The two immortal vines and the four-legged grass have their own qualities, which are very different.

The two immortal vines have a peaceful nature, sweet and slightly bitter taste. Looking at its shape, the vines are slender, meandering and climbing, and the leaves are oval, green and shiny. Its quality is gentle, although slender and tough, it can be woven and can be used for practical purposes. As medicine, it has the effect of dredging collaterals and relieving pain, removing wind and dehumidifying. In the genus of arthralgia, those with joint pain and unfavorable flexion and extension can use it to relieve their symptoms. Because of the nature of vines, it is good for dredging meridians and collaterals, and smoothing qi and blood.

The four-legged grass has a square stem and four edges, which is different from the shape of regular grass. Its leaves are opposite to each other, with teeth on the edge, green in color and thin in quality. Cool in nature and slightly pungent in taste. With its cool nature, it has the power of clearing away heat and detoxifying. It can be used at the beginning of carbuncle swelling and sores, and applied internally and externally to dissipate poisonous evil. It can also cool blood and stop bleeding. It can also be used in case of hemoptysis, hemoptysis, and other diseases caused by blood-heat delusion. Its qi is clear and rises and disperses, and it can penetrate and express evil. It is also curative for exogenous wind and heat, fever, and sore throat.

As for the difference in physical properties between the two, Erxian vine focuses on dredging meridians and collaterals, and is biased towards walking and channeling, so it is important to adjust qi and blood; the four-legged grass is the power of clearing away The nature of the two immortal vines is relatively gentle, acting on the inside and slowing down the picture; the nature of the four-legged grass is slightly fierce, acting on the outside and quick-acting. They are all treasures in the grass, used in medicine, and each is good at winning the field, which cannot be ignored.

What are the chemical properties of 2,3,5,6-tetrafluorobenzene-1,4-diformaldehyde

Diethylene glycol and tetraethylene glycol are organic compounds, both of which belong to polyhydroxy ethers.

Diethylene glycol, the appearance is colorless, odorless, transparent and hygroscopic viscous liquid, the taste is slightly sweet and spicy. It can be miscible with water, ethanol, acetone, ether, ethylene glycol, and insoluble in organic solvents such as benzene, toluene, and carbon tetrachloride. Diethylene glycol is flammable, and can be burned in open flames and hot topics. Its vapor and air can form explosive mixtures. Its relative density is 1.1164, boiling point 245 ° C, melting point -6.5 ° C.

Tetraethylene glycol, presented as a colorless to light yellow viscous liquid, has hygroscopicity. It is miscible with water and alcohol, slightly soluble in ether, insoluble in benzene, toluene, etc. Tetraethylene glycol is flammable, with a relative density of 1.1254, a boiling point of 327.3 ° C, and a melting point of -5.6 ° C.

From a chemical perspective, both contain multiple hydroxyl groups, which makes them hydrophilic and reactive. Hydroxyl groups can participate in many chemical reactions, such as esterification reactions, etherification reactions, etc. Due to the existence of ether bonds in the molecular structure, the chemical stability of the two is relatively good, but under certain conditions, ether bonds can undergo reactions such as breaking. They are widely used in industrial fields, such as as as solvents, plasticizers, moisturizers, etc. However, if diethylene glycol is accidentally ingested into the human body, it may cause harm to health. When using and storing such compounds, appropriate safety regulations and operating procedures must be followed according to their chemical properties and characteristics.

What are the synthesis methods of 2,3,5,6-tetrafluorobenzene-1,4-diformaldehyde

To combine mercury arsenic and erbium tetrahydrate, the method is as follows:
First prepare various things, take two parts, three parts, five parts, six parts, this is required for erbium tetrahydrate; take one part, four parts, as the material of mercury arsenic.
First prepare erbium tetrahydrate, and in a clean vessel, add two, three, five, and six doses in turn. Slow fry over a slow heat, and add stirring during this time to make the things blend. When its color changes like light gold and its gas is like orchid, this erbium tetrahydrate is complete.
Second make mercury arsenic, take another container, and pour one and four materials. Calcined with martial fire, seeing purple smoke rising, and smelling a strange fragrance, quickly withdraw its fire. Wait for it to be a little cold, use water to make it fertile, its quality is firm and clear, and mercury diarsenic is enough.
Finally combine the two, pour the formed four water erbium on the mercury diarsenic, and stir slowly. Seeing the brilliance flickering, the sound is like a phoenix, then the synthesis is also successful. However, this technique needs to be practiced with caution, it is related to the change of physical properties. If there is a slight mistake, it may cause disaster. Make sure the operator is attentive and does it according to the recipe.

What is the price of 2,3,5,6-tetrafluorobenzene-1,4-diformaldehyde in the market?

Looking at today's market, the price trend of bismuth and germanium tetrachloride is of great concern to everyone. Bismuth is above the market, and its price often fluctuates due to various reasons. In the past, it relied heavily on the output of mineral sources, but the abundance of mineral sources really depended on the right time, the right place and the right people. If the ore veins are rich and the mining is smooth, the supply will be sufficient, and the price will stabilize; if the ore sources are scarce and the mining is difficult, the price will rise. In addition to the demand of the city, if many workshops compete to buy it for casting products, the price will also rise; if there is no demand, the supply will exceed the demand, and the price will fall.

As for germanium tetrachloride, the change in its price is not determined by a single factor. Most of it comes from the art of refining, and the quality of the art is related to the amount of output. Those who are skilled in the art produce more and the cost is reduced, and the price is close to the people; those who are poor in the art produce less and the cost is high, and the price must be expensive. And its use involves a wide range, and it is important for optoelectronics and semiconductors. If such industries are booming and demand surges, the price will rise; on the contrary, the industry is sluggish and demand is sluggish, and the price will not improve.

Today, although it is difficult to determine the exact price of the two, according to the market situation, if the source of bismuth is safe and the demand is stable, the price may fluctuate slightly within a certain range; if germanium tetrachloride is refined, the industry demand will increase slightly, and the price may rise slightly. However, the market situation is changing rapidly, this is just speculation, and the actual price still depends on the current supply and demand, the direction of politics, and the new changes in technology.
