Xiang Jun, 1,2-dioxy-2-imino-has the following properties:
The appearance of this substance is often a specific form, or a crystalline state, or a powder state, depending on its environment and preparation method. Its color is also different, either colorless and transparent, or slightly colored, depending on the synthesis conditions.
When it comes to the melting point, 1,2-dioxy-2-imino-has a specific value. At the melting point, the substance gradually melts from a solid state to a liquid state. This temperature is its inherent property and is related to the force between molecules. At the boiling point, the liquid state changes to the gaseous state, and this process requires the absorption of energy to overcome the attractive forces between molecules.
In terms of solubility, in some organic solvents, it is soluble and evenly dispersed, while in water, the solubility may be different, or slightly soluble, or insoluble, which is closely related to the polarity of the molecule. Those with similar polarities have good mutual solubility and different polarities, and the solubility is poor.
In terms of stability, 1,2-dioxo-2-imino-can maintain a relatively stable state under normal temperature and pressure. In case of high temperature, strong light, or contact with specific chemical substances, their structure or organic changes, and a chemical reaction occurs. This is due to high temperature and strong light providing energy, which greatly increases the activity of molecules, and specific chemical substances meet it, or cause electron transfer, chemical bond breaking and recombination.
Furthermore, its density is also one of the physical properties. Density represents the mass of a substance per unit volume, and this value is related to the mass of the molecule and the way of packing. Compact packed structures tend to have higher density; loose arrangements, lower density.
The physical properties of these are approximate, but in order to know the situation, many experimental investigations and accurate measurements are needed.

Alas! I am inquiring about the chemical properties of 1,2-dicyano- 2-imino-this is a rather professional chemical category. 1,2-dicyano- 2-imino has a certain reactivity. Its cyanyl (-CN) is active and easy to participate in many reactions. In the field of organic synthesis, cyanyl can be converted into carboxyl (-COOH) by hydrolysis. With appropriate conditions and reagents, it can be gradually hydrolyzed to form amides first and then carboxylic acids.
Furthermore, imino (-NH-) also has unique reactivity. Hydrogen of imino has a certain acidity and can react with strong bases to form corresponding salts. And the imino group can participate in the nucleophilic substitution reaction. Because the nitrogen atom has a lone pair of electrons, it can be used as a nucleophilic reagent to attack suitable electrophilic reagents.
And because there are multiple unsaturated bonds in its structure, 1,2-dicyano-2-imino can participate in the addition reaction. For example, the unsaturated bond is added with the nucleophilic test agent to construct a more complex organic structure. And the compound may have a certain conjugation effect, because the existence of the conjugate system may affect its physical and chemical properties, such as increased stability and corresponding changes in the absorption spectrum. < Br >
In addition, in terms of solubility, due to the existence of its polar groups, it may have a certain solubility in polar solvents, but the specific solubility still depends on the type of solvent and the specific structural characteristics of the compound. In short, 1,2-dicyano-2-imino has rich chemical properties and may have various uses and reaction paths in organic synthesis and chemistry research.

"Tiangong Kaiwu" is a masterpiece of ancient science and technology in our country, but it does not contain the synthesis method of "1,2-dicyano-2-amino-group". Due to the limitations of chemical knowledge and technology at that time, such complex organic synthesis is far beyond the scope of the ancients' cognition.
Today's desire for this synthesis method should be found in modern organic chemistry classics. Such synthesis often involves multi-step reactions, requiring fine operation and professional knowledge.
At the beginning, a halogen atom may be introduced through a halogenation reaction with a suitable starting material, and this halogen atom is the active check point of the subsequent reaction. Then, through the cyanidation reaction, the halogen atom is replaced by a cyanide group to obtain a cyanide-containing intermediate. < Br >
Then with an appropriate reducing agent, the cyanyl group is partially reduced to an amino group. This step requires precise control of the reaction conditions to prevent excessive reduction or other side reactions.
During the synthesis process, the choice of solvent, temperature and catalyst is crucial, which all affect the reaction rate and product purity. And after each step of the reaction, it is often necessary to separate and purify to obtain high-purity products.
This is only a general idea. The actual synthesis needs to be explored and optimized according to the specific starting materials and reaction conditions, and many experiments can be used to obtain a feasible synthesis method.
