Treatment of polyamide granules with formic acid |
| abstract |
INACTIVATED POLYAMIDE GRANULES ARE REACTIVATED AND EXHIBIT IMPROVED ABSORPTIVITY BY TREATMENT WITH FORMIC ACID, SUCH AS AN AQUEOUS FORMIC ACID SOLUTION HAVING A CONCENTRATION IN A RANGE ABOUT 40-70% BY WEIGHT FORMIC ACID, AT A TEMPERATURE IN THE RANGE 0-80*C. THE FORMIC ACID TREATMENT IS USUALLY CARRIED OUT FOR A PERIOD OF FROM ABOUT ONE TO EIGHT HOURS. AFTER TREATMENT RESULTING POLYAMIDE GRANULES ARE SEPARATED SUCH AS BY FILTRATION AND RINSED WITH WATER. |
