摘　　要：玉米淀粉在碱、氧气和催化剂作用下可氧化水解得到一种含有多羧基的聚合物。该聚合物由于具有羧基,对钙、镁等金属离子具有一定的络合能力。且由于分子中有分子量相对较大的部分,对污垢有一定的分散作用,因此可作为洗涤助剂应用于合成洗涤剂中。针对于此,本文考查了催化剂用量、浴比、通氧量、反应时间对玉米淀粉水解氧化物性能的影响。研究结果表明,玉米淀粉水解氧化物的生产工艺简单,具有一定的络合钙离子能力,可作为洗涤助剂用于配制无磷洗衣粉。Corn starch can be oxidated and hydrolyzed to polymer which contains multi-carboxyl in the presence of the alkali、oxygen and catalyst.The polymer has definite coordinating ability to some metallic ions (Ca^(2+), Mg^(2+) etc) on account of containing carboxyl,and it has definite dispersion ability to dirt owing to relative large molecular weight.It can be used in the synthesis of detergent as detergent builder.Effect of catalyst concentration、bath ratio、oxygen quantity inputted and reaction time on the performance of hydrolytic oxide of corn starch are investigated.Experiment results show that this production technology is simple and has definite coordinating ability to Ca^(2+),so it can be used as detergent in preparation of phosphate-free washing powder.
