| titleOfInvention | Method for isolating epsilon-caprolactam material |
| abstract | Epsilon -CAPROLACTAM MATERIAL SUCH AS A MONOMER, OLIGOMERS AND POLYMERS OF Epsilon -CAPROLACTAM AND MIXTURES OF THESE COMPOUNDS ARE PURIFIED FROM IMPURITY COMPOUNDS SUCH AS PHOSPHORIC ACID AND IONIZED METAL COMPOUNDS CONTAINED THEREIN BY BRINGING THE Epsilon -CAPROLACTAM MATERIAL INTO CONTACT WITH AN AQUEOUS SOLUTION CONTAINING 15 TO 75 PERCENT BY WEIGHT OF AT LEAST ONE ALKALI METAL PHOSPHATE TO EXTRACT THE IMPURITY COMPOUND FROM THE Epsilon -CAPROLACTAM MATERIAL INTO THE PHOSPHATE AQUEOUS SOLUTION AND, THEREAFTER, SEPARATING THE Epsilon -CAPROLACTAM MATERIAL FROM THE PHOSPHATE AQUEOUS SOLUTION BY WAY OF SETTLING OR CENTRIFUGING THE MIXTURE. |
