How stable is diphenylguanidine hydrobromide?
The stability of dibenzoyl hydrazide carbonate is related to many things. The stability of this substance is first determined by its structure. In its molecular structure, the characteristics of chemical bonds are crucial. The benzene ring structure has high stability, and its conjugated system can disperse the electron cloud, reducing the molecular energy, thus contributing to the overall stability. The part of dibenzoyl hydrazide is connected to the carbonate, and the strength and properties of the chemical bonds during it also affect its stability.
Furthermore, external environmental factors have a great influence on its stability. Temperature changes are often critical. If the temperature is too high, the thermal motion of the molecule intensifies, and the vibration of the chemical bond increases. When it reaches a certain extent, the chemical bond may break, causing its stability to be damaged. Therefore, the preservation of this substance should be controlled in a suitable low temperature environment.
Humidity should not be underestimated. The presence of moisture in the environment may trigger a hydrolysis reaction. Water molecules can interact with dibenzoyl hydrazide carbonate molecules, causing hydrolysis and fracture of carbonate bonds, resulting in corresponding acids and alcohols and other products, which seriously damage its stability. Therefore, it is necessary to ensure that the environment is dry when storing.
Light is also an influential factor. Light of a specific wavelength, or containing enough energy, causes electron transitions in molecules, triggering photochemical reactions and affecting its stability. Store away from direct light and choose a place away from light.
In addition, the mixing of impurities, or catalyzing certain chemical reactions, accelerates its decomposition, which is unfavorable to stability. In the preparation and storage process, it is necessary to strictly control the purity and avoid the introduction of impurities.
In summary, in order to maintain the stability of dibenzoyl hydrazide carbonate, it is necessary to consider its own structural characteristics, and carefully control the external temperature, humidity, light and other conditions, and strictly control the purity.

Do not act recklessly because of your ability, and cause the sick to be in danger.
Is the production process of diphenylguanidine hydrobromide complicated?
The production process of benzophenone hydrazone hydrochloride has not been recorded in the various techniques involved in "Tiangong Kaiwu". "Tiangong Kaiwu" was written in Chongzhen for ten years in the Ming Dynasty, and it detailed various technologies of agriculture and handicraft industry. However, the method of chemical synthesis has not yet been realized at that time.
The production of benzophenone hydrazone hydrochloride belongs to the field of organic synthesis. The method involves a multi-step reaction, starting with benzophenone and condensing with hydrazine hydrate to obtain benzophenone hydrazone. This step requires controlling the reaction temperature, time and the ratio of reactants to promote the reaction in the direction of generating benzophenone hydrazone, or using a catalyst to increase the reaction rate. After obtaining benzophenone hydrazone, it reacts with hydrochloric acid to form benzophenone hydrazone hydrochloride. This process also requires precise regulation of reaction conditions, such as temperature, pH, etc., to ensure product purity and yield.
This production process requires multi-disciplinary knowledge of organic chemistry, chemical principles, etc. From raw material preparation, reaction operation to product purification, all links need to be carefully controlled. Raw material purity, reaction equipment material and design, reaction process monitoring and regulation all affect product quality. Compared with the traditional process contained in "Tiangong Kaiwu", its theoretical basis, operation mode and technical requirements are very different. " "Tiangong Kaiwu" is mostly concerned with the processing and utilization of natural materials, based on experience summary; while the production of benzophenone hydrazone hydrochloride is based on modern chemical theory, advanced analytical testing methods and automated equipment, in order to achieve the purpose of precise control and efficient production.
What is the price range of diphenylguanidine hydrobromide in the market?
In today's market, the price of benzophenone hydrazone often varies depending on the quality and the supply and demand of the market. Looking at various markets, the price is about tens of yuan to hundreds of yuan per kilogram.
If the quality is good, when the supply is less than the demand, the price may increase, up to two or three hundred yuan per kilogram, or even higher. Because of its good quality, it is suitable for high-end domains, and users compete for purchases, causing prices to rise.
However, if the quality is average and the supply exceeds the demand, the price will decrease, or only a few tens of yuan per kilogram. This is because the quality is not high, the substitutability is strong, and the market demand is limited, so the price is difficult to be high.
The market conditions are changing rapidly. From time to time, the price of raw materials rises, resulting in an increase in production costs, and the price of benzophenone hydrazone also rises; from time to time, new technologies are introduced, production capacity increases, supply increases and prices fall. And the price varies depending on the region. Prosperous commercial ports, convenient logistics, smooth supply and demand, prices may change from time to time; remote places, due to transportation costs, supply and demand constraints, prices may be different from those in Tongdu Dayi.
Therefore, if you want to know the exact price of benzophenone hydrazone, you must carefully observe the status, quality, and various factors that affect it.
