3% 2C4, that is, arsenic trioxide, commonly known as arsenic, highly toxic. Its main uses are as follows:
In the medical field, although it is a highly toxic substance, it can be used to treat specific diseases after scientific refining and strict control. For example, in the treatment of leukemia, arsenic trioxide can induce leukemia cell apoptosis, and has a significant effect on acute promyelocytic leukemia, bringing vitality to many patients. There are also relevant medicinal records in the Compendium of Materia Medica. The ancients have explored its medicinal value.
In industry, it can be used as a clarifying agent for making glass. When melting glass, it can effectively remove bubbles in the glass liquid, making the glass more uniform and transparent, and improving the quality of the glass. At the same time, in some non-ferrous metal smelting, it can be used as an additive to improve metal properties and improve smelting efficiency.
In the agricultural field, it has been used as an insecticide in the past to control some pests. However, due to its strong toxicity, it is easy to cause harm to the environment and organisms, and its use is now strictly limited.
However, it is necessary to keep in mind that arsenic trioxide is highly toxic, and its use and operation must follow strict regulations and safety procedures to prevent poisoning accidents. Although it has certain uses, it should not be abused at will, so as not to endanger life, health and the ecological environment.

To make trichlorotetrahydroxy dioxypentaisonitrile tricarboxylic acid, the method is as follows:
Prepare all the required materials first, select high-quality raw materials, whether they are pure or not, it is related to the quality of the product. Then, in a clean vessel, put the raw materials in a certain order. First take an appropriate amount of specific starting materials, which need to be carefully measured, the difference is exact, or the reaction is not expected.
Next, slowly add suitable reagents, and at the same time apply exquisite temperature control means. The temperature is just like the reins of the reaction. If it is too high, the reaction will be excessive, and if it is too low, it will be difficult to proceed slowly. Make sure that the temperature is constant in a certain range, so that the reaction can advance steadily. < Br >
During the process, it is necessary to stir with moderate force to make the material blend seamlessly and the reaction is uniform. And pay close attention to the signs of the reaction, such as the change of color, the birth and death of bubbles, etc., which are all characteristics of the reaction process.
When the reaction is coming to an end, carefully separate the product. Or use filtration to separate solid and liquid; or use distillation to extract a pure product according to the difference in boiling point.
Finally, the product is tested in detail to verify its purity and composition, and it is indeed in line with the required standards. In this way, trichlorotetrahydroxy dioxpentaisonitrile tricarboxylic acid can be prepared. During the steps, interlocking, a little careless, it will be in vain, so the operator must be fully focused, with exquisite skills, into this system.

Arsenic trioxide, sulfur dioxide, phosphorus pentoxide, carbon monoxide, sulfur trioxide and other substances do have many things to pay attention to when storing and transporting.
First of all, the storage place should be selected in a cool and ventilated place. Therefore, these substances are chemically active, and high temperature may cause them to react, causing danger. For example, arsenic trioxide, although solid, if heated, or cause its volatilization to intensify, its toxicity is very strong. If it is inhaled by humans after volatilization, it will be very harmful to the body.
Second, such substances need to be sealed and stored. Sulfur dioxide, carbon monoxide and other gases are easily dissipated. If they are not sealed, they will not only pollute the environment, but may also cause accidents such as poisoning. And sulfur trioxide has strong water absorption. If it is not sealed, it is easy to react with water vapor in the air, generate sulfuric acid, and corrode the storage container.
Furthermore, the storage area should be kept away from fire and heat sources. Like carbon monoxide, it is flammable, and it will cause combustion and explosion in case of open flame and high heat energy, which will endanger the safety of the surrounding area.
When transporting, you should not slack off. First, you need to choose the right means of transportation. For toxic and harmful gases, such as sulfur dioxide and carbon monoxide, special gas transportation equipment should be used to ensure good sealing. Second, transporters should be familiar with relevant safety knowledge and emergency treatment methods. If there is an accident such as leakage during transportation, it can be dealt with in a timely and appropriate manner to reduce harm. If phosphorus pentoxide leaks, it should not be flushed directly with water, as it will react violently in contact with water. It should be covered with dry sand and then properly disposed of.
In addition, whether it is storage or transportation, it should strictly follow relevant regulations and standards, and make signs so that others can clearly know the nature and hazards of the stored and transported items, so as to ensure safety.

Today there are 3% 2C4 (this expression is not clear, it will be omitted for the time being), and there are also dioxy, 5, isoamyl ether, 3, and carboxylic acids. The impact on the environment and human health will be analyzed in detail.
Dioxy, there are many kinds, if it is dioxin, its toxicity is very strong. This substance is chemically stable, difficult to degrade, and easy to accumulate in organisms. In the environment, it can remain for a long time, polluting soil, water sources and air. If people are exposed to it, or ingested through respiration and diet, it can cause a variety of health problems, such as disrupting the endocrine system, affecting reproductive function, and even inducing cancer, which can also damage the immune system and nervous system.
5, it is not clear what it refers to, so it is difficult to detail its effects.
Isoamyl ether, volatile. In the environment, it evaporates into the air, or causes air quality to decline. If inhaled, or irritates the respiratory tract, causing symptoms such as cough and asthma. Long-term exposure may damage the nervous system and liver and kidney functions. If it flows into water bodies, it may affect the survival of aquatic organisms and destroy the ecological balance of water.
3, there is no detail, and the impact is difficult to determine.
Carboxylic acids, there are various types. Some carboxylic acids are corrosive, and if accidentally contacted with the skin and eyes, they can cause burns. In the environment, some carboxylic acids participate in the natural metabolic cycle, while some synthetic carboxylic acids are difficult to degrade, and will affect the ecology after accumulation. If it is highly acidic, or changes the pH of soil and water, it will affect plant growth and aquatic habitat. For humans, excessive oral intake of some carboxylic acids may irritate the gastrointestinal tract and cause discomfort.
In summary, in addition to the unspecified 3 and 5, dioxygen (if dioxin), isoamyl ether, and carboxylic acid all have different degrees of impact on the environment and human health. It should be treated with caution and reasonably controlled to ensure the environment and human health.
