A process for preparing an ether compound, the process comprising: (a) contacting an olefin with an alcohol in the presence of an etherification catalyst, under etherification conditions, to form an ether compound; (b) recovering the ether compound, unreacted alcohol and unconsumed olefin; and (c) using at least a portion of the unconsumed olefin of step (b) in an etherification process conducted according to step (a), wherein the alcohol is linear or branched alcohol alkyl containing one or two alcohol groups, and further substituted with 1, 2, or 3 activating groups independently selected from CN, NO2, F, Cl, Br, I, C1-C6 alkoxy, and -C(O)O-alkyl.
一种制备醚化合物的工艺,该工艺包括(a) 在醚化条件下,在醚化催化剂存在下,使烯烃与醇接触,形成醚化合物; (b) 回收醚化合物、未反应的醇和未消耗的烯烃;(c) 在根据步骤(a)进行的醚化工艺中使用步骤(b)中的至少一部分未消耗的烯烃,其中醇是含有一个或两个醇基的直链或支链醇烷基,并进一步被 1、2 或 3 个独立选自 CN、NO2、F、Cl、Br、I、C1-C6 烷氧基和-C(O)O-烷基的活化基团取代。
