What are the physical properties of'Barium Bis {2- [ (2Z) -2- (2-Oxonaphthalen-1 (2H) -Ylidene) Hydrazinyl] Naphthalene-1-Sulfonate '?
"Barium bis {2- [ (2Z) -2 - (2-oxynaphthalene-1 (2H) -subunit) hydrazine] naphthalene-1-sulfonate}" The physical properties of this substance are as follows:
From the perspective, it often takes a specific form, or is in the shape of powder, and the color is mostly plain, or white as snow, or nearly colorless and transparent, fine and uniform. When touched, it feels delicate, and it seems to be slippery at the tip of the finger.
In terms of solubility, in the solvent of water, its dissolution state is quite critical. At room temperature, the degree of dissolution in water is limited, only a little soluble, and the solution is slightly thin. However, if the temperature is raised to a specific degree, the amount of dissolution can gradually increase, and the color of the solution will also become slightly darker, but its essence has not changed, and it is still a uniform dispersion system.
When it comes to density, it is heavier than ordinary water. When placed in a liquid, it can sink to the bottom. The value of its density, according to accurate measurement, is [X] grams per cubic centimeter. This value can vary slightly according to the preparation method and purity.
Thermal stability is also an important property. When heated, when the temperature rises to a specific value, about [X] ° C, its structure begins to change and its chemical properties also change. At first, there may be subtle changes, shape or slight changes, and then the tendency to decompose gradually appears, forming other substances. This process is often accompanied by changes in color and gas escape.
In addition, its conductivity varies from different states. In the solid state, there is little ability to conduct electricity; however, if it dissolves in water and forms an ionic state, it can conduct a weak current, because there are movable ions in the solution, which can conduct electrical charges.
What is the production method of'Barium Bis {2- [ (2Z) -2- (2-Oxonaphthalen-1 (2H) -Ylidene) Hydrazinyl] Naphthalene-1-Sulfonate '?
To prepare "Barium Bis {2- [ (2Z) -2- (2-Oxonaphthalen-1 (2H) -Ylidene) Hydrazinyl] Naphthalene-1-Sulfonate}", the method is as follows:
Take an appropriate amount of 2-naphthol first, place it in a clean reactor, use alcohol as a solvent, add an appropriate amount of alkali, and dissolve it. After stirring evenly, slowly add sodium nitrite, and strictly control the temperature within a specific range, so that the two can fully react to generate diazonium salts. This process requires close attention to the reaction process and temperature changes to prevent side reactions from occurring.
Take another 2-hydroxy-1-naphthalaldehyde, place it in another reaction vessel, also dissolve it in a suitable solvent, and then add the diazonium salt solution obtained above dropwise under stirring. During the reaction, the pH of the solution is continuously monitored and adjusted in a timely manner to ensure that the reaction proceeds in the desired direction, resulting in the generation of 2- [ (2Z) -2- (2-Oxonaphthalen-1 (2H) -Ylidene) Hydrazinyl] Naphthalene-1 - Sulfonic Acid intermediate.
Subsequently, this intermediate is moved into a new reaction vessel and a barium salt solution, such as barium chloride or barium nitrate solution, is added. Under appropriate temperature and stirring conditions, the intermediate is fully reacted with the barium salt, and a metathesis reaction occurs. The barium ion is combined with the sulfonate ion, and finally "Barium Bis {2- [ (2Z) -2- (2 - Oxonaphthalen - 1 (2H) -Ylidene) Hydrazinyl] Naphthalene - 1 - Sulfonate}" is formed. After the reaction is completed, a pure product can be obtained through various steps such as cooling, filtration, washing, and drying. The whole preparation process requires fine control of each reaction condition to ensure the purity and yield of the product.
