Naphthalenedicarboxylic acid dichloride production method |
| abstract |
A naphthalenedicarboxylic acid dichloride production method includes causing a reaction between naphthalenedicarboxylic acid and a chlorinating agent at a reaction temperature of 20° C. or higher and 75° C. or lower in presence of a solvent including tetrahydrofuran. The causing a reaction in the naphthalenedicarboxylic acid dichloride production method is preferably performed in presence of N,N-disubstituted formamide. |
