What are the physical properties of Chromium (3 +) tri (2-pyridinecarboxylate)?
Chromium (ⅲ) tri (2 -pyridinecarboxylate), that is, tris (2 -pyridinecarboxylate) chromium (ⅲ), the physical properties of this substance are as follows:
Its appearance is often a solid of a specific color, the specific color varies slightly due to preparation conditions and purity, or it is a dark powder, or a solid with a specific crystal form. The melting point of this compound is quite high, because the internal chemical bond energy is stable with the lattice structure, a higher temperature is required to cause its lattice disintegration and material melting.
In terms of solubility, in common organic solvents such as ethanol and ether, its degree of solubility is limited, showing insoluble characteristics. However, in some specific polar solvents, or due to the formation of specific interactions between the solvent and the solute, such as hydrogen bonds, coordination, etc., it exhibits a certain solubility.
Its density is higher than that of common organic compounds. Due to the relatively large atomic mass of chromium, and the compact structure of the compound, the mass per unit volume increases.
In addition, the compound has certain stability to light and heat under specific conditions. In a light environment, if the light energy does not reach the level of exciting its internal electron transition or breaking chemical bonds, the structure can be maintained stable. When heated, the structure and properties remain relatively stable in the temperature range below the melting point. If the temperature is too high to approach or reach the melting point, a phase transition occurs. At the same time, its crystal structure endows it with certain mechanical properties, and it has certain hardness and brittleness in the solid state.
What is the synthesis method for Chromium (3 +) tri (2-pyridinecarboxylate)?
To prepare Chromium (III) tri (2 - pyridinecarboxylate), the following method can be followed.
Prepare all the ingredients first, including a trivalent chromium salt, such as chromium sulfate ($Cr_2 (SO_4) _3 $) or chromium chloride ($CrCl_3 $), and 2 - pyridinecarboxylate ($C_6H_5NO_2 $). These two are the main ingredients for preparing the substance.
In a clean container, hold an appropriate amount of water as the reaction medium. Slowly add the prepared trivalent chromium salt, stir it, and dissolve the salt into the water to form a uniform solution. In this process, it is necessary to pay attention to the dissolution of the salt. If it is not easy to dissolve, it can be heated slightly, but the temperature should not be too high to prevent subsequent reactions.
When the chromium salt is completely dissolved, add 2-pyridinecarboxylate to this solution slowly. When adding, slowly do it and keep stirring to ensure that the two are fully mixed. 2-pyridinecarboxylate will react with chromium ions to gradually generate Chromium (III) tri (2-pyridinecarboxylate).
When reacting, the pH value can be adjusted according to the reaction status. Because the appropriate pH value helps the reaction to proceed in the direction of generating the target product. In general, by adding an appropriate amount of alkali, such as sodium hydroxide ($NaOH $) solution, the pH value of the system can be maintained within a certain range. This range may be determined by previous exploratory experiments, which are roughly in the weakly alkaline range.
After the reaction is completed, a mixed solution containing Chromium (III) tri (2 - pyridinecarboxylate) can be obtained. At this time, to obtain a pure product, a filtration method can be used to filter out insoluble impurities in the solution. Next, the filtrate is recrystallized with an appropriate solvent. When selecting a solvent, the solubility characteristics of the product in the solvent should be considered. For example, a mixed solvent of ethanol and water can be selected. After repeated recrystallization, the purity of the product can be improved, resulting in a relatively pure Chromium (III) tri (2 - pyridinecarboxylate).
