What are the physicochemical properties of 2,7- (bis (2-arsenic acid phenylazo)) -1,8-dihydroxynaphthalene-3,6-disulfonic acid
2% 2C7-% 28 bis (2-acetaminoacetyl) - 1% 2C8-dimethylnaphthalene - 3% 2C6-disulfonic acid. The physicochemical properties of this substance are as follows:
Looking at its properties, it is mostly in the state of crystalline or powder, or it is slightly different due to the difference in preparation and purity. Its color is usually white to slightly yellow. If it is pure, it is nearly white, and if it contains impurities, it is slightly darker.
The solubility is crucial. It is soluble in water because its sulfonic acid group is hydrophilic and easily interacts with water molecules to form a homogeneous solution. However, in organic solvents, such as common ethanol and ether, the solubility is very small, because its molecular structure is incompatible with the polarity of organic solvents.
In terms of thermal stability, when heated to a certain temperature, the molecular structure may change. In case of high temperature, the sulfonic acid group may be removed, triggering structural rearrangement and decomposition. The specific decomposition temperature varies according to the experimental conditions and purity, and is about a certain temperature range.
The stability of acid and base also has characteristics. In an acidic environment, it is relatively stable. The dissociation degree of the sulfonic acid group may vary due to acid strength, and the overall structure has little effect. However, in a strongly alkaline environment, amide bonds or hydrolysis can damage the molecular structure and cause changes in properties.
