Embodiment 1

[0025] A kind of purification method of lavender essential oil, comprises the following steps:

[0026] (1) Cleaning: select fresh lavender, wash it with clean water, and crush it;

[0027] (2) Ultrasound: add 60% isopropanol solution 80 times the weight of lavender to the pulverized material, and ultrasonicate at 100KHz and 800W for 60 minutes;

[0028] (3) Extraction: Add the sonicated solution into a separatory funnel, and at the same time add ethyl acetate three times the volume of the sonicated solution, oscillate and mix for 5 minutes, and separate the organic phase after standing for 5 minutes;

[0029] (4) Rectification: Put the extracted organic phase into a precision distillation tower filled with pulse packing, vacuum continuous precision distillation to remove impurities in the organic phase, and obtain an essential oil with a purity higher than 99%.

Embodiment 2

[0031] A kind of purification method of lavender essential oil, comprises the following steps:

[0032] (1) Cleaning: select fresh lavender, wash it with clean water, and crush it;

[0033] (2) Ultrasound: add 30% ethanol solution 50 times the weight of lavender to the pulverized material, and ultrasonicate at 50KHz and 1000W for 90 minutes;

[0034] (3) Extraction: put the ultrasonicated solution into a separatory funnel, and at the same time add petroleum ether with 1 times the volume of the ultrasonicated solution, shake and mix for 10 minutes, and separate the organic phase after standing for 15 minutes;

[0035] (4) Rectification: Put the extracted organic phase into a precision distillation tower filled with metal plate corrugated structured packing, vacuum continuous precision distillation to remove impurities in the organic phase, and obtain an essential oil with a purity higher than 99%.

Embodiment 3

[0037] A kind of purification method of lavender essential oil, comprises the following steps:

[0038] (1) Cleaning: select fresh lavender, wash it with clean water, and crush it;

[0039] (2) Ultrasound: Add 70% butanol solution 100 times the weight of lavender to the pulverized material, and ultrasonicate at 200KHz and 500W for 30 minutes;

[0040] (3) Extraction: put the ultrasonic solution into a separatory funnel, and at the same time add methylene chloride twice the volume of the ultrasonic solution, shake and mix for 8 minutes, and separate the organic phase after standing for 10 minutes; (4) Distillation : Put the extracted organic phase into a precision distillation tower filled with wire mesh structured packing, vacuum continuous precision distillation to remove impurities in the organic phase, and obtain an essential oil with a purity higher than 99%.

Abstract

The invention discloses a purification method for lavender essential oil. According to the method, lavender essential oil with the purity higher than 99% is obtained by conducting the steps of washing, ultrasonic processing, extracting, rectifying and the like on lavender. Lavender essential oil high in purity and safe is extracted from natural materials, can be applied in the fields of cosmetics, medicine and the like, and is good in market prospect. The method is easy and convenient to operate, low in manufacturing cost and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals and relates to a method for purifying lavender essential oil. Background technique [0002] Plant essential oils are the unique aromatic substances extracted from plants, which are extracted from the flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbal plants by distillation and pressing. Because aromatherapy essential oils are highly volatile and have small molecules, they are easily absorbed by the human body and can quickly penetrate into the internal organs of the human body to excrete excess components. The whole process only takes a few minutes, and the fragrance of the plant itself also directly stimulates the brain. The secretion of the pituitary gland, the secretion of enzymes and hormones, etc., balance the functions of the body, and play the role of beauty and skin care. However, traditionally extracting plant essential oils from natural raw materials such as flow...
