Description
Предлагаетс епособ дегидратации бицнк.шческих терпеновых спиртов в соответствующие углеводороды с неизмененным углеродным скелетом действием сухой едкой щелочи при 170-180. Этот способ отличаетс простотой осуществлени и высоким выходом.It is proposed to use a method for dehydrating biccinic terpene alcohols to the corresponding hydrocarbons with an unchanged carbon skeleton under the action of dry caustic alkali at 170-180. This method is characterized by ease of implementation and high yield.
Известные способы дегидратации териеновых спиртов обладают тем недостатком, что при их п)оведении должны быть обеспечены чрезвычайной м гкие услови реакции. Они очень кронотлнвы в выполнении , и получаемый непредельный углеводород всегда содержит следы мерк;атггана.Known methods for the dehydration of teriene alcohols have the disadvantage that, under their control, extreme mild reaction conditions must be ensured. They are very chronologically effective, and the resulting unsaturated hydrocarbon always contains traces of mercury.
Предлагаемый способ заключаетс в следуюп1ем.The proposed method is as follows.
В аппарат с внешним обогревом загруж-ают 14 вес.ч. твердого едкого кали , довод т температуру до 180° и приливают 6,б-днметнл-2-этилол-бицикло (1, 1,3)-гептеп-(2) со скоростью 11 вес. ч. с час. Отгонка образ ющегос углеводорода производитс над j)aзpeжeн ;e i (остаточное давление 30-35 мм рт. ст.).14 parts by weight are loaded into the unit with external heating. solid caustic potash, bring the temperature to 180 ° and pour 6, b-dnmetnl-2-ethylol-bicyclo (1, 1.3) -tepte- (2) at a rate of 11 wt. hour The distillation of the hydrocarbon produced is carried out over j) restraint; e i (residual pressure of 30–35 mm Hg).
В результате отгонки получают углеводородную смесь, в основном состо нпю из продукта дегидратации 6,6-д1иметнл-2-вп П1Л-б:1Ц кло- (1, .зГ-гептеи-(2). As a result of the distillation, a hydrocarbon mixture is obtained, mainly consisting of a 6,6-dimethyl-2-bp P1L-b dehydration product: 1C clo (1, 3H-heptaium- (2).
Выход составл ет 66-73% теоретически возможного и быть повыикчт до 82% при измененной скорости ладачи спирта.The yield is 66-73% theoretically possible and can be increased to 82% at an altered rate of alcohol supply.
