Description
Обычно нерол-душистое вещество получают из масла гелихризум. Известен также способ получени его синтетическим путем из цитрал и нерал .Typically, a non-fragrant substance is obtained from helihrizum oil. There is also known a method for preparing it synthetically from citral and nonral.
Предметом изобретени вл етс способ перевода цитрал в нерол, при котором получают нерол с высокими выходами.The subject of the invention is a method for converting citral to nerol, in which nerol is obtained in high yields.
Особенность способа состоит в том, что гидрирование цитрал ведут под давлением .100-200 атм и при температу|зе 100-150° в присутствии медного ката.чнзатора, осажденного на носителе. Гид1)1фование может пропзводитьс в растворителе или без него.The peculiarity of this method is that the hydrogenation of citral is carried out under a pressure of .100-200 atm and at a temperature of 100-150 ° in the presence of a copper cathode deposited on the carrier. Hydro1) 1funding can be carried out in or without solvent.
Пример. 1000 г цитра.т гидрируютс в автоклаве в присхтсим-шExample. 1000 g of citra.t are hydrogenated in an autoclave in drying
50 г катализатора под давлением 100-200 атм и те.мпературе 100 150 до пог.тои1,ени иеобходимого ко.тичества водорода.50 g of catalyst at a pressure of 100–200 atm and a temperature of 100–150, up to 1 hour, of the required amount of hydrogen.
После отделени катализатора и nepeiOHKH в вакууме получают 980 г продукта, содержап1его около 90% перо.та и ЮА гераниол.а п Ц1ггро1ге ,1,тола.After separation of the catalyst and nepeiOHKH in vacuo, 980 g of product are obtained, containing about 90% of the pen. And SOA geraniol.
