Методът се провежда при повишена температура в газова фаза. Дехидрирането на вторичните циклични алкохоли се осъществява в присъствие на водород и накатализатор, чийто активен компонент включва в тегл.%: от 30 до 60 цинков оксид и от 40 до 70 калциев карбонат в калцитна модификация. Изобретението се отнася и до катализатор за дехидриране, до метод за получаването му и до неговото използване. The method is conducted at elevated temperatures in a gasphase. The dehydration of the secondary cyclic alcohols areeffected in the presence of hydrogen and catalyst the activecomponent of which includes, in wt.%: from 30 to 60 zinc oxide andfrom 40 to 70 calcium carbonate in calcite modification. Theinvention also relates to a dehydration catalyst, to a method forits preparation and to its application.15 claims
