1-Alkane, a genus of organic compounds, contains mostly carbon and hydrogen elements, and its properties are relatively stable. It is mostly gas, liquid or solid at room temperature. When burned, carbon dioxide and water can be produced, and it is often a source of fuel, such as methane and ethane, which are widely used in industry and people's livelihood. Its chemical properties are peaceful, and it is not easy to change violently with other things. However, under specific conditions, it can also perform various reactions such as substitution.
2-aminoethanol, with the properties of alcohol and amine. First, it has the properties of alcohol hydroxyl group, which can react with acid esterification, raw ester and water. Under the action of oxidation agent, it can be converted into aldehyde or acid. Second, because it contains amino groups and is alkaline, it can form salts with acids, and can also react with acylated halides, acid anhydrides, etc. And aminoethanol can be used as a solvent and is widely used in chemical industry, medicine and other fields. Because it has both alcohol and amine groups in its molecules, its chemical properties are active and changeable, and it can participate in many complex chemical reactions. It is an important raw material for organic synthesis. It is also commonly used in the preparation of surfactants, pharmaceutical intermediates and other substances. It has a significant position and extraordinary function in industrial production and scientific research.

1 - Nai bean, rice and other things are ground and mixed with water to form a mixture, leaven, steaming and other processes, and the purpose is different. In the way of food, it can be used as a kind of pasta, such as rice, its softness, is one of the daily staple foods of the people; and such as steamed buns, which can be wrapped with various ingredients, all sweet, all kinds of shapes and colors, and rich in taste. In addition, it can also be used as a cake, such as rice cake, with a dense taste, sweet and fragrant nose, and a good traditional and common delicacy.
2 - Aminoethanol was named in ancient times, but it was recommended for its use due to its nature, or it can be used in some special industries. It can be used for things, or it can be used as a material for materials, to help shape, fix, etc. Because aminoethanol has a certain solubility and activity, it can disperse the components of the aid, which is beneficial to the effect. In the leather process, it can be used for the leather treatment process. Leather needs to be tanned in multiple processes, aminoethanol or can be tanned liquid, so that the leather is soft and durable, and the color is better. In the process, it can be used as an aid to improve the properties of the product, such as increasing the flexibility and resistance of the product, etc., so that the product is better. In short, its use is in the micro-process of various processes, and the development of general technologies is promoted.

To prepare 1-hydrocarbon-2-aminoethanol, there are various methods.
First, it can be obtained by reacting ethylene oxide with ammonia. Ethylene oxide, a genus of cyclic ethers, has active properties. Ammonia is nucleophilic and can attack the carbon of ethylene oxide, causing cyclization and producing 2-aminoethanol. This reaction condition is easier to control, and ammonia can be used as a raw material with a wide range of sources.
Second, it can also be obtained by reacting halogenated ethanol with ammonia. Halogenated ethanol has high halogen atom activity, and the nitrogen atom of ammonia is nucleophilic and can replace the halogen atom to form 2-aminoethanol. The preparation of only halogenated ethanol may require multiple steps, and the selection of raw materials and the control of reaction conditions need to be
Third, the aldehyde, ammonia and hydrogen can be prepared by reductive amination reaction. The aldehyde and ammonia form an intermediate of imine, and then reduced by hydrogen to obtain 2-aminoethanol. This way requires a suitable catalyst, such as a metal catalyst, to increase the reaction efficiency and selectivity.
Or it can be obtained from alcohol and converted in multiple steps. First, the alcohol is oxidized to aldehyde or carboxylic acid, and then an amino group is introduced through a series of reactions, and then reduced to 1-hydrocarbon-2-aminoethanol. However, this path is lengthy and the steps are cumbersome, and each step of the reaction needs to be carefully planned to avoid side reactions and increase the yield.
All this number method has advantages and disadvantages. The raw materials of the ethylene oxide method are easy to obtain and the reaction is direct; the halogenated ethanol method relies on the preparation of halogenated ethanol; the reduction amination requires a high-efficiency catalyst; the steps of the alcohol conversion method are complicated. In actual preparation, the choice is based on factors such as raw material availability, cost, reaction conditions and product purity.

When storing and transporting 1-alkane-2-aminoethanol, the following things should be considered:
The temperature and humidity of the first environment. These two have a significant impact on the quality of 1-alkane-2-aminoethanol. If the temperature is too high, it may cause its volatilization to accelerate, and increase the risk of explosion; if the humidity is too high, it may cause its hydrolysis and other chemical changes, which will damage its purity. Therefore, when storing, when setting up temperature control and dehumidification devices, keep the temperature in a suitable area, usually 15 ° C - 35 ° C is the best, and the humidity control is 40% - 60%.
The second consideration is the solid density of its packaging. 1-Alkane-2-aminoethanol is corrosive and volatile to a certain extent. If there is an omission in the packaging, one will damage the surrounding objects, and the other will be that the escaping gas can pollute the environment and endanger humans and animals. When filled with corrosion-resistant materials, such as glass, specific plastics or metal containers with protective layers inside, and tightly sealed to prevent its leakage.
Furthermore, avoid co-storage and co-transportation with contraindicated substances. 1-Alkane-2-aminoethanol can cause severe reactions when exposed to acids, strong oxidants, etc., and is at risk of heat generation and explosion. Therefore, when warehousing and transportation, it must be kept away from acids, strong oxidants, etc., stored in separate warehouses, and transported in separate vehicles. It must not be mixed and transported.
It is also necessary to clearly identify the warning signs. In the place of storage and transportation, clear warning signs should be affixed, such as "corrosive" and "flammable", so that everyone knows the risk and handles it with caution.
And during transportation, the traffic should be stable to avoid bumps and vibrations. Violent shaking or damage to the package, causing the disaster of leakage. Drivers and escorts should also be familiar with emergency measures. In case of emergencies, they can take measures quickly to reduce the damage to a minimum.

Rivers and rivers are the blood of the earth, nourishing all things, and related to the survival of life and soul. And carbamate has a great impact on the environment and human health.
In the realm of viewing the environment, if carbamate flows into rivers, it will bear the brunt of the organisms in the water. It may be toxic, causing fish, turtles, shrimp and crabs and other aquatic species to contract diseases or die, causing the aquatic ecological chain to collapse and break. And its residue in the soil will also affect the micro-ecology of the soil, hindering the growth of beneficial microorganisms, destroying the fertility and structure of the soil, and then harming the crops and making the grains unavailable.
As for human health, the harm of carbamate should not be underestimated. If people come into contact with this substance through diet, breathing, etc., it may damage the nervous system. In light cases, they may feel dizzy, nausea and vomiting; in severe cases, they may cause neurological disorders and endanger life. And it may be potentially carcinogenic. Long-term exposure to the environment containing carbamate will greatly increase the risk of cancer. And because it can be absorbed through the skin, if it is improperly protected during production and use, it will also damage the skin, causing itchy rashes, redness and swelling.
Therefore, the use and discharge of carbamate should be treated with caution. Complete regulation and strict monitoring are required to ensure the personal well-being of Jianghe Changqing and prevent the invasion of this harmful substance.
