Processes for preparing calixarenes |
| abstract |
This invention relates to a process for preparing a calixarene compound by reacting a phenolic compound and an aldehyde in the presence of at least one nitrogen-containing base as a catalyst to form the calixarene compound. The invention also relates to processes for high-yield, high solid-content production of a calixarene compound, with high selectivity toward a high-purity calix[8]arene compound, without carrying out a recrystallization step. |
