Title:
METHOD FOR PREPARING 1,4-BIS(4-PHENOXYBENZOYL)BENZENE AND 1,4-BIS(4-PHENOXYBENZOYL)BENZENE PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2022/045665
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing 1,4-bis(4-phenoxybenzoyl)benzene. According to the present invention, when a 1,4-bis(4-phenoxybenzoyl)benzene synthesis reaction is carried out at a specific temperature, the amount of heat used in the preparation process can be minimized while maintaining the same yield as that of the existing preparation method. In addition, waste solvent generated in the preparation process does not undergo a color change and thus can be reused, and thus energy saving effects can be provided.
