What are the physical properties of 1,1-bis (2-methylphenyl) guanidine?
1% 2C1-bis (2-methylbenzyl) ether, which has the following physical properties:
Its shape, at room temperature, 1% 2C1-bis (2-methylbenzyl) ether is colorless to light yellow transparent liquid, its texture is uniform, without visible impurities or suspended solids, and it is clear.
Smell its gas, this material emits a special aromatic smell, but its taste is not rich and pungent, but has a certain degree of softness. In a well-ventilated place, the smell is still pleasant, but if it is in a closed space, the smell may be slightly stronger.
Measure its melting and boiling point, the melting point is low, it is liquid at room temperature, and the boiling point is relatively high, about a certain temperature range. This characteristic makes it stable in liquid state under general heating conditions, and it is not easy to quickly vaporize and evaporate, which provides convenience for its application in some specific reactions or processes.
Measure its density, compared with common organic solvents, the density is moderate, neither too light to float on water, nor too heavy to quickly sink to the bottom. When mixed with other liquids, it presents different mixed states due to density differences, which can be used for separation or mixing operations.
Looking at its solubility, 1% 2C1-bis (2-methylbenzyl) ether is soluble in a variety of organic solvents, such as ethanol, ether and other common organic solvents, and can be well miscible with it. However, the solubility in water is very small. This difference in solubility is quite valuable in chemical separation, extraction and other operations.
Observe its volatility, although the boiling point is high, it still has a certain volatility. In an open environment, some volatilization will be lost over time. Pay attention when storing and using it. It should be properly sealed to prevent its loss or concentration change due to volatilization.
What is the preparation method of 1,1-bis (2-methylphenyl) guanidine?
To prepare 1,1-bis (2-methylphenyl) alkyne, you can follow the following ancient method.
First take an appropriate amount of 2-methylphenyl halide and place it in a clean reactor. Add a suitable base, such as potassium carbonate, to adjust the acid-base environment of the reaction. The amount of base needs to be precisely controlled, and excess or insufficient can affect the process of the reaction and the purity of the product.
Then introduce an appropriate amount of acetylene derivatives, and the ratio needs to be strictly formulated to ensure that the reaction can proceed in the expected direction. During this process, the reaction temperature needs to be closely monitored and maintained within a specific range, generally within a certain temperature range, such as between [X] ° C and [X] ° C. If the temperature is too high, it is easy to initiate side reactions, resulting in complex and impure products; if the temperature is too low, the reaction rate will be slow and time-consuming.
At the same time, an appropriate amount of catalyst can be added to accelerate the reaction. This catalyst should have the characteristics of high efficiency and stability without causing too many side reactions. During the reaction, stirring should be continued to make the reactants fully mixed and contacted to promote the uniform occurrence of the reaction.
When the reaction is carried out to a certain extent, the reaction process should be monitored by suitable analytical means, such as thin-layer chromatography, etc. When the raw materials are exhausted and the amount of product generated is stable, the reaction can be regarded as completed.
Then, the reaction mixture is separated and purified. First, the product is extracted from the reaction system by organic solvent extraction. Then, through distillation, recrystallization and other operations, the product is further purified and impurities are removed to obtain high-purity 1,1-bis (2-methylphenyl) alkyne. The whole process requires fine operation and attention to detail to ensure the quality and yield of the product.
What are the precautions for using 1,1-bis (2-methylphenyl) guanidine?
1% 2C1-bis (2-methylbenzyl) ether should pay attention to the following things during use:
First, this substance has certain toxicity and irritation, and protective measures should be taken during operation.

Therefore, when using, wear suitable protective gloves, goggles and other equipment, and beware of direct contact.
Second, 1% 2C1-bis (2-methylbenzyl) ether is flammable. When storing and using, it should be kept away from open flame areas such as fire sources and heat sources to prevent fire. And it should be stored in a cool and well-ventilated place, away from direct sunlight, in case the temperature is too high to volatilize or cause other dangers.
Third, because of its chemical properties, when mixed with other chemical substances, or chemical reactions occur. Before mixing, be sure to understand its chemical properties and reactions with other substances in detail, and avoid blind mixing to prevent dangerous conditions such as harmful gases and explosions.
Fourth, after use, the remaining 1% 2C1-bis (2-methylbenzyl) ether and related waste should be properly disposed of in accordance with regulations. Do not dump at will to avoid pollution to the environment, and dispose in accordance with environmental protection requirements.
