Ferric 4-borylbenzoate is a chemical substance with unique characteristics. Its physical properties are quite unique, let me tell you one by one.
The first to bear the brunt is its appearance. Ferric 4-borylbenzoate is often powdery, with a white color like snow, just like the frost that falls at the beginning of winter, delicate and pure, giving people a sense of simplicity.
When it comes to solubility, this substance has a low solubility in water, like a stone hidden in the bottom of the water, and is difficult to dissipate easily. However, if placed in some organic solvents, such as ethanol and acetone, it can show good solubility, just like fish entering water, leisurely, and can be integrated with organic solvents.
Furthermore, the melting point of ferric 4-borylbenzoate is also one of its important physical properties. Its melting point is relatively high, and a higher temperature is required to transform it from a solid state to a liquid state, just like a stubborn stone that needs to be calcined before it can be converted into a fluid. This characteristic allows the substance to maintain a stable solid structure at room temperature and is not prone to morphological changes.
In addition, the density of the substance cannot be ignored. Its density is moderate, neither as light as a feather nor as heavy as Mount Tai. In practical applications, this characteristic helps it to be reasonably distributed in different systems and play its due role.
In terms of stability, ferric 4-borylbenzoate is quite stable under normal conditions, like a strong fortress, and it is not easy to chemically react with the surrounding environment. However, it should be noted that in case of extreme chemical environments such as strong acids and bases, its stability will be challenged, just like a fortress encountering a strong enemy, and structural changes or chemical reactions may occur.
Overall, the many physical properties of ferric 4-borylbenzoate determine its unique application value in many fields such as chemistry and materials. It is a substance worthy of in-depth study and exploration.

Alum is an aqueous crystallization of a class of metal sulfates. Lead alum, that is, lead sulfate ($PbSO_ {4} $), is a white monoclinic or orthogonal crystal with many chemical properties.
The chemical properties of lead alum are as follows:
First, it is stable. Under normal temperature and pressure and dry environment, lead alum can exist stably and does not react significantly with common substances in the air, such as oxygen, nitrogen, carbon dioxide, etc.
Second, it reacts with acids. Lead alum is insoluble in water, but can react with strong acids. In case of concentrated sulfuric acid, lead bisulfate will be formed: $PbSO_ {4} + H_ {2} SO_ {4} (concentrated) \ longrightarrow Pb (HSO_ {4}) _ {2} $. In case of nitric acid, due to the strong oxidizing and acidic nature of nitric acid, although lead alum is insoluble, in the nitric acid environment, some lead ions will dissolve a small amount due to the influence of nitric acid on its dissolution balance, but this reaction is relatively weak.
Third, the reaction with alkali. Lead alum can slowly react with strong alkali solutions to form lead salts. For example, when reacted with sodium hydroxide solution, sodium leadite will be formed: $PbSO_ {4} + 4NaOH\ longrightarrow Na_ {2} PbO_ {2} + Na_ {2} SO_ {4} + 2H_ {2} O $.
Fourth, thermal stability. When heated, lead alum will gradually lose its crystal water and decompose when the temperature rises further. At about 1170 dollars ^ {\ circ} C $, lead sulfate will decompose into lead oxide, sulfur dioxide and oxygen: $2PbSO_ {4}\ stackrel {1170 ^ {\ circ} C }{=\!=\!=} 2 Pb O + 2SO_ {2}\ uparrow + O_ {2}\ uparrow $.
Fifth, the reaction with some salt solutions. When lead alum meets a soluble barium salt solution, because the solubility of barium sulfate is much smaller than that of lead sulfate, a precipitation transformation reaction will occur to form barium sulfate precipitation. Such as reacting with barium chloride solution: $PbSO_ {4} + BaCl_ {2}\ longrightarrow BaSO_ {4}\ downarrow + PbCl_ {2} $.
These chemical properties of lead alum are reflected in ancient alchemy, metallurgy and medicine. Although the ancients did not understand its exact chemical principle, they used its characteristics in practice to achieve specific purposes.

If you want to make sodium borohydride, there are all kinds of things. Sodium borohydride has a wide range of uses and is used in the chemical and pharmaceutical industries. There are the following common methods for its preparation.
First, the method of co-heating sodium hydride and trimethyl borate. Make sodium hydride and trimethyl borate interact under appropriate temperature and pressure. Prepare sodium hydride first, which has high activity and must be properly disposed of. Take trimethyl borate and mix the two in an appropriate ratio. Place it in a special reactor and slowly heat up to maintain a certain pressure and temperature range. In this process, the hydrogen of sodium hydride is combined with the boron of trimethyl borate to produce sodium borohydride and trimethoxy boron. The reaction formula is roughly as follows:\ (4NaH + B (OCH_ {3}) _ {3}\ stackrel {\ Delta} {\ longrightarrow} NaBH_ {4} + 3NaOCH_ {3}\). This reaction requires fine temperature and pressure control, and the quality of sodium hydride and trimethyl borate also affects the product.
Second, the method of double decomposition of potassium borohydride and sodium salt. First obtain potassium borohydride, which can be prepared by the corresponding method. Then take sodium salts, such as sodium chloride, etc. React potassium borohydride and sodium salt in a suitable solvent. The potassium ions in potassium borohydride and the sodium ions in the sodium salt are exchanged with each other, and sodium borohydride is obtained. The choice of this reaction solvent is quite critical, so that both potassium borohydride and sodium salt can be moderately dissolved without reacting with the product sodium borohydride. For example, alcohol is used as a solvent and the reaction is stirred at a specific temperature. The reaction mechanism lies in the exchange of ions, but the reaction rate and product purity are determined by many factors such as solvent, temperature, and the concentration of the reactants.
Third, the method of direct reaction of boron, hydrogen, and sodium metal is used. Boron powder and sodium metal are mixed in a certain proportion and hydrogen is introduced. Under high temperature and high pressure conditions, boron is combined with hydrogen and sodium metal. Boron and hydrogen first form an intermediate of borohydride, and then further react with sodium metal to obtain sodium borohydride. This process requires strict requirements for the reaction equipment, and the high temperature and high pressure environment requires special materials and safety measures. The purity of boron powder, hydrogen, and sodium metal is also related to the smooth reaction and the quality of the product.
All production methods have their own advantages and disadvantages. In actual preparation, it is necessary to choose carefully according to the purity, cost, scale and other factors of the desired product.

Strontium 4-nitroformate is an important chemical substance. When storing and transporting it, many key precautions must be taken with care.
