Abstract:
     Mother liquor is prepared by mixing adipic dinitrile waste, phosphoric acid (as promoter) and water in proper proportion. This mother liquor is again mixed with an anti-foulant, such as phosphate of polyols. Waste of adipic acid production organic phosphates or polycarboxy-acid type antifaulant, individually to be various water stabilizers. These water stabilizers are effective at room-temperature to 90 deg.C. and suitable for water of any PH-value and high concentration ratio(1.5-4). Their dispersing ability is good, anti-fouling effect is excellent.
