With the help of the high gravity co-precipitation,with copper nitrate and zirconium oxychloride solution,using 20% sodium hydroxide as the precipitant,the Cu/ZrO2 catalyst was prepared,which was used for the synthesis of iminodiacetic acid from diethanolamine via dehydrogenation.The optimal conditions were obtained by orthogonal experiments: high gravity reactor speed of 800 r/min,precipitation end-point pH of 12,aging time of 5 h,zirconium/copper atomic molar ratio of 2∶1 and the initial… CONTINUE READING
