Aminoguanidine-1,3,6-triazine tricarboxylic acid, the physical properties of this substance are as follows:
Its appearance is often white to light yellow crystalline powder, and the texture is more delicate. In terms of solubility, it has a certain solubility in water, but the solubility is not very high, and the solubility in hot water is slightly better than that in cold water. In organic solvents, such as common ethanol, ether, etc., its solubility is relatively poor, and it is difficult to dissolve in large quantities.
When it comes to melting point, aminoguanidine-1,3,6-triazine tricarboxylic acid has a high melting point, and it needs to reach a specific temperature to undergo a phase transition. This property allows it to maintain solid state stability under normal temperature environments.
In terms of density, its density is moderate, similar to that of most organic compounds. This density property makes it in the system when participating in various experimental operations or industrial processes, and the distribution and precipitation comply with the relevant material laws.
Furthermore, it has a certain degree of hygroscopicity. If exposed to a high humidity air environment, it will absorb water vapor in the air, causing some changes in its own properties, such as agglomeration. Therefore, in terms of storage, it is necessary to pay attention to keeping the environment dry to maintain its original physical form and properties stable and avoid adverse effects on subsequent use due to moisture absorption.

Hydroxyurea-1,3,6-triazine acid is a very important chemical substance with unique and diverse chemical properties.
Let's talk about hydroxyurea first, which is weakly acidic. Because of the hydroxyl group (-OH) in the molecule, the hydrogen atoms on the hydroxyl group can undergo weak ionization, which in turn exhibits acidic characteristics. It also has reductivity, which is derived from the properties of chemical bonds within the molecule. Under suitable conditions, it can provide electrons to other substances and undergo oxidation reactions on its own. For example, in some redox systems, hydroxyurea can participate in the reaction by virtue of its reductivity, which affects the reaction process.
Let's talk about 1,3,6-triazine acid, which is acidic. The molecule of this substance contains a carboxyl group (-COOH), which is a typical acidic functional group, which can ionize hydrogen ions in water and make the solution acidic. 1,3,6-triazine acid also has certain stability, which is due to the special chemical bonds and spatial configuration in its molecular structure. This stability makes it less prone to decomposition or other violent chemical reactions under normal conditions, and can exist relatively stably. At the same time, the nitrogen atoms and oxygen atoms in its structure have lone pairs of electrons, so that 1,3,6-triazine acids can be used as ligands under specific conditions to coordinate with metal ions and other metal ions to form complexes with specific structures and properties, and then show potential application value in many fields such as materials science and catalytic chemistry.
In summary, hydroxyurea and 1,3,6-triazinic acid each have unique chemical properties, which play an important role in chemical research and practical application.

Alas! If you want to make amino-1,3,6-triazine acid, there are various methods. The ancient recipe, although simple and wonderful, should be described today.
First, start with cyanamide. Cyanamide can gradually become the desired acid by the method of hydrolysis. First put cyanamide in the kettle, add an appropriate amount of water, and boil it slowly over a warm fire. The water blends with cyanamide and slowly forms. In the meantime, you need to be careful to check the heat, not too much or too little. When the heat is suitable, the quality of cyanamide will gradually change, and after many steps, you will finally get amino-1,3,6-triazine acid. This way is also like a trickle, which converges in the river and sea, so as to gradually cause work.
The second is based on urea and cyanuric acid. The two are combined in one place, with a catalyst, and in a specific environment, they react in a common phase. Urea and cyanuric acid are ordinary things, but they meet in a suitable place. With the help of a catalyst, they can actually transform into this acid. Like yin and yang sympathetic, it transforms all things. In the meantime, it is essential to control its temperature and pressure. If the temperature is properly pressed, the reaction will be smooth and the product will be pure.
Third, melamine is the beginning. The method of oxidation of melamine can also form this acid. Melamine is placed in a vessel and an oxidant is added to stimulate the reaction in an ingenious way. The process of oxidation is like the burning of gold, which makes the qualitative change of melamine. However, those who do it must understand the degree of oxidation. If it is too much, it will damage its quality, and if it is not enough, it will not work. Careful control can make melamine gradually transform into amino-1,3,6-triazine acid.
All these numbers have their own lengths and difficulties. Those who are skilled should examine their materials, measure their strength, and understand their reasons, and then choose the good and follow them to achieve this delicacy.

In the production process of glutamic acid-1,3,6-trisulfonic acid, there are many precautions.
The first raw material selection must be pure and high-quality. Because of the amount of impurities in the raw material, it is related to the quality of the product. If the raw material is not good, the impurities are mixed into the reaction, or the product is impure, the subsequent separation and purification will also increase the difficulty and consume more material and manpower.
It is crucial to control the reaction conditions. Temperature, pressure, pH, etc. all need to be precisely controlled. If the temperature is too high, the reaction may be too violent, resulting in frequent side reactions and reduced product yield; if the temperature is too low, the reaction will be slow and time-consuming. The same is true for pressure, and the appropriate pressure can ensure the smooth progress of the reaction. The pH affects the reaction rate and balance. A specific reaction requires a specific pH environment. A slight deviation will affect the formation of the product.
The use of catalysts should not be underestimated. High-quality catalysts can accelerate the reaction, improve efficiency, and reduce energy consumption. However, the amount, activity, and lifespan of the catalyst need to be considered. Too much dosage may increase costs; insufficient activity may make it difficult to achieve catalytic effects; short lifespan, frequent replacement is required, which affects the continuity of production.
Reaction equipment is also required. The material must be corrosion-resistant. Due to the reaction process or corrosive substances, if the equipment is not corrosion-resistant, it is easy to damage, shorten the service life, and may cause leakage, endangering production safety. The sealing of the equipment is also critical to prevent the leakage of reactants and products, avoid environmental pollution and personal injury.
The separation and purification steps also need to be cautious. The product is often mixed with impurities and needs to be separated and purified by appropriate methods. The choice of separation technology depends on the characteristics of the product and impurities to ensure that the purity of the product is up to standard. During the operation, the loss of the product should be minimized and the collection rate should be improved.
In the production process, from raw materials to equipment, from reaction conditions to separation and purification, all links are closely linked, and all need to be treated carefully to ensure the smooth production of glutamic acid-1,3,6-trisulfonic acid and obtain high-quality products.
