Description
Цитронелловое масло, поступающее в СССР из Китайской Народной Республики, служит сырьем дл получени цитронеллал , перерабатываемого в дальнейшем на гидрооксицитронеллаль и смесъ гераниола с цитронеллолом, используемую дл синтеза цитронеллал и получени цитронеллола.Citronella oil, supplied to the USSR from the People's Republic of China, serves as a raw material for the production of citronellal, further processed into hydroxycytronellal and a mixture of geraniol and citronellol, used to synthesize citronellal and to obtain citronellol.
При существзющем в насто щее врем технологическом режиме переработки цитронеллового масла некотора часть его (около 10%), в состав которой вход т сложные эфиры гераниола и цитронеллола, сесквитерпеновые спирты, эвгенол и другие вещества, остаетс неиспользованной .With the currently existing technological mode of processing citronella oil, some part of it (about 10%), which includes geraniol and citronellol esters, sesquiterpene alcohols, eugenol and other substances, remains unused.
Найден новый, способ переработки китайского цитронеллозого масла , включающий разделение спиртовой и неспиртовой части масла путем перегонки этого масла в присутствии борной кислоты, выделение цитронеллал фракционированной перегонкой неспиртовой части масла , заключающийс в том, что, с целью более полного использовани масла, фракцию неспиртовой части масла после отгонки цитронеллал подвергают омылению и затем выдел ют из нее смесь гераниола и цитронеллола известным образом, например посредством перегонки очистки через борные эфиры и повторной перегонки.A new method has been found for processing Chinese citronellose oil, including separation of the alcohol and non-alcohol parts of oil by distilling this oil in the presence of boric acid, separating the citronellals by fractionated distillation of the non-alcohol parts of oil, which means that in order to use the oil more fully, the fraction of non-alcohol part of oil after distillation, citronellal is subjected to saponification and then a mixture of geraniol and citronellol is separated from it in a known manner, for example, by distillation of the purification through boric acids. fira and re-distillation.
Пример. 4,3 кг остаточной части масла после выделени гераниола , цитронеллола и цитронеллал и 1,4 кг едкого натра, растворенных в 18,6 л воды, перемешивают 2 час. при 70°. После перегонки в вакууме получают 2 кг фракции с т. кип. 90-92° (при 4 мм остаточного давлени ), содержащей около 58% терпеновых спиртов (опреде- ено методом холодного ацетилировани ), и 0,48 кг фракции с т. кип. 92-100° (при 4 мм остаточного давлени ) с содержанием спиртов около 36%. Путем обработки борной кислотой и последующей перегонки спиртовой фракции получают продукт, содержащий около 77% терпеновых спиртов , счита на гераниол. Выход 40%.Example. 4.3 kg of residual oil after separation of geraniol, citronellol and citronellal and 1.4 kg of sodium hydroxide dissolved in 18.6 l of water are stirred for 2 hours. at 70 °. After distillation in vacuo, 2 kg of the fraction with m.p. 90-92 ° (at 4 mm residual pressure), containing about 58% of terpene alcohols (determined by cold acetylation), and 0.48 kg fraction with m.p. 92-100 ° (at 4 mm residual pressure) with an alcohol content of about 36%. By treatment with boric acid and subsequent distillation of the alcoholic fraction, a product containing about 77% of terpenic alcohols, calculated on geraniol, is obtained. Yield 40%.
