2-tert-butyl-1,1,3,3-tetramethylguanidine, this substance is an organic compound. Its physical properties are unique, let me tell them one by one.
Looking at its properties, it is mostly colorless to light yellow liquid under normal conditions, with a clear appearance and good visibility. Smell it, or have a special smell, but it is not pungent and intolerable, it has a certain volatility, and can gradually spread in the air.
When it comes to the melting point, it is about -40 ° C, and it is solid at low temperature. The boiling point is quite high, and under normal pressure conditions, it can reach 240 ° C. This characteristic makes it still able to maintain a liquid state in a higher temperature environment, and it is not easy to vaporize and dissipate.
Its density is nearly 0.88g/cm ³, which is slightly lighter than water. If it is co-placed with water, it can float on the water surface. It is slightly soluble in water, but has good solubility in organic solvents, such as ethanol, ether and other organic solvents. Due to the molecular structure characteristics, its structure has good compatibility with organic solvents.
In addition, the vapor pressure of 2-tert-butyl-1,1,3,3-tetramethylguanidine is low, indicating that its volatilization rate is relatively slow at room temperature, and it can reduce the loss and risk caused by volatilization during storage and use.
In summary, the physical properties of 2-tert-butyl-1,1,3,3-tetramethylguanidine, such as appearance, odor, melting and boiling point, density, solubility, and vapor pressure, etc., make it unique in many fields such as organic synthesis. It provides strong support for chemical production and scientific research experiments.

The synthesis method of 2-tert-butyl-1,1,3,3-tetramethylguanidine is not detailed in the classic "Tiangong Kaiwu", but in the traditional process, similar ideas can be found for reference.
Ancient chemical industry depends on the accumulation of experience and simplicity. To synthesize this substance, you can start from the selection of raw materials. Compounds containing tert-butyl, methyl and other corresponding groups should be found as starting materials.
One, or you can try to react with guanidine-containing precursors with halogenated hydrocarbons containing tert-butyl. In the kettle, a suitable solvent, such as alcohol or ether, is adjusted to the appropriate temperature, or it needs to be heated, so that the halogen atom of the halogenated hydrocarbon reacts with the guanidine precursor. In this process, when attention is paid to the control of the reaction conditions, if the temperature is too high, side reactions will occur, and if it is too low, the reaction will be slow.
Second, it is also conceivable to use methyl-containing aldose and ketone compounds to construct the guanidine skeleton through a series of steps such as condensation and amination, and then tert-butyl is introduced. When condensation, or an acid or base is used as a catalyst to promote the condensation of aldose, ketone and nitrogen-containing compounds. When ammoniating, choose a suitable ammonia source, such as ammonia gas or ammonium salt, and under specific conditions, connect the nitrogen atom to form a guanidine group. When tert-butyl is introduced later, mild and selective reagents and conditions should be selected to prevent damage to the formed skeleton.
In addition, the ancient method also emphasizes the use of mediators. Or natural things, such as certain plant extracts or minerals, can be found as the reaction medium to help it occur smoothly. And in the operation, when the ancient craftsman, carefully observe the reaction phenomenon, adjust the reaction process in time according to the change of color, smell and state. Although "Tiangong Kaiwu" does not have this precise synthesis guide, it is possible to find a way to synthesize this compound by following the chemical wisdom of ancient times and following the properties and reaction laws of materials.

2-tert-butyl-1,1,3,3-tetramethylguanidine is a strong base commonly used in organic synthesis. When using, many things need to be paid attention to.
First, safety protection must be comprehensive. This substance is corrosive and irritating to the skin, eyes and respiratory tract. When operating, be sure to wear appropriate protective equipment, such as protective glasses, gloves and lab clothes, to avoid contact with skin and eyes. If you come into contact accidentally, rinse with plenty of water immediately and seek medical attention in a timely manner.
Second, storage conditions should not be ignored. Store in a cool, dry and well-ventilated place, away from fire and heat sources, and avoid mixing with oxidants, acids and other substances to prevent dangerous reactions.
Third, the reaction conditions are strictly controlled. Because of its strong alkalinity, when participating in the reaction, the reaction conditions such as temperature, time and the ratio of reactants have a significant impact on the reaction process and product formation. It should be precisely regulated according to the specific reaction needs to achieve the desired effect.
Fourth, the post-treatment process should be careful. After the reaction, when the product is separated and purified, an appropriate method should be selected according to its characteristics. Because of its alkalinity, neutralization and other means may be taken during the treatment to properly obtain pure products and ensure environmental safety.
