【摘要】将固体超强酸 SO42 - / Zr O2 负载稀土铈 ,制备了新型催化剂 Ce4+ - SO42 - / Zr O2 ,用于催化合成溴代正辛烷。考察了硝酸铈的质量百分浓度、焙烧温度、焙烧时间等因素对其催化性能的影响 ;并采用 IR、XRD和 Hamm ett指示剂法对其性能进行了研究。更多还原

【Abstract】 A new catalyst loaded with Ce on SO 4 2- /ZrO 2 has been prepared.It was used in the reaction for catalytic synthesis of n octyle bromide.Many factors were investigated which may affect the catalytic behavior such as mass percent concentration of Ce(NO 3) 3,roasting temperature and time and etc.Its properties were studied by IR,XRD and Hammett indicator.更多还原
