###Preliminary preparation
To prepare this product, all kinds of raw materials and utensils need to be prepared first. Raw materials such as corresponding amines, halogenated hydrocarbons, methyl-containing alkenes, etc., all need to be of correct quality and purity. The utensils include reactors, condensers, thermometers, stirrers, etc., which are readily available and clean for correct use.
####Synthesis steps
1. ** Preliminary reaction of amine groups **: In the reaction kettle, add an appropriate amount of 1, 2, 3, 4-tetraamine, use alcohol as solvent, such as ethanol or isopropanol, and add a basic catalyst, such as potassium carbonate or sodium hydroxide, in a certain ratio. When heated to 60-80 ° C, slowly add an appropriate amount of halogenated hydrocarbons dropwise. The structure of this halogenated hydrocarbon needs to meet the needs of the reaction. Add it dropwise and stir at constant temperature for a few times to fully react with the halogenated hydrocarbon to form a preliminary intermediate product. During this process, pay close attention to the temperature and reaction phenomena to prevent accidents.
2. ** Methylation reaction **: When the previous reaction is over, cool down to room temperature, and move the preliminary intermediate product to a new reaction kettle. Add an appropriate amount of 2,2,4,7-tetramethyl-halide (according to the structure of the target product), use dichloromethane or tetrahydrofuran as solvent, and add an appropriate amount of Lewis acid catalyst, such as aluminum trichloride or zinc chloride. When the temperature is raised to 40-60 ° C, the methylation process is realized. In this step, the reaction conditions are finely adjusted to ensure that the methyl group is precisely connected to the predetermined position.
3. ** Ether formation reaction **: After the methylation product is separated and purified, it is then added to the reactor. Add the corresponding alkenyl alcohol and dehydrating agent, such as concentrated sulfuric acid or p-toluenesulfonic acid, and dehydrate to ether at 100-120 ° C. During the reaction, the volatile solvent and reactant are recovered by refluxing in a condenser tube. After a few hours, the target product can be obtained. 1% 2C2% 2C3% 2C4-tetraamine-2% 2C2% 2C4% 2C7-tetramethyl-divinyl ether crude product.
4. ** Purification and Refinement **: The crude product is distilled under reduced pressure, and the corresponding fraction is collected according to the boiling point of the target product to remove high-boiling point and low-boiling point impurities. Then it is further purified by column chromatography. Appropriate silica gel and eluent are selected, and the pure target product is collected and bottled for proper storage.
The whole process of synthesis, strictly abide by the operating procedures, pay attention to safety protection, and precisely control the reaction conditions to obtain the best product.

1% 2C2% 2C3% 2C4 -tetrahydro- 2% 2C2% 2C4% 2C7 -tetramethylpentyl ether During use, pay attention to the following numbers.
First, this material has a specific chemical activity. In the storage environment, be sure to keep it in a cool, dry and well-ventilated place, away from fire and heat sources, to prevent accidental explosion. Because of its flammability, if it is not properly stored, it is easy to cause fire or even explosion in case of open flame or hot topic.
Second, when using, strictly follow the operating procedures. The operator should wear suitable protective equipment, such as protective gloves, goggles, gas masks, etc. This is because the substance may be sensitizing and irritating to the skin, eyes, and respiratory tract. If you accidentally touch the skin, you should quickly rinse with a lot of water. If you feel unwell, you should seek medical consultation; if you splash into the eyes, you should also immediately rinse with flowing water and seek medical attention as soon as possible.
Third, the use environment should be well ventilated. Because of its volatilization of steam or air pollution, it is harmful to human health. Ensure that the working space is well ventilated, which can effectively reduce its concentration in the air and reduce the risk of inhalation.
Fourth, disposal must be carried out in accordance with regulations. Do not dump it at will to prevent pollution to the environment. It should be properly handled by a professional organization in accordance with local environmental regulations.
In short, in the entire use of 1% 2C2% 2C3% 2C4 - tetrahydro- 2% 2C2% 2C4% 2C7 - tetramethylpentyl ether, safety and environmental protection are essential. Only with caution can we avoid disasters and ensure people's safety.
