Description
Обычные способы обезвоживани 96-98%-кого изопропилового спирта , например, кип чение его над свежепрокалеииой окисью кальци с последующей отгонкой, азеотропна разгонка с бензолом, или св заны со значительными потер ми спирта, или требуют применени мощных ректификационных колонн, длительного времени и больщого количества бензола.Conventional methods for the dehydration of 96-98% isopropyl alcohol, for example, boiling it over fresh calcium carbonate, followed by distillation, azeotropic distillation with benzene, or associated with significant loss of alcohol, or require the use of powerful distillation columns, a long time and amounts of benzene.
Предлагаемый метод, .лишенный указанных недостатков, отличаетс тем, что обезвоживание изонропилового спирта производ т изопроиилатом алюмини за счет разложени его водой, содержащейс в обезвоживаемом спирте, и св зывани ее по уравнениюThe proposed method, which does not require these drawbacks, is characterized in that the dehydration of isopropyl alcohol is produced by aluminum isopropylate by decomposing it with water contained in the dehydrated alcohol and binding it according to the equation

Освобождающийс при обезвоживании из изспропилата спирт возвращаетс в производство. Дл полного обезвоживани берут избыток изопропилата алюмини в количестве 5-10%.The alcohol released from dehydration from isopropyl is returned to production. For complete dehydration take an excess of aluminum isopropyl in the amount of 5-10%.
Операцию обезтзоживаии совмещают с операцией получени в том же аппарате изопропилата алюмини и весь процесс провод т следующим образом.The operation of deactivating is combined with the operation of obtaining aluminum isopropylate in the same apparatus and the whole process is carried out as follows.
В кубе, снабженном мещалкой, паровой рубащкой и обратным холодильником , получают известным способом изопропилат алЕОмини из изопропилового спирта, вз того в количестве 150% от теории, и алюмини . По получеини изоиропилата алюмини в этот же куб заливают изопропиловый спирт, который требуетс обезводить. После этого реакционную массу размещивают на холодз в течение 1-2 часов. Затем обратный хо.юдильиик иереключают на работу в качестве пр мого и обезвоженный спирт отгои ют. Еслк в кубе остаетс aлюми -н й, то он может быть использован дл следующей операции иолучеии изопропилата алю мини . Потери сиирта при обезвоживании составл ют 1-2%. Обезвоживание можио производить концентркрованным раствором изопроиилата алюмини в безводном изопропиловом спирте.In a cube equipped with a broom, steam scrubber and reflux condenser, aEOmini isopropylate from isopropyl alcohol, taken in an amount of 150% of theory, and aluminum is obtained by a known method. In half an isopropyl aluminum, isopropyl alcohol is poured into the same cube, which must be dehydrated. After that, the reaction mass is placed on the chill in 1-2 hours. Then, the reverse cold drink is switched to work as a direct and dehydrated alcohol is distilled off. If the cube remains aluminum, then it can be used for the next operation and the recovery of aluminum isopropylate. The loss of sheerat during dehydration is 1-2%. Dehydration can be carried out with a concentrated solution of aluminum isopropylate in anhydrous isopropyl alcohol.
