Description
Амбриаль - ценное душистое вещество с запахом амбры - представл ет собой смесь, содержащую 70-757о 3-ме.тил-5-(И, 1, 10триметил-6- метилендекалил-5 )-пе11тен-2 - ал , 10-15% лактона 1, Г, б , 10-тетраметил-6оксидекалил-5-уксусной кислоты и 10-15% смеси органических кислот и углеводородов неизвестного строени .Ambrial, a valuable aromatic substance with an amber smell, is a mixture containing 70-757 about 3-me.til-5- (I, 1, 10-trimethyl-6-methylendecalyl-5) -met11-2-al, 10-15% lactone 1, g, b, 10-tetramethyl-6-oxydekalyl-5-acetic acid and 10-15% mixture of organic acids and hydrocarbons of unknown structure.
Сырьем дл производства амбриал служит склареол. Известен способ окислени склареола в толуольнол растворе хромовой смесью при 80-85° С с последующей пиролитической дистилл цией продукта окислени в вакууме. В результате происход щей при этом дегидратации образуетс и отгон етс амбриаль с выходом 55-58%.The raw material for the production of ambrial is sclareol. A known method for the oxidation of sclareol in toluene solution to a chromium mixture at 80-85 ° C, followed by pyrolytic distillation of the oxidation product in vacuum. As a result of the dehydration occurring during this process, ambrial is formed and distilled off in a yield of 55-58%.
Предлагаетс способ получени амбриал окислением склареола хромовой смесью в ксилольном растворе при температуре 95-100 С с последующей дегидратацией асканитом при кип чении. Выход продукта увеличиваетс до 75-78%, а также упрощаетс аппаратурное оформление процесса на стадии дистилл ции: отпадает необходимость применени охлаждаемых ловущек.A method is proposed for the preparation of the ambrial by the oxidation of sclareol with a chromium mixture in a xylene solution at a temperature of 95-100 ° C, followed by dehydration with ascanite during boiling. The yield of the product is increased to 75-78%, and the instrumentation of the process at the distillation stage is also simplified: there is no need to use cooled traps.
Приеме р. 103 г склареола (т. нл. 102- 103° С) раствор ют в 600 мл ксилола и 103 г уксусной кислоты. После растворени склареола добавл ют раствор 67 г двухромовокислого натри в 120 мл воды. Смесь подогревают до 95° Сив течение 30 мин приливают раствор 88 г концентрированной серной кислоты в 48 мл воды, поддерлсива температуру смеси в пределах 95-100° С, после чего реакционную массу выдерживают еще 30 мин при той же температуре. Ксилольпый раствор продуктов окиалени , полученный после отделени квасцов, промывают водой до полного удалени серной кислоты. Нейтральный раствор кип т т с водоотделителем дл удалени следовReception p. 103 g of sclareol (T. Nl. 102–103 ° C) are dissolved in 600 ml of xylene and 103 g of acetic acid. After dissolving sclareol, a solution of 67 g of sodium bichromate in 120 ml of water is added. The mixture is heated to 95 ° Civ. For 30 minutes, a solution of 88 g of concentrated sulfuric acid in 48 ml of water is poured, keeping the mixture temperature in the range of 95-100 ° C, after which the reaction mixture is kept for another 30 minutes at the same temperature. The xylene solution of the oxidation products, obtained after the separation of alum, is washed with water until complete removal of sulfuric acid. The neutral solution is boiled with a water trap to remove traces.
влаги, затем добавл ют 3 г асканита и кип т т с водоотделителем в течение часа: в процессе кип чени в присутствии катализатора - асканита происходит отщепление воды от продукта окислени . После полного отделени воды (около 5 мл) раствор охлаждают, фильтруют и перегон ют в вакууме. Получают 80 г амбриал с т. кип. 160-190° С (5мм). Выход продукта 77,5i%.moisture, then 3 g of ascanite is added and boiled with a water separator for an hour: in the process of boiling in the presence of a catalyst, ascanite, water is separated from the oxidation product. After complete separation of the water (about 5 ml), the solution is cooled, filtered and distilled in vacuo. Get 80 g of the embryo with t. Kip. 160-190 ° С (5mm). The product yield 77,5i%.
