Title:
PROCESS FOR SYNTHESIS OF 10,10'-DIBROMO-9,9'-DIANTHRACENE
Document Type and Number:
WIPO Patent Application WO/2010/133129
Kind Code:
A1
Abstract:
Disclosed is a process for the synthesis of 10,10'-dibromo-9,9'-dianthracene, which pertains to the technical field of the synthesis of organic electroluminescent materials, wherein 9,9'-dianthracene is used as the raw material, chlorinated hydrocarbon is used as the solvent and bromine is used as the bromination reagent. The process doesn't raise environment pollution, the yield is very high, and the reaction time is short, thus the process is suitable for industrial production.
