1-Iodo-3-fluoropropane, Chinese name 1-iodo-3-fluoropropane, is an organic compound. Its physical properties are crucial and are related to many chemical processes and practical applications.
This compound is a colorless to light yellow liquid under normal conditions, with a special odor. Looking at its color and state, it is caused by molecular structure and interaction. The presence of iodine and fluorine atoms in the molecule affects the intermolecular forces, which in turn determines its liquid state at room temperature and pressure.
The boiling point of 1-iodo-3-fluoropropane is about 144-146 ° C. The boiling point is restricted by the intermolecular forces. The electronegativity difference between iodine and fluorine atoms makes the molecules exhibit polarity, enhances the intermolecular attraction, and increases the boiling point. This boiling point characteristic is an important consideration in chemical operations such as distillation and separation.
Its density is about 1.82 g/mL. The density depends on the molecular weight and the way of molecular accumulation. The relative mass of iodine atoms increases the overall molecular weight, resulting in a higher density than that of common organic solvents. In mixed systems, this density characteristic can be used for operations such as stratification and separation.
In terms of solubility, 1-iodo-3-fluoropropane is slightly soluble in water, but easily soluble in organic solvents such as ethanol, ether, and acetone. This is because water is a polar solvent, and although the compound has a certain polarity, the proportion of organic groups is relatively large. It follows the principle of "similar miscibility" and prefers to dissolve with organic solvents. This solubility characteristic is the basis for selecting suitable solvents in the process of organic synthesis and extraction.
The vapor pressure of 1-iodo-3-fluoropropane is low, indicating that its volatility is relatively weak. This characteristic is of great significance during storage and use. Due to weak volatility, it reduces its diffusion in the air and reduces safety risks.
In conclusion, the physical properties of 1-iodo-3-fluoropropane, such as physical state, boiling point, density, solubility and vapor pressure, play a decisive role in its application in organic synthesis, chemical production and related research fields, and need to be fully considered in research and use.

1-Iodo-3-fluoropropane is also an organic compound. Its chemical properties are relatively unstable.
In this compound, the existence of iodine atoms and fluorine atoms has a great impact on its properties. The iodine atom has a large radius and the carbon-iodine bond energy is relatively small, which is prone to heterocracking, so that the iodine atom of this compound is easily replaced by nucleophilic reagents in the nucleophilic substitution reaction. Nucleophilic substitution reactions are one of the common types of organic chemistry, and 1-iodo-3-fluoropropane often exhibits activity in this reaction.
Furthermore, fluorine atoms have strong electronegativity, and their existence changes the distribution of molecular electron clouds. Although the carbon-fluorine bond has high energy and is not easy to break, it has a significant impact on the adjacent carbon-hydrogen bond, so that the compound can participate in specific reactions due to the change of hydrogen atom activity at specific positions in some reactions.
In addition, the stability of 1-iodo-3-fluoropropane is affected by environmental factors due to the different electronic effects of iodine and fluorine atoms. When exposed to heat, light or specific catalysts, the internal energy of the molecule changes, triggering chemical bond changes, or causing decomposition, rearrangement and other reactions.
When storing and using 1-iodo-3-fluoropropane, due to its unstable chemical properties, it needs to be handled with caution. It should be placed in a low temperature, dark and dry place to prevent its properties from changing due to environmental factors and unnecessary chemical reactions.

There are several methods for synthesizing 1-iodine-3-fluoropropane.
First, 3-fluoro-1-propanol is used as the starting material. First, it is reacted with p-toluenesulfonyl chloride in the presence of basic reagents such as pyridine to generate 3-fluoropropyl p-toluenesulfonate. In this step, the basic reagent can neutralize the generated hydrogen chloride and push the reaction forward. Subsequently, the generated sulfonate is heated with sodium iodide in a solvent such as acetone, and the sulfonate group is replaced by iodine ion to obtain 1-iodine-3-fluoropropane. In this path, p-toluenesulfonyl chloride can convert the hydroxyl group into a sulfonate group that is easier to leave, and the iodine ion in sodium iodide has strong nucleophilicity, which is conducive to the substitution reaction.
Second, 1,3-dihalopropane is used as the raw material. If the starting material is 1,3-dichloropropane, it can be reacted with potassium fluoride in a polar aprotic solvent (such as DMF) first, and the chlorine atom is replaced by the fluorine atom to form 3-chloro-1-fluoropropane. After that, 3-chloro-1-fluoropropane is reacted with sodium iodide in an appropriate solvent (such as acetone), and the chlorine atom is replaced by the iodine atom to obtain the target product 1-iodine-3-fluoropropane. This synthesis route is carried out in two steps. The activities of different halogen atoms are different, and the desired halogen atoms can be gradually introduced by using this property.
Third, propylene is used as the raw material. First, the addition reaction of propylene with N-fluorobisphenylsulfonamide (NFSI) occurs under appropriate conditions to generate 3-fluoro-1-bromopropane. After that, 3-fluoro-1-bromopropane is reacted with sodium iodide in a solvent such as acetone, and the bromine atom is replaced by the iodine atom, and finally 1-iodine-3-fluoropropane is obtained. This route starts with common olefins and gradually builds the target molecular structure through addition and substitution reactions.

1-Iodo-3-fluoropropane is an organic compound. During storage and transportation, many things need to be paid attention to to ensure safety.
First, when storing, find a cool, dry and well-ventilated place. This compound is easy to decompose when heated, and the high temperature environment may cause danger, so it should avoid direct sunlight and heat sources. If the storage temperature is too high, it may cause chemical reactions and even cause serious accidents such as explosions.
Second, because of its certain toxicity and irritation, the storage place must be kept away from crowded areas and food, beverages and other items. Significant warning signs should be set up to prevent others from accidentally touching and misusing. At the same time, the entry and exit of personnel in the storage place should be strictly controlled, and only professionals should be allowed to enter.
Third, during transportation, choose suitable packaging materials. This compound may be corrosive to packaging materials, and packaging that can resist its corrosion and has good sealing must be used to prevent leakage. The outside of the package should also be clearly marked with relevant information, such as name, danger, etc.
Fourth, the transportation vehicle should be equipped with good ventilation and temperature control devices. Ensure that the temperature is suitable during transportation, avoid bumps and vibrations, and prevent the leakage of compounds due to package damage. In the event of a leak, emergency measures should be taken immediately, evacuate the surrounding personnel, strictly prohibit the source of fire from approaching, and quickly clean up the leak to prevent pollution of the environment and endanger human health.
In short, 1-iodo-3-fluoropropane must be stored and transported in strict accordance with relevant safety regulations, and must not be taken lightly, so as to ensure the safety of personnel and the environment is not damaged.
