Method for purifying dimethyl 4,4'-biphenyldicarboxylate |
| abstract |
(57) [Summary] [Purpose] To avoid production restrictions due to distillation at high temperatures and prevent decomposition reactions such as decarboxylation, and to improve production efficiency D It is a main object to provide a method capable of purifying M-BDC. Constitution: Crude crystals of dimethyl 4,4'-biphenyldicarboxylate are dissolved in a solvent consisting of at least one specific high boiling point compound, insolubles are removed by filtration, and then crystallized. |
