酚甲基化催化剂及其制备方法以及制备甲基酚的方法
摘要：
本发明提供了一种酚甲基化催化剂及其制备方法，该催化剂含有以金属元素计，摩尔比为1∶0.001-0.1∶0.001-0.1∶0.001-0.1∶0.001-0.1∶0.001-0.1的氧化铁、氧化钴、氧化铬、氧化锡、氧化铝和氧化铯，以该催化剂的总重量为基准，所述氧化铁的含量为80-99重量％。还提供了一种制备甲基酚的方法，该方法包括将酚与甲醇的混合溶液与催化剂接触，其中，所述催化剂为本发明提供的酚甲基化催化剂。本发明提供的酚甲基化催化剂不但反应活性高，稳定性好，而且使用寿命长。使用该催化剂进行酚甲基化反应转化率高，选择性好。本发明还提供的制备该催化剂的方法操作简单，制得的催化剂稳定性好。
摘要（英）：

The invention provides a phenol methylation catalyst and a preparation method thereof. The catalyst contains ferric oxide, cobaltous oxide, chromic oxide, stannic oxide, aluminum oxide and cesium oxide according to metal elements, mole ratios of which are 1:0.001-0.1:0.001-0.1:0.001-0.1:0.001-0.1:0.001-0.1; based on the total weight of the catalyst, the content of ferric oxide is 80-99 weight%. The invention also provides a method for preparing methyl phenol; the method comprises steps of: contacting mixed solution of phenol and methyl alcohol and a catalyst, wherein the catalyst is the penolmethylation catalyst provided by the invention. The phenol methylation catalyst has high reactive activity, good stability and long service life. The phenol methylation reaction using the catalyst has high conversion rate and good selectivity. The method for preparing the catalyst has simple operation and the prepared catalyst has good stability.
