Description
При переработке фенхелевого мас-ла на пара-метоксибензальдегид (обепин) остаетс отход производства - мас.ю, не вонгедшее в реакцию .During the processing of fennel oil on para-methoxybenzaldehyde (obepin), the production waste remains - by mass, which does not react to the reaction.
Предложенный способ позвол ет использовать указанный отход производства дл получени ценного продукта фенхона и заключаетс в следующем.The proposed method allows the use of said production waste to produce the valuable fenchone product and consists of the following.
Масло, не вошедшее в реакцию при переработке фенхелевого масла на пара-метоксибензальдегид, выделенное из органической части продуктов реакции после проведени процесса окислени и после обработки их бисульфитом натри , подвергают перегонке с вод ным паром. Отбор прекращают тогда, когда на 100 ,мл воды переходит около 5 .мл масла. При этом выход легко летучих с паром веществ составл ет в среднем 60%.The oil that did not react during the processing of fennel oil to para-methoxybenzaldehyde, which was separated from the organic part of the reaction products after the oxidation process and after being treated with sodium bisulfite, is subjected to steam distillation. The selection is stopped when about 100 ml of oil are transferred to 100 ml of water. At the same time, the yield of volatile substances with steam averages 60%.
Легкое масло высушивают и разгон ют в колонке мощностью в б- 7 теоретических тарелок при флегмовом числе равном 12-15, и остаточно|М давлении в 10-12 жм. Улавливают фракцию с температурой кипени 191 -193,5°.Light oil is dried and dispersed in a column with a capacity of 6–7 theoretical plates with a reflux number of 12–15 and a residual | M pressure of 10–12 cm. The fraction with a boiling point of 191-193.5 ° is captured.
Выход фенхоновоГ фракции составл ет 27% к весу масла.The yield of the fenchone fraction is 27% by weight of the oil.
С целью увеличени выхода фенхона до 31% полученную при перегонке головную фракцию с температурой кипени 185-191,5° кип т т с азотной кислотой, вз той в двойном или тройном количестве от веса головной фракции.In order to increase the yield of fenchone up to 31%, the head fraction obtained by distillation with a boiling point of 185-191.5 ° is boiled with nitric acid taken in double or triple amount based on the weight of the head fraction.
