| titleOfInvention | A kind of preparation method of tricresyl phosphate-diphenyl ester |
| abstract | The present invention relates to a kind of preparation methods of tricresyl phosphate-diphenyl ester, method includes the following steps: 1) esterification: then phenol is added dropwise in phosphorus oxychloride and catalyst mixing thereto, after reaction, vacuum distillation obtains diphenyl phosphoryl chlorine；2) it Depressor response: is reacted under intermediate diphenyl phosphoryl chlorine and M-and P-cresols that step 1) obtains are depressurized, removes the hydrogen chloride gas of reaction, obtain tricresyl phosphate-diphenyl ester crude product；3) refine: crude product tricresyl phosphate-diphenyl ester alkali cleaning, the washing that step 2) is obtained, vacuum distillation obtain tricresyl phosphate-diphenyl ester.Using phosphorus oxychloride and phenol reactant, diphenyl phosphoryl chloromethylated intermediate is prepared, the intermediate of generation reacts the synthetic route for preparing product with M-and P-cresols, reduces phosphoric acid xylyl phenyl ester, tricresyl phosphate, triphenyl phosphate impurity, to improve purity. |
