Title:
PROCESS FOR SYNTHESIS OF 9,9'-DIANTHRACENE
Document Type and Number:
WIPO Patent Application WO/2010/133128
Kind Code:
A1
Abstract:
Disclosed is a process for the synthesis of 9,9'-dianthracene, which pertains to the technical field of the synthesis of organic electroluminescent materials. In the process for synthesizing 9,9'-dianthracene, hydrochloric acid is added in batches to the glacial acetic acid solution, which has dissolved anthraquinone (raw material) and zinc (reducing reagent). The reaction temperature is maintained at 70-120℃ to obtain the end product. The one-step process has lower cost and fewer side-product formed, and needs no special purification. The process can also be used to synthesize relevant analogs and is suitable for large-scale industrial production.
