Description
(54) СПОСОБ ВЫДЕЛЕНИЯ ГЕРАНИОЛА ИЗ ОТХОДОВ ФРАКЦИОНИРОВАНИЯ КОРИАНДРОВОГО МАСЛА(54) METHOD FOR ISOLATION OF GERANIOL FROM WASTES OF FRACTIONAL IMPORTANCE OF CORYANDRA OIL
первичных спиртов (как гераниол) не менее 90%.primary alcohols (like geraniol) not less than 90%.
Пример 2. Кубовый остаток фракционировани кориандрового масла имеет следую20Example 2. The bottoms residue of the fractionation of coriander oil has the following 20
щие состав и свойства: по от 1,4705 до 1,4710, первичных спиртов (как гераниол) 60%, спиртов, определ емых методом дегидратации (линалоол и гераниол) 70%, карбонильных соединений (камфора) 5%, сложных эфиров (как геранилацетат) 27%.composition and properties: from 1.4705 to 1.4710, primary alcohols (like geraniol) 60%, alcohols, determined by the dehydration method (linalool and geraniol) 70%, carbonyl compounds (camphor) 5%, esters (like geranyl acetate) 27%.
Кубовый остаток омыл ют 10%-ным водным КОН при нагревании на вод ной бане. Нейтральное масло подвергают ректификации на колонке эффективностью 5-8 т.т. при остаточном давлении 10-12 мм рт. ст., флегмовом числе 8-10. При температуре в парах до 110°С отбирают головную фракцию в количестве 10-12% от загрузки, по 1,4600-1,4650, спиртов, определ емых дегидратацией, не менее 80%. Эту фракцию присоедин ют к исходному кориандровому маслу. При температуреThe bottoms are washed with 10% aqueous KOH when heated in a water bath. Neutral oil is subjected to rectification on a column with an efficiency of 5-8 tons. with a residual pressure of 10-12 mm Hg. Art., reflux number 8-10. At temperatures in pairs up to 110 ° C, the head fraction in the amount of 10-12% of the load is taken, at 1.4600-1.4650, alcohols, determined by dehydration, not less than 80%. This fraction is added to the original coriander oil. At a temperature
112-114°С отбирают промежуточную фракцию , выход 44-45%, По 1,4700-1,4760, содержание гераниола не менее 80%. При повторной перегонке в таких же услови х из нее получают 40-42% гераниола.112-114 ° C select an intermediate fraction, yield 44-45%, 1.4700-1.4760, the geraniol content is at least 80%. When re-distilled under the same conditions, 40-42% geraniol is obtained from it.
Остаток содержит 88-90% гераниола и не более 2-4% сложных эфиров неизвестного состава. После перегонки с паром гераниол имеет следующие свойства: п 1.4760-1,4765, бромное число 200-207, первичных спиртов (как гераниол) не менее 90%.The residue contains 88-90% geraniol and not more than 2-4% esters of unknown composition. After steam distillation, geraniol has the following properties: 1.4760-1.4765, bromine number 200-207, primary alcohols (like geraniol) not less than 90%.
Предмет изобретени Subject invention
Способ выделени гераниола из отходов фракционировани кориандрового масла с применением ректификации, отличающийс тем, что, с целью увеличени выхода целевого продукта и одновременного выделени The method of separation of geraniol from waste fractionation of coriander oil using rectification, characterized in that, in order to increase the yield of the target product and the simultaneous separation
линалоола, исходное сырье перед ректификацией обрабатывают водным раствором едкой щелочи.linalool, the feedstock before rectification is treated with an aqueous solution of caustic alkali.
