Pyridine, 3-(diethylboryl)-

(Diacetamide) The chemical properties of this substance are particularly important. Among this substance, the structure of the diacetamide group gives it unique properties.
It has a certain stability. Due to the conjugation effect of the carbonyl group and the nitrogen atom in the amide structure, the molecular energy is reduced and the structure is stabilized. However, under certain conditions, it will also show an active state.
In a strongly acidic environment, amide bonds can be hydrolyzed. This hydrolysis process is like the erosion of a dam by water, gradually breaking the amide bond. The proton first binds to the carbonyl oxygen atom, which enhances the positive electricity of the carbonyl carbon. Then water molecules attack the carbon, and through a series of transformations, the amide bond is finally broken, resulting in the formation of corresponding carboxylic acids and amines.
In alkaline environments, amides also hydrolyze, but the mechanism is slightly different from acidic hydrolysis. Hydroxide ions attack carbonyl carbons first, and subsequent reaction steps lead to the breakdown of amide bonds, resulting in carboxylic salts and amines.
Diacetyl amines also have a certain solubility. Because they contain polar amide groups, they have a certain solubility in polar solvents such as water. Amide groups can form hydrogen bonds with water molecules, and the force of this hydrogen bond prompts the substance to dissolve in water. However, its alkyl group has a certain degree of hydrophobicity, which makes its solubility non-infinite.
In addition, the diacetyl amine structure can participate in many organic reactions. For example, it can be substituted with other compounds containing active groups under the action of appropriate catalysts, so as to modify and modify the molecular structure and expand its use in different fields.
The chemical properties of this (diacetyl amine) substance are rich and diverse, and it plays an important role in many fields such as organic synthesis and medicinal chemistry. In-depth investigation of its properties can provide strong support for the development of related fields.

Dithiocyanomethane has the following main uses:
First, in the agricultural field, it can be used as a soil disinfectant. Because of its high-efficiency and broad-spectrum bactericidal properties, it can effectively kill a variety of pathogens such as Fusarium, Rhizoctonia, and Pyloromyces in the soil, thereby significantly reducing the probability of soil-borne diseases in crops and improving crop yield and quality. For example, in the past, farmers used to treat the soil with dithiocyanomethane before sowing to ensure that seedlings thrive and are protected from diseases.
Second, in industrial circulating water systems, it can be used as a biocide. Long-term operation of industrial circulating water makes it easy to breed bacteria, algae and other microorganisms, which can cause corrosion and blockage to pipelines and affect the normal operation of the system. Dithiocyanomethane can quickly inhibit and kill such microorganisms, ensuring the smooth operation of the circulating water system, just like building a barrier against microbial invasion for the industrial circulating water system.
Third, in the paper industry, it also has important uses. In the pulp production process, it is susceptible to microbial contamination, resulting in pulp deterioration, paper spots and other problems. Dithiocyanomethane can effectively inhibit the growth of microorganisms in pulp, ensure the quality of pulp, and make the paper white, tough and flawless.
Fourth, in the field of oil field water injection, it can be used as a fungicide. If the oil field water injection contains a large number of microorganisms, it will corrode the downhole equipment, and may also block the oil reservoir, affecting the oil recovery efficiency. Dithiocyanomethane injected into water can kill microorganisms, maintain the stability of the oilfield water injection system, and help the smooth development of oil exploration.

The synthesis of dithiocarbonyl groups is described in ancient books such as Tiangong Kaiwu, and there are many methods, each with its own advantages.
One is the direct combination of sulfur and carbonyl-containing compounds. Choose pure sulfur, and suitable carbonyl compounds, such as aldose and ketone, in a specific reaction vessel, under suitable temperature and pressure, to catalyze. For example, using an aldehyde and sulfur as raw materials, in a closed kettle, the temperature is controlled at hundreds of degrees, and a catalyst is used to combine the two to produce a product of disulfuryl carbonyl. In this process, the temperature and the amount of catalyst need to be precisely controlled, otherwise the yield and product purity will be affected.
The second is obtained by substitution reaction. React with a carbonyl compound containing a halogen atom with a sulfur reagent. For example, choose a ketone containing chlorine, and a sulfur reagent such as sodium sulfide, in an alcohol solvent, heat and stir. The chlorine atom is replaced by a sulfur atom to form a disulfide carbonyl structure. During the reaction, the properties of the solvent, the ratio of the reactants and the reaction time are all related to the effectiveness of the reaction. The polarity and solubility of the alcohol solvent can promote the contact and reaction of the reactants; the appropriate ratio can make the reaction sufficient and avoid waste of raw materials; the appropriate reaction time can ensure the completion of the reaction without overreacting to produce by-products.
The third is the synthesis using organometallic reagents. First prepare metal reagents such as organolithium or organomagnesium, and then react with carbonyl derivatives containing sulfur. This method has high activity of organometallic reagents, good reactivity and selectivity. However, it requires strict reaction conditions and needs to be operated in an anhydrous and oxygen-free environment to prevent the inactivation of organometallic reagents. If an organolithium reagent is prepared, it can be efficiently synthesized with a specific thiocarbonyl compound under low temperature and nitrogen protection. The entire operation process needs to be cautious, and the specifications of anhydrous and oxygen-free must be strictly followed from the preparation of the reagent to the progress of the reaction.

Second, in the process of storage, pay attention to the situation in general, and consider it carefully.
It is appropriate to store it in the first place. It is advisable to keep it in a place where things are dry and clear, and avoid the atmosphere of the tide. The tide is easy to cause it to rot and grow, and the atmosphere gathers or causes it to grow. And the degree is also properly controlled, and the height or low may affect its performance. If it is in a high-pressure place, it is feared that its parts will be damaged; if it is in a low-pressure environment, it may cause its materials to brittle and solidify.
And its stacking method should not be ignored. It is neat and orderly, and it should not be piled up. To prevent collision and friction with each other, the outside of it will be damaged, and even the part of the system will be broken. And do not pile up heavy loads, lest its bearing capacity be low, and it will cause damage.
When it is difficult to see, the package must be broken. Wrap it with soft and solid materials, such as thick cloth and hard wooden boxes, to prevent shocks and collisions on the way. If it is difficult to see, it is also easy to travel on the road, to avoid urgent and severe bumps. Stop on the way, and it is advisable to send people to guard it in a safe place to prevent it.
And the journey of storage is difficult to see. Where and where to exist, and how to do it, are all clear one by one. If there is any problem, it is necessary to trace the source and locate it. In this way, the two can be guaranteed. The journey of storage is safe and safe, and it can be used for a long time.

At present, in the market, the price of diethanolamine varies roughly depending on changes in market conditions. Its price is often determined by various factors such as the supply of raw materials, the demand for demand, and political regulations.
In the past, if the production of raw materials was abundant and the supply exceeded the demand, the price might stabilize and decrease slightly. On the contrary, if the raw materials were scarce, the supply would not be sufficient, and the price would rise.
Moreover, the demand of the market is also a major factor. When the industry is prosperous, the demand for diethanolamine will be high; if the industry is sluggish and the demand decreases, the price will also follow.
According to recent market conditions, the price of diethanolamine is between [X] yuan and [X] yuan per ton. However, this is only a rough figure, the market is changeable, and the actual price may fluctuate. When merchants trade, they can get a suitable price when they carefully observe the dynamics of the market, the situation of raw materials, and the trend of the industry. The market is changing rapidly. Only those who are sensitive to observation and good at judgment can move freely in the business road and obtain the benefits they seek.
