The main use of benzoyl hydrazide is in the field of insect growth regulators. Its role is particularly critical, which can simulate the ecdysone in insects and interfere with the normal growth and development process of insects.
Look at the growth of pests, each through the stages of eggs, larvae, pupae and adults. Benzoyl hydrazide is applied to the environment where pests are located. After the larvae eat or come into contact with this agent, because its structure is similar to ecdysone, it will cause insects to molt prematurely or abnormally. Under normal circumstances, the molting of insects proceeds in an orderly manner, and a new epidermis is formed and hardened, and then the growth transformation is completed. However, due to the influence of benzoyl hydrazide, the molting process is disordered, the new epidermis cannot form or develop normally, and the larvae may not be able to molt smoothly, causing the body to be trapped in the old epidermis and eventually die; or although the skin is barely molted, the newly formed individual is deformed and cannot eat, move and reproduce normally, resulting in a gradual decrease in the population.
This agent is widely used in many fields such as agriculture, forestry and horticulture. In agriculture, it can effectively control lepidoptera pests such as cotton bollworm and cabbage green insect. These pests often cause serious damage to crops. The application of benzoyl hydrazide helps farmers ensure crop yield and quality. In forestry, it can prevent and control pests such as pine caterpillars and protect forest ecology. In terms of horticulture, it can protect flowers and green plants from pests, make them flourish, and maintain the beauty of the landscape. It is selective and has low toxicity to beneficial insects and mammals. Compared with traditional highly toxic pesticides, it is more in line with the concept of green environmental protection, and plays an important role in the comprehensive management system of modern pests.

Dibenzyl ketone is one of the organic compounds. Its physical properties are quite specific, and this is for you to describe in detail.
Looking at its appearance, under room temperature and pressure, dibenzyl ketone is often white to light yellow crystalline powder, delicate and with a certain luster, like the fine snow falling at the beginning of winter, and like the dust flickering in the morning light. Under the sunlight, it glows faintly.
When it comes to the melting point of this substance, the melting point of this substance is about 34-38 ° C. When the temperature gradually rises, the originally solid crystals are like thin ice in spring, slowly melting into a flowing liquid, just like ice and snow melting when they are warm, showing its soft and changeable state.
As for the boiling point, it is about 344 ° C. At such a high temperature, the liquid dibenzyl ketone will turn into a curling vapor, rising in the air, like a cloud, disappearing and invisible. This is the wonderful change from liquid to gaseous.
In terms of solubility, dibenzyl ketone can be soluble in many organic solvents. In ethanol, like a fish in water, it quickly diffuses and dissolves, making the solution appear uniform and transparent; in ether, it can also be fused with it, and the two are closely combined, regardless of each other. However, its solubility in water is very small, just like oil floats in water, making it difficult to blend. This is because the molecular structure of dibenzyl ketone is quite different from that of water.
Furthermore, dibenzyl ketone has a certain density, about 1.095 g/cm ³. This density value indicates that it is slightly heavier than water. If it is placed in water, it will slowly sink, like a stone falling into a deep pool and gradually sinking to the bottom.
In addition, its unique smell, slightly fragrant, is not like the rich floral fragrance of roses and jasmine, but an elegant fragrance, just like the deep mountain orchid, which inadvertently emits strands of aroma, giving people a sense of freshness.
In summary, the physical properties of dibenzylmethyl ketone are diverse, including appearance, melting point, boiling point, solubility, density, and odor, all of which are unique and together constitute the characteristics of this substance.

Diethylene glycol amine, its chemical properties are quite stable. Diethylene glycol amine is an organic compound with nitrogen atoms and hydroxyl groups, which give it many unique properties.
In terms of structure, its molecular structure is relatively regular, which makes it stable to a certain extent. In terms of chemical activity, although the lone pair electrons on its nitrogen atom have certain reactivity, due to the steric resistance of surrounding groups and the influence of electronic effects, the overall reactivity is not very high, and it will not easily undergo violent chemical reactions.
Under common environmental conditions, diethylene glycol amine can maintain its own structural integrity. At room temperature and pressure, it is difficult to spontaneously react significantly with common components in the air, such as oxygen and carbon dioxide, and can exist relatively stably in the air.
In general organic solvents, diethylene glycol amine can also maintain good stability and will not easily chemically react with solvents to cause damage to its own structure. Moreover, it also has a certain tolerance to heat, and under moderate heating conditions, it will not decompose rapidly or undergo chemical changes, but if the temperature is too high, beyond its tolerance range, it will also cause reactions such as decomposition.
From a storage perspective, as long as diethylene glycol amine is stored in a dry, cool and well-ventilated place, avoiding contact with strong oxidants, strong acids, strong bases and other substances with strong reactivity, its chemical properties can be maintained for a long time for future industrial or scientific research purposes.

For dimercaptoethanol, it is also a colourless liquid with a foul odor. During storage and transportation, many matters must be paid attention to.
First storage environment. Choose a cool and ventilated warehouse, away from fires and heat sources. This is because dimercaptoethanol is flammable, and there is a risk of combustion and explosion in case of open flame and high heat energy. The warehouse temperature should be controlled below 37 ° C, and the container should be kept sealed to prevent it from evaporating and escaping. And it should be stored separately from oxidants, acids, alkali metals, etc., and should not be stored in mixed storage. Because dimercaptoethanol encounters with various chemicals, or reacts violently, causing danger.
Second and packaging requirements. The packaging must be tight and sealed to ensure that there is no risk of leakage during transportation. The packaging materials used shall have good corrosion resistance and sealing. On the outside of the packaging, it is necessary to clearly label the chemical identification, hazard characteristics, emergency disposal methods and other information, so that the transporter and related personnel can understand the danger.
When transporting, there are also many key points. The transportation vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. It is recommended to transport in the morning and evening in summer to avoid high temperature periods to prevent it from evaporating due to excessive temperature or causing danger. During transportation, ensure that the container does not leak, collapse, fall, or damage. And the speed should not be too fast, and the package should not be forcibly overtaken to prevent the package from being damaged due to bumps and collisions. When transporting by road, follow the prescribed route and do not stop in residential areas and densely populated areas. When transporting by rail, it is strictly forbidden to slip.
All of these are the key to the storage and transportation of dimercaptoethanol, and practitioners need to follow them carefully to ensure safety.

Benzophenone is also an organic compound. It has various effects on the environment and human health.
Looking at its impact on the environment, benzophenone has a certain persistence. It often exists in the environment and is not easy to degrade. For example, in water bodies, although the amount is small, it will increase over time, which can cause changes in water quality. And it also has potential harm to aquatic organisms. After research, benzophenone can cause the growth and reproduction of some aquatic organisms to be hindered. If young fish are exposed to water bodies containing benzophenone, their growth rate may slow down, and even their behavior is different from normal, affecting their viability in the natural environment. In the soil, benzophenone may affect the community structure and function of soil microorganisms, which in turn is detrimental to the material cycle and energy conversion of the soil ecosystem.
As for the impact on human health, benzophenone may have a latent risk. Because it is fat-soluble, it is easily absorbed by the body through the skin. Studies have shown that long-term exposure to benzophenone may interfere with the human endocrine system. The endocrine system is related to human growth, development, metabolism and many other important physiological processes. If endocrine is disturbed, it may cause hormone imbalance. For example, it may affect the secretion and regulation of thyroid hormones, which in turn affects the human body's metabolic rate, causing body weight fluctuations, fatigue and other symptoms. And benzophenone may have certain allergenicity. Some people come into contact with products containing this substance, such as certain cosmetics, or cause allergic reactions to the skin, causing redness, swelling, itching, etc., which affects the quality of life.
In summary, benzophenone has an impact on the environment and human health that cannot be ignored. It should be treated with caution to ensure the safety of the environment and personal health.
