture to 30-60 DEG C. S2. taking phenol, Triethylamine and toluene are mixed and stirred to obtain a mixed solution, and the mixed solution is cooled to -5～-2°C, S3. Add the toluene solution of diphenylphosphorus chloride during stirring as described in S2, S4. The mixed solution obtained in S2 is heated, mixed with the mixture when heated to 50°C, and then heated to 75°C, S5. The mixture obtained in S4 is heated and incubated at 75°C, and the holding time is 2-3 hours, S6. Cool and add caustic alkali after 2-3 hours, and filter, S7. Wash the filtered precipitate. Through the above structure, through the mixing between phenol, triethylamine and aliphatic alcohol, the hydrolysis stability of itself is increased, the light stability is good, and the use effect is increased. |
