The glycerin is a chemical formula C ₃ H ₅ OH) ₃ with a CAS number of 56-81-5, and is a colorless, odorless liquid. It has very strong viscosity, but it is a fat or oil component like fatty acids, and is obtained by decomposing fats and oils industrially. Glycerin is a trihydric alcohol with three hydroxyl groups. It is a colorless, sticky liquid, has hygroscopicity, a little sweetness, and has a melting point of 20℃ and a boiling point of 290℃. In addition to being used as a synthetic raw material such as glyphtal resin, glycerin is used in drugs such as lubricants or ointments, antiseptic agents for cigarettes and cosmetics, refining agents, etc., as well as anti-freezing agents, coolants, It is an important material with a very wide application such as printing ink.

In nature, about 0.08% of potassium chloride is contained in seawater and is obtained from a mineral called sylvine or sylvite. The crystals belonging to the white tetragonal system (正方晶系) and naturally produced are mixed with bitter taste and salty taste. The potassium chloride is well soluble in water, conducts an electric current well, and contains potassium ions, an alkali metal element, and thus undergoes a purple flame reaction. In addition, the potassium chloride is industrially used as a raw material for preparing a potassium salt, and in a laboratory, it is used as a buffer solution and an electrode solution. The single crystal of potassium chloride (KCl) can be used in the manufacture of a prism or cell window used for infrared absorption measurement, and is used as a heat treatment agent, photographic reagent, medicine, and the like.

The sodium chloride is a compound of sodium and chlorine and is the main component of edible salt. The proportion of salts in seawater is the largest, and sodium chloride is well soluble in water, which is the same polar solvent, because sodium ions (Na+) and chloride ions (Cl-) are combined to have a polar structure. In addition, the crystal structure of sodium chloride is a form in which each atom having an octahedron has 6 nearest neighbors.

If the particle size of the leaves of the Hwangchil tree is pulverized to less than 500 μm in the above step, it takes a long time to crush, and the particles are too small to cause agglomeration between particles in a later process, and when the particles exceed 2500 μm There may be a problem in that it is difficult to effectively extract useful ingredients from the leaves of the hwangchil tree.

Next, the pulverized hwangchil tree leaf extract can be obtained by applying ultrasonic waves in an atmosphere of low temperature and reduced pressure to remove solids.

In the above step, after preparing a mixture by mixing the pulverized hwangchil tree leaves with a solvent, it is introduced into an ultrasonic extractor to apply ultrasonic waves to the mixture, and the solids contained in the mixture are mixed with a known strainer such as a sieve, etc. Hwangchil tree leaf extract can be prepared by removing it using, and the solvent is mixed in a weight ratio of 1000 to 2000 parts by weight based on 100 parts by weight of the pulverized hwangchil tree leaf, and the solvent is water or carbon number 1 to 4 Any one or more solvents selected from alcohols of (C1 to C4) may be used.
