What are the physical properties of 1,1 '- (chloromethylene) bisbenzene
1%2C1%27-%28chloromethylene%29bisbenzene, that is, 1,1 '- (chloromethylene) dibenzene, also known as benzyl chloride. The physical properties of this substance are quite unique and are closely related to many practical applications.
Looking at its properties, under normal conditions, 1,1' - (chloromethylene) dibenzene is a colorless to yellowish transparent liquid. Under sunlight, it often refracts, as if there is a hidden light flowing. Its smell is pungent and strong, and it smells uncomfortably, as if it is a warning to contacts to be cautious.
When it comes to volatility, this substance is highly volatile. In a normal temperature environment, it is easy to quietly transform from liquid to gaseous state and escape in the surrounding space. This characteristic not only gives it the advantage of participating in the reaction quickly in some reaction systems, but also increases the difficulty of environmental control during storage and use.
In terms of boiling point, the boiling point of 1,1 '- (chloromethylene) dibenzene is about 205-207 ° C. At this temperature, the substance gradually changes from liquid to gaseous state, realizing the phase transition. This boiling point data provides key parameters for its separation, purification and other process operations.
Above the density, its density is greater than that of water, about 1.102 g/cm ³. When mixed with water, it will sink to the bottom of the water, forming an obvious stratification phenomenon. This characteristic can be used in the operation process involving liquid-liquid separation.
Solubility is also one of the important physical properties. 1,1 '- (chloromethylene) dibenzene is insoluble in water, just like two kinds of substances that are incompatible with water. However, in organic solvents, such as ethanol, ether, benzene, etc., it shows good solubility and can dissolve with it to form a uniform and stable solution system. This solubility characteristic provides a basis for the selection of suitable reaction media and solvents in the fields of organic synthesis and material preparation.
To sum up, the many physical properties of 1,1 '- (chloromethylene) dibenzene, from properties, volatility, boiling point, density to solubility, have their own characteristics and are interrelated. They all play an important role in the research and application of chemical, materials, medicine and other fields. Only by accurately grasping and rationally applying them can they better serve the actual production and scientific research.

Is 1,1 '- (chloromethylene) bisbenzene chemically stable?
1%2C1%27-%28chloromethylene%29bisbenzene is 1,1 '- (chloromethylene) dibenzene, which is chemically unstable. Its chloromethylene structure, chlorine has strong electronegativity, causing high polarity of carbon-chlorine bonds, prone to heterocracking, leading to nucleophilic substitution reactions.
In this molecule, the benzene ring is an electron-rich system, which has an impact on the distribution of chloromethylene electron clouds. Due to the activity of chloromethylene, it is easy to react with nucleophilic reagents such as alcohols and amines. When exposed to water, water molecules can be used as nucleophiles to attack chloromethylene carbon, causing hydrolysis reactions, resulting in corresponding hydroxy compounds and hydrogen chloride.
From the perspective of stability, the carbon-chlorine bond energy is limited, and under the action of light, heat or specific catalysts, the easily broken bond initiates a series Even without external reagents, it may gradually decompose or transform due to intramolecular interactions and environmental factors. In summary, 1,1 '- (chloromethylene) dibenzene is chemically unstable, and specific conditions are required for storage and use to prevent it from deteriorating due to reactions.

What is the production method of 1,1 '- (chloromethylene) bisbenzene
1%2C1%27-%28chloromethylene%29bisbenzene is 1,1 '- (chloromethylene) dibenzene, often referred to as dichlorobenzyl. Its preparation method is as follows:
In the past, the method of preparing dichlorobenzyl used toluene as the starting material. First, toluene is substituted with chlorine under light conditions. Because light can initiate the generation of chlorine radicals, this free radical reacts with the methyl group of toluene and gradually replaces the hydrogen atom on it.
In the initial stage, one of the hydrogen atoms on the methyl group of toluene is replaced by a chlorine atom to form benzyl chloride. During the reaction, attention must be paid to controlling the reaction conditions, such as light intensity, chlorine gas penetration rate, reaction temperature, etc. If the light is too strong, the chlorine gas is passed too fast or the temperature is too high, it is easy to cause excessive reaction.
Then, benzyl chloride can be further reacted with chlorine gas, and another hydrogen atom on the methyl group is replaced by a chlorine atom to obtain benzyl dichloride. This step also requires fine regulation of conditions to improve the yield and purity of benzyl dichloride.
There is also a method of reacting benzene with formaldehyde and hydrogen chloride as raw materials to prepare benzyl dichloride in the presence of a specific catalyst. The catalyst can accelerate the reaction process and reduce the activation energy required for the reaction. However, this method requires quite high reaction equipment and operation, and the purity of the raw material also has a great impact on the reaction.
The process of preparing dichlorobenzyl requires close monitoring of the reaction process. By means of analytical methods such as gas chromatography, the composition and content of the product can be known in real time, so that the reaction conditions can be adjusted in time to obtain high-purity dichlorobenzyl products.

What are the environmental effects of 1,1 '- (chloromethylene) bisbenzene
1%2C1%27-%28chloromethylene%29bisbenzene is 1,1 '- (chloromethylene) dibenzene, which has a significant impact on the environment.
The first one to bear the brunt is the impact on the air. If this substance escapes in the atmosphere, it is volatile or can form organic aerosols, which in turn affects atmospheric visibility. And under conditions such as light, it may participate in complex photochemical reactions, generate secondary pollutants such as ozone, aggravate the formation of photochemical smog, endanger air quality, and pose a threat to human respiratory health.
Furthermore, it is related to the aquatic ecological environment. If 1,1' - (chloromethylene) dibenzene flows into water, it is insoluble in water and fat-soluble, and is easily ingested by aquatic organisms and enriched in the body. In this way, it may interfere with the normal physiological metabolism of aquatic organisms, affecting their reproduction, growth and even survival. In the long run, it may cause the structure and function of aquatic ecosystems to be disrupted, and biodiversity will be damaged.
As for the soil environment, once this substance enters the soil, it will adsorb on the surface of soil particles, affecting the physical and chemical properties of the soil. It may inhibit the activity of soil microorganisms, hinder the material circulation and energy conversion in the soil, and then have adverse effects on vegetation growth, affecting crop yield and quality.
In addition, 1,1 '- (chloromethylene) biphenyl degrades slowly in the environment, can be retained for a long time, and is transmitted and enriched through the food chain, eventually endangering human health, such as causing liver, kidney and other organ diseases, or teratogenic and carcinogenic risk. Therefore, its release and dissemination in the environment should be strictly controlled to ensure the safety of the ecological environment.
