Problems solved by technology

[0006] Judging from the current equipment for the extraction, purification and concentration of natural organic substances in animals and plants, the extraction, purification and concentration of most natural organic substances are carried out in a single step, and the experimental steps of extraction, purification and concentration must be completed quickly The integrated operation is more difficult
In order to achieve the purpose of the experiment, multiple sets of experimental equipment must be assembled. The experimental process is complicated and time-consuming, resulting in a certain waste of resources. The simultaneous use of multiple sets of experimental equipment will occupy more space, resulting in a waste of laboratory space.

Embodiment 1

[0035] Embodiment 1 extracts cinnamon oil from cassia twig leaves

[0036] Such as Figure 4 As shown, 50g of pulverized cassia twig leaves (the crushed cassia twig leaves fragments can not be less than the diameter of the filter screen mesh in the extraction cylinder) is gently poured into the extractor with filter screen, and 95wt% 200mL of ethanol solution, according to Figure 4 Assemble the instrument bottle, close the water vapor conduit switch A and the switch C between the reflux and distillation device, open the reflux extraction switch B, check the airtightness of the experimental device in the extraction part, then heat the reflux extraction flask 5 for reflux extraction, siphon 4~ After 5 times of reflux extraction, the color of ethanol in the flask 5 gradually changes to dark brown, and the color of the solution in the extraction cylinder becomes very light. When the reflux liquid in the extractor 7 just siphons down, stop heating, turn off the reflux extraction ...

Embodiment 2

[0037] Embodiment 2 extracts nicotine from tobacco

[0038] Such as Figure 4 As shown, 20g of crushed tobacco leaves (the fragments of the crushed tobacco leaves cannot be smaller than the diameter of the filter mesh in the extraction cylinder) after being treated with 10wt% hydrochloric acid and 5wt% sodium hydroxide are gently poured into the extractor with a filter screen , add ether 200mL to the reflux extraction flask 5, according to Figure 4 Assemble the instrument bottle, close the water vapor conduit switch A and the switch C between the reflux and distillation device, turn on the reflux extraction switch B, check the airtightness of each part of the extraction device, and then heat the reflux extraction flask 5 with a water bath for reflux Extraction, when the color of the crushed tobacco leaves becomes lighter, stop heating after the reflux liquid in the extractor has just been siphoned down, turn off the reflux extraction switch B, turn on the water vapor conduit...

Abstract

The invention belongs to the technical field of natural product purification and relates to an experiment device integrating extraction and water steam distillation separation. The experiment device integrating extraction and water steam distillation separation comprises a water steam generator, a T-shaped tube, a condensing tube, an extractor, a reflux extraction flask and a distillation and purification device. The water steam generator is connected into the reflux extraction flask through the T-shaped tube. The condensing tube is communicated with the reflux extraction flask through the extractor. The reflux extraction flask is communicated with the distillation and purification device. The experiment device integrating extraction and water steam distillation separation can be used in aunited integration way, part of experiment apparatuses of the experiment device can be also independently used, flexible use is achieved according to different experiment requirements, the experimenttime can be saved, the experiment space can be decreased, and the experiment device can be randomly detached and is convenient to clean.

Description

technical field [0001] The invention belongs to the technical field of natural product purification, relates to an experimental instrument capable of integrated operation, in particular to an experimental device integrating extraction and steam distillation and separation. Background technique [0002] There are a variety of animals and plants in nature, all of which contain a large amount of natural organic compounds, most of which exist in the natural products of various parts of animals and plants and play a pivotal role in human life and production. So how to extract and further purify and concentrate these useful natural products is particularly important. As early as the middle of the 18th century, due to the progress of science and technology and the requirements of social development, humans initially mastered the extraction and separation technology of natural products. But at the end of the 18th century, purer organic matter could be extracted from living organisms...
