SYNTHESIS AND PROPERTIES OF PPAECH FROM PIPERAZINE AND EPICHLOROKYDRIN

On different experimental condition,cation polymer PPAECH has been synthesized from piperazine and epichlorokydrin. The conditions of synthesizing PPAECH are optimized according to the viscosity and yield of the copolymers. PPAECH can be used as flocculating agent in oil-exploitation sewerage of oil field, and flocculating property of PPAECH has been studied. The results show that the optimum condition is that the temperature of the reaction is 50℃, the time of the reaction is 3.5 h, and adscititious water is 0. PPAECH has better flocculating property,the best add quantity is 5 mg/L. The mixture of PPAECH and PAC is stable, and has preferable properties.
