PROCESS FOR THE PURIFICATION OF AQUEOUS ACRYLAMIDE SOLUTIONS |
| abstract |
PROCESS FOR PURIFYING AN AQUEOUS ACRYLAMIDE SOLUTION OBTAINED BY CATALYTIC HYDRATION OF ACRYLONITRILE IN THE PRESENCE OF A CATALYST CONTAINING COPPER. THE AQUEOUS ACRYLAMIDE SOLUTION IS PASSED FIRST OVER A STRONGLY BASIC ANION EXCHANGER RESIN IN THE OH FORM, THEN ON A CATION EXCHANGING RESIN IN THE H FORM. THE AQUEOUS ACRYLAMIDE SOLUTION PURIFIED ACCORDING TO THE INVENTION SUITABLE FOR DIRECT USE IN THE PREPARATION OF POLYACRYLAMIDES THEY ARE SUITABLE FOR USE AS FLOCCULANTS. |
