1,1,1-trichloro-4-iodobutane, which belongs to the halogenated hydrocarbon class. Its physical properties are as follows:
- ** Properties **: Usually a colorless to light yellow liquid, it exists stably at room temperature and pressure, but may change slowly due to the activity of halogen atoms after contact with air or light, and the appearance may gradually become slightly cloudy.
- ** Boiling point **: Because the intermolecular force is mainly van der Waals force, and the presence of halogen atoms increases the molecular weight and enhances the intermolecular force, the boiling point is relatively high, probably in a certain temperature range (the specific value varies depending on the precise measurement conditions), so that it can be separated or purified by distillation at a specific temperature.
- ** Melting point **: The molecular arrangement has certain regularity, and it will solidify at a certain low temperature, showing a solid state. The melting point is also in the corresponding temperature range, which can be used as an important reference in the identification and separation process of substances.
- ** Solubility **: According to the principle of similarity compatibility, as a halogenated hydrocarbon, it has a certain solubility in polar organic solvents such as ethanol and acetone, because these solvents can form a certain interaction with 1,1,1-trichloro-4-iodobutane molecules; while the solubility in water is extremely small, because its molecular polarity is weak, and the force between water molecules is much smaller than the hydrogen bond force between water molecules, so it is difficult to dissolve in water.
- ** Density **: Due to the large relative atomic mass of halogen atoms, the density of this substance is higher than that of water, and it will be in the lower layer when it comes to operations such as liquid-liquid separation.

The chemical properties of 1,1,1-trifluoro-4-chlorobutene must be carefully observed. This compound contains fluorine, chlorine and other halogen elements. The fluorine atom has strong electronegativity and strong attraction to electrons when bonding, which makes the molecular structure unique.
From the perspective of bond energy, the carbon-fluorine bond energy is quite high, and a large amount of energy is required to break this bond, which stabilizes the molecule to a certain extent. However, it also contains carbon-chlorine bonds. Although the bond energy is not as good as that of carbon-fluorine bonds, it also affects the overall chemistry.
In common chemical environments, 1,1,1-trifluoro-4-chlorobutene has a certain resistance to general oxidation and reduction reactions. In case of strong nucleophilic reagents, carbon-chlorine bonds may be attacked, causing substitution reactions to occur. And in case of extreme conditions such as high temperature and strong radiation, the chemical bonds in the molecule may be excited and broken or rearranged, and the stability of chemical properties is also affected.
In summary, 1,1,1-trifluoro-4-chlorobutene has a certain chemical stability under conventional conditions, but under special conditions and the action of specific reagents, its chemical properties may change, and its absolute stability cannot be generalized.

To prepare 1,1,1-trichloro-4-bromobutane, the following ancient ideas can be considered:
First, bromobutane can be obtained by the addition of butene and hydrogen bromide. Take an appropriate amount of butene, place it in a clean container, slowly pass in hydrogen bromide gas, and under the action of appropriate temperature and catalyst, the two undergo an addition reaction. The double bond of butene is opened, and the bromine atom and hydrogen atom in the hydrogen bromide are added to both ends of the double bond to form bromobutane.
Then, the resulting bromobutane is substituted with chlorine gas. The bromobutane is moved into another reactor, and chlorine gas is introduced. Under the action of light or appropriate catalyst, the hydrogen atom on the ortho-carbon of the carbon connected to the bromine in the bromobutane is gradually replaced by the chlorine atom. After carefully controlling the reaction conditions and the amount of chlorine, three hydrogen atoms are replaced by chlorine atoms to obtain 1,1,1-trichloro-4-bromobutane.
Another way is to first replace butane with bromine under light to generate bromobutane. Choose pure butane, put an appropriate amount of bromine steam in the reaction vessel with sufficient light, and replace one hydrogen atom in the butane with a bromine atom to obtain bromobutane. Next, the bromobutane is reacted with chlorine gas under specific conditions, so that three chlorine atoms are introduced to the ortho-carbon of the bromolinked carbon. This process requires precise control of the reaction conditions, such as temperature, reactant ratio and reaction time, in order to efficiently produce the target product 1,1,1-trichloro-4-bromobutane. During operation, strict procedures must be followed, safety must be paid attention to, and the reactants and products must be properly handled to achieve the best preparation effect.

1% 2C1% 2C1-triene-4-chlorobutyronitrile rubber should pay attention to the following matters during storage and transportation:
First, it is related to the storage environment. This rubber should be stored in a cool, dry and well-ventilated place. Because the rubber is quite sensitive to temperature and humidity, high temperature and humid environment can easily cause its performance to deteriorate. If the temperature is too high, the rubber may become soft and sticky, affecting its physical properties; if the humidity is too high, it may cause mildew and other conditions, which may damage the quality. Therefore, the temperature of the storage place should be controlled within a specific range, and the humidity should also be maintained within a reasonable range.
Second, the storage method. It is necessary to avoid co-storage with various corrosive substances and strong oxidants. Due to its chemical properties, if it comes into contact with these substances, it is very likely that a chemical reaction will occur, causing the rubber to deteriorate. And when storing, it should be neatly stacked and not over-squeezed to prevent deformation and subsequent use.
Third, when transporting, protective measures should be taken. The transportation vehicle should be clean and dry to prevent external impurities from mixing into the rubber. During transportation, severe bumps and collisions should be avoided. Due to the relatively fragile texture of the rubber, strong vibration or collision may cause it to be damaged, broken, etc.
Fourth, regardless of storage or transportation, relevant safety norms and standards should be strictly followed. Transportation and storage personnel need to be fully aware of its characteristics and latent risks to ensure safety. In this way, 1% 2C1% 2C1-triene-4-chlorobutyronitrile rubber can be guaranteed to be of safe quality and stable performance during storage and transportation.
