The main use of 2-% chloroethyl arsine is involved in "Tiangong Kaizi", which is related to the use of medicine, agriculture and industry.
In the process of medicine, it has been used to prepare specific agents in the past. Cover 2-% chloroethyl arsine has unique chemical properties and can interact with certain substances in the body. Although its toxicity is quite large, after proper treatment and deployment, it may have been tried to treat certain diseases in the past medical exploration, but now it is less and less used for medical purposes due to its toxicity risk.
As for agriculture, it can be used as a raw material for special pesticides. Due to its chemical activity, it can show inhibition or killing effect against specific pests and bacteria. For example, in the past, some areas have tried to use preparations containing 2% chloroethyl arsine to control stubborn pests and diseases in farmland, hoping that it can protect crops and increase their yield. However, due to the potential harm to the environment and biology, such pesticides containing highly toxic ingredients are gradually abandoned today.
In the industrial field, 2% chloroethyl arsine can be used as an intermediate in organic synthesis. In the chemical synthesis process, with its special chemical structure, it can participate in the synthesis of a variety of complex organic compounds. For example, the preparation of specific polymer materials, fine chemicals, etc., through the reaction of introducing specific functional groups to achieve the required properties and structures of the product. However, in view of its toxicity and environmental impact, the industry is constantly seeking safer and more environmentally friendly alternatives for related synthesis.

2-% cyanoacetamide is an organic compound. Its physical properties are as follows:
Appearance, white to pale yellow crystalline powder at room temperature, fine texture, this form is easy to store and use.
Melting point is about 119-121 ° C. When the temperature rises to this range, 2-% cyanoacetamide melts from solid to liquid. This property is of great significance for the separation, purification and control of reaction conditions in chemical production.
Solubility, it is soluble in polar solvents such as water, ethanol, and ether. When dissolved in water, by virtue of the hydrogen bonds formed between molecules and water molecules, they are uniformly dispersed in water to form a stable solution; in organic solvents such as ethanol and ether, they are also dissolved by the principle of similar phase dissolution. This property facilitates its application in different chemical reaction systems, and can be uniformly dispersed in suitable solvents as reactants or intermediates to promote the smooth progress of the reaction.
In addition, 2 -% cyanoacetamide has relatively stable chemical properties at room temperature and pressure, but under specific conditions, such as high temperature, strong acid, strong base, or the presence of specific catalysts, chemical reactions will occur, exhibiting active chemical properties, participating in various organic synthesis reactions, and generating new organic compounds.

2-% propane (2-Hydroxypropane) has a specific chemical property. Its properties can be divided into physics and chemistry.
First of all, its physical nature. Under normal conditions, 2-% propane is mostly a transparent liquid, with a special smell. Its boiling phase is not high, and it has a certain degree of stability. This property makes it easy to vaporize and dissipate in some environments. In addition, its density is slightly lower than that of water, and it has a certain solubility in water. This solubility is affected by factors such as solubility and resistance.
As for the solubility, 2-% propane has the typical reaction of alcohol because it contains hydroxyl groups (-OH). First, it can be activated. Gold such as gold and other organic reactions. Such as 2-% propane, the atom of the propane in the propane group is reversed, and the inverse equation is obtained. The inverse equation is roughly: 2 -% propane + 2Na → 2 -% propane + H2O ↑. Second, it can be esterified and reversed. Carboxylic acid co-, under catalytic and appropriate conditions, the carboxyl group is combined with water to form ester compound water. For example, acetic acid can be reversed, 2 -% propane acetate can be obtained, and the inverse formula is: 2 -% propane + CH 🥰 COOH CH 🥰 COOCH (CH 🥰) ³ + H2O O. In addition, 2 -% propane can also generate oxidation reactions under the action of oxidation. According to the strength of oxidation and the reaction of different parts, different compounds can be formed. If the appropriate oxidation and reaction parts are used, they can be oxidized into ketone compounds.
Therefore, 2 -% propane has the above-mentioned chemical properties due to its special molecular properties. It has its important uses and intentions in chemical, chemical and other fields.

The method of making 2-% cyanoethylfuran has several ends. If you want to make this product, you should first check the raw materials and various conditions used.
One method can start from furan and make it an addition reaction with acrylonitrile in the presence of a suitable catalyst. This reaction needs to be controlled at an appropriate temperature and pressure, and a suitable catalyst is selected to make the reaction smooth. For example, a metal complex with high activity is selected as the catalyst. At a certain temperature range, furan and acrylonitrile can be gradually added to form 2-% cyanoethylfuran. During this period, if the temperature is too high or side reactions occur, if it is too low, the reaction rate will be slow, so accurate temperature control is essential.
There is another method, which can be obtained by the multi-step reaction of organic synthesis. First take a compound with a specific functional group, and after several transformations, it will gradually introduce cyanoethyl and furan structures. Although this process is a little complicated, if the steps are well designed, the target product can be efficiently prepared. For example, a halogenated hydrocarbon is first reacted with sodium cyanide to obtain a cyanyl substitute, and then through condensation and cyclization of furan-related derivatives, 2-% cyanoethylfuran is finally obtained. Each step of the reaction needs to pay attention to the control of the reaction conditions, such as pH, reaction time, etc., to avoid the generation of impurities.
In addition, there are also methods of biosynthesis. Find microorganisms or enzyme systems with specific enzyme activities, and use the metabolic pathway in the organism to catalyze the synthesis of 2-% cyanoethylfuran. This route has the advantages of green and environmental protection, but it has high requirements for the cultivation and regulation of biological systems. It is necessary to precisely create an environment suitable for microbial growth and enzyme activity, such as suitable nutrients, pH and temperature, in order to smooth biosynthesis and obtain pure 2-% cyanoethylfuran.

2-% propane fire In the course of use, pay attention to the following things.
First, take the right place. This fire device is suitable for use in well-connected, flammable and crowded areas. If it is applied in a dense air, or due to insufficient oxygen, it will produce toxic emissions such as carbon monoxide, endangering personal safety; and in the event of a fire, it will be used in a dense air to escape. And if it is close to flammable materials, such as dry grass, oil, etc., it is easy to cause a fire if you are not careful, and it will form a huge fire.
Second, check the equipment carefully. Check the tank before use, and it will leak or break. If there is a crack or leak in the tank body, it can ignite and escape, and it will explode immediately in case of open fire or high temperature. At the same time, it is also necessary to check whether the nozzle is open. If there is a blockage, it may cause normal burning, or even tempering, causing dangerous burning.
Third, it is used for positive operation. Source,, do not leave the whole thing, in case the fire is urgent, so as to control the burning. In the case of fire, it is appropriate to use a lighter or match, and keep a certain distance to avoid sudden explosion and burn yourself. During the use period, do not make any sense of the size of the whole flow, in order to prevent the flame from bursting.
Fourth, store it properly. After use, and source, when the fire is cold, store it in, dry and children and. If it is placed in a humid environment, the appliance is prone to corrosion, which affects its performance and safety; if it is easy for children, it will be too late to regret the accident due to operation.
Therefore, 2-propane fire is not used, but it is necessary to pay attention to all things used to ensure safety.
