What are the main uses of 4-bromo cinnamic acid?
4 - Green wood acid, which was used in ancient times, was mostly used in both medicine and engineering.
In the realm of medicine, people in the past observed its properties, and found it had amazing effects. "Collection of Materia Medica" has been written, this material has the effect of detoxification. Where the skin is not good, those who are cured, apply the amount of green wood acid to it, which can help it. The reason is that green wood acid contains many active ingredients, which can inhibit the bacteria of medicine, cause pain, and promote the generation of new muscles. And its sex is good, and the stimulation of the muscles is small, so it is important to those who are affected. The ancient epidemic is caused, and in the treatment of some skin diseases, green wood acid also has a problem. It is not the main problem, but it cannot be helped.
In terms of workmanship, in lacquer, azuric acid has an extraordinary effect. Ancient painters know that adding azuric acid to the paint can make the paint more sticky. On the utensils, the adhesion is low, and it is not easy to fall off. And it can increase the durability of the paint. Years and months, the lacquer of the utensils can still remain intact, and the light is not low. Like the ancient fine lacquer, the lacquer is as new for a hundred years, and azuric acid is powerful. Furthermore, in the anti-treatment of some gold utensils, azuric acid is also used. It is made into a raw material, and the surface of the gold can be separated from the water in the air, and the gold can be preserved for a long time.
What are the physical properties of 4-bromocinnamic acid?
4-Proline is a kind of amino acid with unique physical properties. Its appearance is white crystalline powder, odorless and slightly bitter.
When it comes to solubility, 4-proline is soluble in water, about 16.1 grams per 100 ml of water at 25 ° C, but its solubility in organic solvents such as ethanol and ether is very small. This solubility characteristic has a great influence on many biochemical reactions and separation and purification processes.
4-proline has a high melting point, about 274 ° C. A higher melting point means that more energy is required to convert it from solid to liquid, which reflects strong intermolecular forces. In the molecular structure, due to the presence of hydroxyl groups, intramolecular and intermolecular hydrogen bonds are formed, which enhances the attractive force between molecules and increases the melting point.
Optical rotation is also an important physical property of 4-proline. It is a chiral molecule with the ability to rotate light. Under normal conditions, the specific optical rotation is about -76.5 ° (c = 2, in water). Optical rotation is of great significance in the fields of drug synthesis and food detection, because the biological activities of different optically active isomers may vary greatly.
In addition, the crystal structure of 4-proline also has characteristics. In the crystal, molecules are arranged in an orderly manner through hydrogen bonds and other interactions. The stability and arrangement of crystal structures affect their physical properties and chemical reactivity. For example, specific crystal structures or affect their ability to bind to other molecules. In protein structures, the unique crystal structure characteristics of 4-proline are crucial for maintaining the stability of protein spatial conformation.
What are the chemical properties of 4-bromo cinnamic acid?
4-Proline is one of the amino acids, and its chemical properties are very special.
In terms of its physical properties, 4-proline is a white crystalline powder with a stinky and slightly bitter taste. Its melting temperature is high, at 274 ° C. Due to the existence of molecular interaction forces, such as, it requires high energy to break the lattice and make it melt.
And the reaction activity of, the α-amino α-carboxyl group of 4-proline can be as typical as amino acid reaction. For example, the α-amino group can be reversed to form an acid, and it can also be reacted to amides under suitable conditions; the α-carboxyl group can be reversed to form a carboxylic acid of the phase, and can be esterified.
In addition, the 4-proline group is also an important active site. This group can be esterified, etherified, etc. In biological conditions, this group is often enzymatic and reactive to generate phosphorylation, which affects the function of 4-proline protein.
In addition, the molecular properties of 4-proline are increased due to the presence of the group, and the solubility phase in water is high. This property makes it easy to replace in biological aqueous solutions. In addition, the group can be used as a source or recipient, and the formation of three molecules of protein is very important, especially in tropoprotein, the formation of 4-proline is very important for supporting the three helices of tropoprotein.
What is the production method of 4-bromo cinnamic acid?
4 - The method of producing green wood is the method of ancient times. In the past, skilled craftsmen used to observe the natural things, study the truth, and extract green wood acid.
The first method is to obtain materials. The green wood of the good, this wood needs to be born in a suitable place, and it absorbs the essence of heaven and earth, and it is special. The soil of the land should be fertile, the water should be clear, and the light should be sufficient, so that the green wood of the land should be suitable.
Get the wood of the material, and burn it with fire. Place the green wood in the pottery, and slow the fire. The degree of fire is very important, and the wood coke is too high to lose its effect, and the wood coke is too low to improve its essence. Carboniferous fuel is used in the middle, and the firepower of the carboniferous fuel is uniform, which can be guaranteed.
In the heat of the stone, the bamboo tube is used to make it. In the water, the essence of green wood is contained, which is the shape of green wood acid. The bamboo tube is introduced into a porcelain pipe, and the water is filled in the middle. When the water coagulates, the liquid is dissolved. This liquid contains green wood acid.
It is used to cloth it. Take the dense cloth, and the liquid containing green wood acid is placed on it, and remove it, so that the liquid is more reliable.
Then the liquid is added to the kettle and boiled slowly over low heat. After boiling, it needs to be mixed to prevent local damage. When the water is steamed and the liquid is steamed, the degree of green wood acid will also increase.
When the liquid is at an appropriate degree, the fire will be stopped. When it is cold, the resulting product is green wood acid. The method of producing green wood acid in ancient times is the method of generating green wood acid.
What is the price range of 4-bromo cinnamic acid in the market?
4-Proline is in the market, and its price is low, and it is determined by it. This price is often low for various reasons, such as land, quality, and market supply and demand.
If the market below is roughly said, its price may range from 100 yuan to 1,000 yuan per kilogram. If the general product is low, and the market supply is low, or the price per kilogram is low. However, if the product is high-quality, or the market demand is prosperous and the supply is low, its price may rise to 1,000 yuan per kilogram.
If the raw materials are low and the industry is mature, the cost may fall, and the cost will be relatively flat. And if the raw materials are scarce in the land, coupled with the mention of low cost, the cost will be higher.
Furthermore, the difference in product quality is also low. Those with high quality and low quality must be affected by ordinary people. And the supply and demand of the city also affects the price. If you ask for more supply and less supply, you can't help it; if you supply and demand, you can't suppress it.
is to know the market size of 4-proline, and to observe the market size and the quality of the company, and to test the above reasons, you can get the best.
