Several catalysts having activity for the catalytic conversion of methanol into DME are known as the so called acidic dehvdration catalysts.It is generally accepted that acid catalysts are the best materials for the dehydration of methanol to dimethyl ether and that Bronsted or Lewis acids are capable of performing this reaction.As examples of known acidic dehydration catalysts alumina,e.g. 一alumina,silica,alumina—silica mixtures,crystalline aluminosilicates,crystalline zeo-lites,clays,and phosphates such as alumi nium phosphates may be mentioned

具有能将甲醇催化转化成DME(二甲醚)的活性的几种催化剂被称为所谓的酸性脱水催化剂.人们一般都认可酸催化剂是甲醇脱水成二甲醚的最佳材料,并且认可布朗斯台德酸或路易斯酸能够进行这种反应.作为已知的酸性脱水催化剂的例子,例如一氧化铝、二氧化硅、氧化铝 - 二氧化硅的混合物、结晶硅铝酸盐、结晶沸石吸住、粘土,和磷酸盐(如磷酸铝)斗可以被提及.
