3-Methoxyphenyl is one of the organic compounds, which has the following chemical properties:
- ** Nucleophilic Substitution Reaction **: The electron cloud density on the benzene ring increases due to the methoxy donator effect, making the benzene ring ortho and para-sites more susceptible to attack by nucleophilic reagents. If under appropriate conditions, nucleophilic substitution can occur with halogenated hydrocarbons, and methoxy ortho or para-hydrogen is replaced by hydrocarbon groups in halogenated hydrocarbons to form new organic compounds. This reaction is of great significance for the construction of complex organic molecular structures, and can introduce different functional groups to expand the application scope of compounds.
- ** Oxidation Reaction **: Methoxy groups can be oxidized by specific oxidants. In the case of strong oxidants, the valence state of the oxygen atom in the methoxy group may change, resulting in products containing different oxidation states. The common reaction is that the methoxy group is oxidized to a hydroxyl group or a higher valence state oxygen-containing functional group. This oxidation reaction can be used to prepare phenols or other oxygen-containing derivatives with specific structures.
- ** Reduction Reaction **: The benzene ring can be reduced under specific conditions. For example, under catalytic hydrogenation conditions, some or all of the double bonds on the benzene ring can be reduced to single bonds to generate corresponding cyclohexane derivatives. This reduction reaction can change the spatial structure and chemical activity of the molecule, providing raw materials for the subsequent synthesis of different types of compounds. < Br > - ** Acylation Reaction **: Under the catalysis of Lewis acid, 3-methoxyphenyl can be acylated with acyl halide or acid anhydride, and acyl groups are introduced into the phenyl ring to form compounds with carbonyl functional groups. This reaction is widely used in organic synthesis fields such as fragrances and drugs, giving the products unique chemical properties and biological activities.

3-Aminoethoxy vinyl glycine, its main purpose is to regulate plant growth and development, which can effectively delay plant aging, thereby prolonging the fresh-keeping time of cut flowers and improving crop storage quality.
Watching the world's plants and trees, flowers bloom sometimes, and flowers fade sometimes. However, cut flowers leave branches, what is their lifespan? If you want to prolong their youth, 3-aminoethoxy vinyl glycine can do this. This is because it can inhibit the synthesis of ethylene in plants. Ethylene, plant hormones, also have the ability to promote plant aging and fruit ripening. 3-Aminoethoxy vinyl glycine is like a delicate gate, blocking the way of ethylene generation, slowing down the aging of cut flowers.
As for crops, they are also benefited by it. Such as melons and fruits, they are perishable after maturity and difficult to last for a long time. 3-Aminoethoxy vinyl glycine can extend its storage period, maintain its quality between storage and circulation, and reduce the risk of loss.
Furthermore, in the whole process of plant growth and development, 3-Aminoethoxy vinyl glycine also has the function of regulation. It can make plant physiological processes more coordinated and the growth situation more stable. It can play a role in regulating during flowering or shaping plant morphology. It can help plants glow more vitality and add a different color to nature and the world. It is an indispensable good agent in the field of agriculture, planting and horticulture.

The preparation methods of 3-aminoethoxyethylene include the following:
First, halogenated ethanol and ammonia are used as raw materials. Take an appropriate amount of halogenated ethanol, place it in a clean reactor, and slowly introduce ammonia gas. This reaction needs to be carried out at a suitable temperature and pressure, usually maintained at about [X] ° C, and the pressure is about [X] MPa. The ammonia gas undergoes a substitution reaction with halogenated ethanol, and the halogen atom is replaced by an amino group, thereby generating 3-aminoethoxyethylene. After the reaction, the product is separated and purified by distillation, extraction and other means to obtain pure 3-aminoethoxyethylene.
Second, the method of reacting ethylene oxide with amine compounds is used. Mix ethylene oxide with a specific amine compound in a certain proportion and put it into a reaction vessel. During the reaction process, an appropriate amount of catalyst needs to be added to accelerate the reaction process. The reaction conditions are also very critical. The temperature should be controlled at around [X] ° C, and the reaction time is about [X] hours. After ring opening, ethylene oxide is combined with amine compounds to form 3-aminoethoxy ethylene. After the reaction is completed, it goes through a series of post-processing operations, such as filtration, distillation, etc., to obtain the desired product.
Third, it is prepared by the aminolysis reaction of alcohols. Select a suitable alcohol, such as an alcohol containing a specific functional group, and carry out an aminolysis reaction with ammonia gas in the presence of a specific catalyst. This reaction requires precise regulation of parameters such as temperature, pressure and reaction time. At the appropriate temperature [X] ℃, pressure [X] MPa and reaction time [X], the hydroxyl groups in the alcohol molecules are replaced by amino groups to gradually generate 3-aminoethoxyethylene. The subsequent separation and purification steps are also required to achieve the purity of the product.

3 - Aminoethoxyethylene needs to pay attention to many matters during storage and transportation.
For storage, first, a dry, cool and well-ventilated place should be selected. This is because the substance may be sensitive to temperature and humidity, humid, high temperature or poorly ventilated environment, which is prone to change its properties, or even cause dangerous reactions. Second, it should be stored in isolation from oxidants, acids, etc. 3 - Aminoethoxyethylene is chemically active, in contact with oxidants, or cause severe oxidation reactions, and in case of acids, or chemical reactions may occur, resulting in deterioration or danger. Third, the storage container must be tightly sealed. Sealing can prevent its volatilization and escape, avoid reaction with air components, and prevent leakage, endangering the surrounding environment and personal safety.
As for transportation, the first thing to do is to ensure that the packaging is complete and firm. Vibration and collision during transportation are inevitable. If the packaging is not strong, it is easy to cause leakage. Secondly, the transportation tool needs to be clean, dry and free of other chemicals. Residual chemicals or react with 3-aminoethoxyethylene, resulting in a significant increase in transportation risk. In addition, the transportation personnel should be professionally trained and familiar with the characteristics of the substance and emergency treatment methods. In case of leakage during transportation, the transportation personnel can respond in a timely and correct manner to reduce the harm. In addition, the transportation process should strictly follow relevant regulations and standards, travel according to the specified route and time, and must not be changed at will to ensure transportation safety.
