| titleOfInvention | Method for preparing diphenyl carbonate compound |
| abstract | The invention relates to the field of diphenyl carbonate compounds, and discloses a preparation method of a diphenyl carbonate compound represented by formula (I), which comprises: formulating formula (II) in the presence of a catalyst The phenolic compound is transesterified with a carbonic acid diester compound represented by the formula (III), wherein the catalyst contains 1,4-diazabicyclo[2.2.2]octane; R is a halogen, R 1 And R 2 are each independently methyl or ethyl. The method can improve the selectivity of the diphenyl carbonate compound; the catalyst is adopted, the chemical property is stable, safe, inexpensive, and the equipment is not corroded, and the catalyst is easily separated and recovered from the reaction liquid and reused. |
