Mannich reaction

A new macroporous adsorption resin immobilized tannins was prepared by immobilizing tannins on styrene-divinylbenzene copolymer using Mannich reaction,The preparation condition of amino resin and immobilizing reaction with tannins were systematically studied,and the optimum synthesis technology was obtained∶amino resin∶formaldehyde∶tannins(mass ratio) =2∶0.
