Embodiment 1

[0027] (1) Preparation of Yuanbao maple oil:

[0028] (1) Shelling: Control the moisture content of the maple seeds in the range of 8-12%, and put them into a special peeling machine for maple seeds for peeling treatment. After the treatment, the shell kernels are separated by winnowing to obtain maple seeds.

[0029] (2) Oil extraction: the shelled and separated Yuanbao maple kernels are subjected to moisture adjustment, so that the moisture content is controlled within the scope of 8-10%, and oil extraction is carried out with a 90-type oil press, and the oil yield is more than 85%.

[0030] (2) Preparation of ethyl nervate:

[0031] (1) Pretreatment: filter the Yuanbao maple oil to remove impurities, add a concentration of 5% sodium hydroxide solution according to the weight of 0.8% of the weight of Yuanbao maple oil and add alkali, the reaction temperature is 50°C, the stirring speed is 40r / min, and the time is 30 minutes, after the reaction is completed, the temperature ...

Embodiment 2

[0036] (1) Preparation of Ingot Maple Oil: Same as Example 1.

[0037] (2) Preparation of ethyl nervate:

[0038] (1) Pretreatment: filter the Yuanbao maple oil to remove impurities, add a concentration of 4% sodium hydroxide solution according to the amount of alkali added to 1.0% of the weight of Yuanbao maple oil, the reaction temperature is 40°C, the stirring speed is 30r / min, and the time is 60 minutes, after the reaction is completed, the temperature is rapidly raised to 80°C at a rate of 1°C / hour, and the temperature is kept for 6 hours to completely separate the soap particles, remove the oil residue and wash with water for 3 times, and then remove the water.

[0039] (2) Ethyl esterification: After mixing 100 parts by weight of Yuanbao maple oil with 50 parts by weight of absolute ethanol and 1.2 parts by weight of basic catalyst potassium hydroxide, carry out esterification reaction, and react two Hours, after the reaction, wash with water 3 times to remove glycerin...

Embodiment 3

[0043] (1) Preparation of Ingot Maple Oil: Same as Example 1.

[0044] (2) Preparation of ethyl nervate:

[0045] (1) Pretreatment: filter the Yuanbao maple oil to remove impurities, add a concentration of 6% sodium hydroxide solution according to the amount of alkali added to 0.5% of the weight of Yuanbao maple oil, the reaction temperature is 30°C, the stirring speed is 60r / min, and the time is After the reaction is completed, the temperature is rapidly raised to 80°C at a rate of 1°C / hour, and the temperature is kept for 8 hours to completely separate the soap particles, remove the oil residue and wash twice with water, and then remove the water.

[0046] (2) Ethyl esterification: after mixing 100 parts by weight of ingot maple oil with 60 parts by weight of absolute ethanol and 1.5 parts by weight of basic catalyst potassium hydroxide, react three Hours, after the reaction, wash with water twice to remove glycerol, alkali, and excess ethanol.

[0047] (3) Molecular disti...

Abstract

This invention relates to a method for extracting nervonic acid from Acer truncatum oil by molecular distillation. The method solves the problems of complex procedures, easy emulsification, high product acid value and low product purity faced by present technique. The method comprises: (1) preparing Acer truncatum oil; (2) performing deacidification treatment on Acer truncatum oil, removing oil foot, washing with water, and dehydrating; (3) mixing Acer truncatum oil, absolute ethanol and alkaline catalyst, esterifying, washing with water, and separating to obtain ethyl nervonate; (4) performing molecular distillation in different vacuum conditions and temperatures, and collecting the product.

Description

Technical field: [0001] The invention relates to the technical field of fatty acid preparation technology, in particular to a method for extracting nervous acid from ingot maple oil by molecular distillation technology. Background technique: [0002] Nervous acid, also known as sharkic acid, chemically named cis-15 tetradecenoic acid, is a long-chain unsaturated fatty acid, mainly present in human brain proteins, retina, sperm and nerve tissues in the form of glycosphingolipids and sphingomyelin middle. A large number of medicines have proved that nervous acid can restore the activity of brain cell terminals, promote the growth and development of nerve cells, and have certain curative effects on cardiovascular and cerebrovascular diseases and autoimmune deficiency diseases. Therefore, the extraction and application of nervonic acid is of great significance and value. The relevant introductions seen so far include extracting from seaweed plants, shark oil and shark brain, b...
