What are the Physical Properties of 7-Hydroxy-8- ((4- (Phenylazo) Phenyl) Azo) Naphthalene-1,3-Disulphonic Acid, Compounded With Dicyclohexylamine
A compound of 7-hydroxy-8- ((4- (phenylazo) phenyl) azo) naphthalene-1,3-disulfonic acid and dicyclohexylamine. Its physical properties are as follows:
This compound is often powdered in a specific color, and its color is derived from the complex azo structure in the molecule. The powder is fine in texture and feels smooth to the touch.
In terms of solubility, the degree of solubility in water is limited, because the molecule contains both polar sulfonic acid groups and non-polar aromatic rings and dicyclohexylamine parts. The interaction between the polar and non-polar parts results in poor solubility in polar solvent water. However, in some organic solvents such as ethanol and acetone, the dissolution state is relatively good, and the polarity of the organic solvent is adapted to the molecular structure, which helps the molecules to disperse.
Melting point is also one of its important physical properties. The specific melting point value can be obtained after measurement, which reflects the strength of the intermolecular force. Various interactions such as intramolecular hydrogen bonds, interaromatic ring π-π stacking, and ionic bonds (if present) together determine the melting point. The exact value of the melting point of this compound is of great significance for the study of its stability and phase changes at different temperatures.
In addition, the density of this compound is moderate, depending on the type, number, and spatial arrangement of the atoms in the molecule. The density is related to its behavior characteristics such as sedimentation and dispersion in different media. In practical application scenarios, such as preparing specific materials or participating in chemical reaction systems, the density characteristics will affect the physical processes such as mass transfer and heat transfer in the reaction process.

To prepare a compound of 7-hydroxy-8- ((4- (phenylazo) phenyl) azo) naphthalene-1,3-disulfonic acid and dicyclohexylamine, the method is as follows:
First take an appropriate amount of naphthalene-based compounds, and introduce sulfonic acid groups under specific conditions to obtain naphthalene intermediates containing sulfonic acid groups. When sulfonating, the reaction temperature, time and amount of sulfonating reagents should be carefully controlled to ensure that the sulfonic acid groups are accurately introduced into the 1,3 positions of the naphthalene ring to conform to the expected structure.
Then, the azo reaction is carried out. The obtained intermediate is reacted with azo reagents such as sodium nitrite in a suitable acidic medium to generate diazo salts. This step of the reaction is very critical to the control of the pH value and temperature of the reaction system, and must be precisely adjusted to ensure the stable formation of diazo salts and avoid side reactions.
Then couple with an aromatic amine compound containing phenyl azo. In the presence of an appropriate buffer system and catalyst, the diazo salt is coupled to the aromatic amine, and the (4- (phenyl azo) phenyl) azo) structure is introduced at the 8th position of the naphthalene ring to obtain 7-hydroxy-8- (4- (phenyl azo) phenyl) azo) naphthalene-1,3-disulfonic acid.
Finally, make 7-hydroxy-8- ((4- (phenylazo) phenyl) azo) naphthalene-1,3-disulfonic acid and dicyclohexylamine in an appropriate ratio, react in a suitable solvent, stir, crystallize, etc., to obtain 7-hydroxy-8- (4- (phenylazo) phenyl) azo) naphthalene-1,3-disulfonic acid and dicyclohexylamine compound. Throughout the reaction, each step requires strict control of conditions and careful operation to achieve ideal yield and purity.
