3 - [2 - (2 - aminoethylamino) ethylamino] propyltrimethoxysilane, this is an organosilicon compound. During use, many things should be paid attention to. First priority safety protection. This compound may be irritating and can cause discomfort in contact with the skin, eyes or inhalation of its volatiles. Therefore, when operating, be sure to wear suitable protective equipment, such as gloves, protective glasses and masks. In case of inadvertent contact, rinse with plenty of water immediately. In severe cases, seek medical attention immediately. This is the storage condition. Store in a cool, dry and well-ventilated place, away from fire and oxidants. Because of its methoxy group, it is exposed to high temperature, open flame or oxidant, or there is a risk of combustion or explosion. The storage container must also be sealed to prevent moisture hydrolysis and affect its performance. The other is the method of use. Before application, it is necessary to fully understand its chemical properties and reaction characteristics. Because its active groups can participate in a variety of chemical reactions, the reaction conditions should be precisely controlled during use, such as temperature, pH value and reaction time, in order to achieve the expected reaction effect and avoid side reactions. Repeated is compatibility. When using, consider its compatibility with other substances and avoid mixing with chemicals that can cause adverse reactions. If mixed with other solvents and additives, a small test should be carried out in advance to ensure its stability and performance are not affected. The last is environmental impact. During use, care should be taken to avoid leakage into the environment. If there is a leakage, proper cleaning measures should be taken in time to prevent pollution to soil, water sources, etc. Because it degrades in the environment or has a certain impact on the ecosystem, it is necessary to adhere to the concept of environmental protection, rational use and disposal.

To prepare 3 - [2 - (2 - aminoethylamino) ethylamino] propyl-trimethoxysilane, the method is as follows: First take trimethoxysilane and place it in a clean reactor. The kettle should be made of glass so that the reaction condition can be observed. Then the amine compound containing alkenyl groups, such as allylamine, is slowly dripped into the kettle. When dripping, the temperature should be controlled, and the temperature should be maintained in a water or oil bath to maintain the appropriate range, about 40 to 60 degrees Celsius. This is because the temperature is too high, the reaction is too fast, and it is easy to produce side effects; if it is too low, the reaction will be slow and take a long time. The process of dripping is carried out at a uniform speed, accompanied by moderate stirring, so that the two are fully mixed. A magnetic stirrer can be used for stirring, and the rotation speed is moderate to promote a uniform reaction. After dripping, it is still necessary to maintain the temperature, so that the reaction lasts, about 3 to 5 hours. During this period, samples can be taken regularly, and the progress of the reaction can be measured by thin layer chromatography or gas chromatography. When the reaction is nearly complete, cool down to room temperature. Then, the raw materials and by-products that have not been reacted are removed by distillation under reduced pressure. During distillation, the pressure should be controlled at an appropriate value to effectively separate the product from the impurities. In this way, a purer 3- [2- (2-aminoethylamino) ethylamino] propyl-trimethoxysilane can be obtained. When operating, be sure to pay attention to safety, such as wearing protective equipment and opening ventilation equipment to avoid danger.

3 - [2 - (2 - aminoethylamino) ethylamino] propyltrimethoxysilane, this product has several advantages over other similar products. One of its advantages is that the reactivity is very different. The amino functional group of this silane is very active and can react quickly and efficiently with many compounds. For example, when it encounters materials containing carboxyl groups and epoxy groups, it can quickly form a stable chemical bond, which is like a tenon-mortise fit and is closely connected. Therefore, in the crosslinking and coupling reactions, it can often show its skills, efficiently promote the reaction process, and greatly improve the performance of the product. Furthermore, its compatibility is excellent. It is well compatible in a variety of organic polymer systems, just like fish swimming in water and fusing freely. Whether it is a common resin system or a special polymer material, this silane can coexist harmoniously with it, which helps to uniformly disperse, improve the uniformity and stability of the material as a whole, and then optimize the comprehensive performance of the product. And its hydrolysis stability is also excellent. Even in a relatively humid environment, its trimethoxysilane group hydrolysis rate is moderate, neither too fast hydrolysis will cause premature failure, nor too slow and affect the application effect. This characteristic makes the silane more convenient and stable during storage and use, greatly expanding its application scenarios and applicable conditions.
