Description
Известные способы получени уксусного и мурапьнного эфира изоборнеола путем обработки органической кислотой камфена в присутствии катализатора но позвол ют полностью использовать вводимую в реакцию органическую кислоту и камфон.Known methods for the preparation of isoborneol acetic and muraphenate ester by treating camphene with an organic acid in the presence of a catalyst, but allow the organic acid introduced into the reaction and camphor to be fully utilized.
Описываемый способ не имеет указанных недостатков и, кроме того, дает возможность отделнть но окопчапип 1)еакции продукт от катализатора, отогнать от эфира непрореагировавнгую кислоту вместе с основной массой ненрореагировавшего камфе1га и возвратить их в процесс .The described method does not have the indicated drawbacks and, moreover, makes it possible to separate but the entrapment of the 1) product from the catalyst, to drive off unreacted acid from the ester together with the bulk of the unreacted camper and return them to the process.
Предлагаемый способ заключаетс в TOJ, что тер11фп1;ацию осуществл ют пзбыткои высококонцрнтрированной opraniiческой кислоты в присутствии нерастворимых в реагирующих веществах катализсчтороп , так1гх, как катиоиообчеииые с.мо.11,1 или сульфпугли. Причем процесс ()Т(риф111;;1ЦИ1г каМ111(иа мо;|;ет oc.ynioc.ritл тьс в непрерьпиго денстпующей нрототной системе.The proposed method consists in TOJ, which is termed 11fp1, and the reaction is carried out by means of highly highly concentrated opranic acid in the presence of catalysts that are insoluble in the reactants, such as cationic complexes of cm. 11.1 or sulfpugly. Moreover, the process () T (riff111 ;; 1ЦИ1г каМ111 (and мо; |; em oc.ynioc.rit is in the continuity of the denstupuyu nrotrotnoy system.
II р и м е р. В обогреваемую до 60° бюретку дпаметрои 20 мм. помещают 35 г. катиопообмеппой смолы, полученной кондспгацмпй п-рульфофепола г. формальдегидом , и через пенрерыпно пропускают 28,5 /о-ный раствор камфспа в лед ной уксусной кислоте со скоростью до 3,3 мл. в мпнуту. После отгонки под вакуумом не вошедикй в реаьцию уксусной К1 слоты получают зфпр.II p and me. In a burette heated to 60 °, diameter of 20 mm. 35 g of cathiopoobmep resin obtained by Kondpatzmpy p-rulphoepol, formaldehyde, are placed, and a 28.5 / o solution of campfys in glacial acetic acid is passed through the pen-rape system with a speed of up to 3.3 ml. in mn. After distilling under vacuum, the slots that do not enter into the reaction of acetic K1 receive zfpr.
При работе па указанных ско1111ст х пропускани реагируюп1ей смеог через слой катализатора и нрн рабочей емкости апнарата 1 л. должно превращатьс в эфир 15 кг. камфена в сутки.When working on the specified transmission speeds of reactive mixture through the catalyst bed and the nrn of the working capacity of 1 liter apnarata. should turn into a 15 kg air. Camphene per day.
