Title:
CRYSTAL OF 2,2'-BIS(CARBOXYMETHOXY)-1,1'-BINAPHTHYL
Document Type and Number:
WIPO Patent Application WO/2019/230685
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel crystal of 2,2'-bis(carboxymethoxy)-1,1'-binaphthyl suitable as a resin raw material having excellent optical characteristics. As a solution, it was found that by carrying out crystallization using a particular solvent, a crystal of 2,2'-bis(carboxymethoxy)-1,1'-binaphthyl is obtained that is represented by a chemical formula, that has an endothermic peak top temperature, as measured by differential scanning calorimetry, falling within a specific range, and that has an aerated bulk density falling within a specific range.
