Embodiment 1

[0012] Weigh 4 parts of 9.2g (7.3ml) of glycerol, put them into 4 cryogenic bottles, then add 11.6g lysine, 20.4g tryptophan, 16.5g phenylalanine and 14.9g methionine respectively, Add appropriate amount of water to dissolve, pre-freeze at -80°C for 0.5h, and then freeze-dry for 8h. eutectic solvent.

Embodiment 2

[0014] Weigh 4 parts of glycerol 9.2g (7.3ml), put it into 4 cryogenic bottles, then add 40.7g lysine, 71.4g tryptophan, 57.8g phenylalanine and 52.2g methionine respectively, Add appropriate amount of water to dissolve, pre-freeze at -80°C for 1 hour, and then freeze-dry for 12 hours. Solvent.

Embodiment 3

[0016] Weigh 4 parts of glycerin 9.2g (7.3ml), put into 4 cryogenic bottles, then add 11.9g threonine, 13.2g isoleucine, 13.1g leucine and 11.7g valine respectively, respectively Add an appropriate amount of water to dissolve, pre-freeze at -80°C for 0.75 hours, and then freeze-dry for 10 hours. The obtained liquid is glycerol-threonine, glycerol-isoleucine, glycerol-leucine and glycerol-valine deep eutectic solvent .

Abstract

The invention relates to a preparation method of a glycerin-amino acid deep eutectic solvent. According to the method, glycerin and amino acids are mixed according to a certain molecular ratio and dissolved in a proper amount of water, low-temperature pre-freezing is performed, then freezing and drying are performed, and obtained liquid is the glycerin-amino acid deep eutectic solvent. The technology is simple, cost is low, the obtained deep eutectic solvent can serve as extracting agents, microbial protecting agents and reaction media and is widely used in the industries of food, medicine, biotechnology and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a preparation method of a glycerol-amino acid deep eutectic solvent. Background technique [0002] Deep eutectic solvent is a deep eutectic mixture composed of two or more components, also known as a greener liquid. It is usually a eutectic mixture composed of a certain stoichiometric ratio of hydrogen bond donors and hydrogen bond acceptors. In addition, due to the low cost of raw materials for its preparation, the preparation process is a 100% atom-economical reaction, there is no three-waste problem in the preparation process, the product is easy to biodegrade, and has no harm to the environment and no toxic side effects, so it is a new type that can be widely used. Green solvent. Deep eutectic solvents are widely used in organic reactions, electrochemistry, material preparation and extraction and separation engineering. [0003] In 2001, Abbott and others prepared a series of...
