摘要:
为进一步提高有色涤纶醇解脱色效率,利用硅烷偶联剂KH560作为界面改性剂,制备Zn(Ac)2-MgFe2O4复合催化剂,对复合催化剂的形貌、元素、热稳定性、磁性能及催化醇解脱色能力进行表征; 采用多因素实验探究有色涤纶的醇解条件。结果表明,偶联剂质量分数为1.0%时,复合催化剂的分散性能最好,且热化学性能稳定; 当MgFe2O4与Zn(Ac)2的质量比为1:3时,复合催化剂对涤纶的降解率及脱色率分别可达到98.9%和78.2%; 复合催化剂质量分数为1.0%、反应温度为196 ℃、反应时间为180 min,且乙二醇与涤纶的质量比为5:1时,涤纶的醇解脱色效果最佳; 该复合催化剂经5次回收后,仍保持较高的稳定性和回收率,对有色涤纶的降解率可达到96.0%。
Abstract:
To further enhance the efficiency of alcoholysis and decolorization of colored polyester, a composite catalyst Zn(Ac)2-MgFe2O4 was prepared using the silane coupling agent KH560 as an interfacial modifier. The morphology, elemental composition, thermal stability, magnetic properties, and catalytic capability for alcoholysis and decolorization of the composite catalyst were characterized. A multi-factor experimental approach was employed to investigate the alcoholysis conditions for colored polyester. The results indicate that the composite catalyst exhibits optimal dispersion performance and stable thermochemical properties when the mass fraction of the coupling agent is 1.0%. When the mass ratio of MgFe2O4 to Zn(Ac)2 is 1:3, the degradation rate and decolorization rate of polyester using the composite catalyst can reach 98.9% and 78.2%, respectively. The optimal alcoholysis and decolorization effects for polyester are achieved under the following conditions: composite catalyst mass fraction of 1.0%, reaction temperature of 196 ℃, reaction time of 180 min, and an ethylene glycol to polyester mass ratio of 5:1. After five cycles of recycling, the composite catalyst maintains high stability and a recovery rate, and the degradation rate for colored polyester can reach 96.0%.
