| Abstract: | The na'noparticles of EuTiNiO4Cl was prepared by sol-gel method.The best condition of the product was selected by direct cross method.The na'noparticles was characterized by means of X-ray(XRD) and transmission electron microscopy(TEM) and scanning electron microscope(SEM) and atomic force microscopy(AFM).The physiognomy and sizes of na'noparticles were researched under the best condition in the different calcination temperature.The result indicated that the na'noparticles was cubical and their sizes were well-distributed.The average diameter of the EuTiNiO4Cl particles was 45nm.The etherification reaction between acetic acid and butyric alcohol was studied in the microwave eradiating,which the activator was EuTiNiO4Cl.Its catalytic in etherification activity influenced was researched which was microwave power,reaction time,the dosage of activator and the size of activator. |
