What are the physical properties of iodooctadecane?

1-Iodooctadecane, that is, 1-iodostadecane, is an organic compound. Its physical properties are as follows:
In appearance, it usually shows a colorless to light yellow liquid state, with a pure texture and no visible impurities. This is due to its long carbon chain in the molecular structure and moderate intermolecular forces, which maintain a liquid state at room temperature.
The boiling point is quite high, about 237 ° C (1.33kPa). Due to the large molecular weight and long carbon chain of this substance, there is a strong van der Waals force between molecules. To make the molecules break free from each other and become gaseous, more energy needs to be supplied, so the boiling point is high. The melting point of
is 28-30 ° C. Under this temperature range, the thermal motion energy of molecules decreases, the orderly arrangement between molecules is enhanced, and the liquid state is converted to a solid state. The density of
is about 1.05g/cm ³, which is slightly higher than the density of water. Due to the large relative atomic weight of iodine atoms in the molecule, its unit volume mass is larger.
In terms of solubility, it is difficult to dissolve in water. Because it is a non-polar organic compound, and water is a polar solvent, according to the principle of "similar miscibility", the polarity difference between the two is large, and the interaction force is weak, so it is difficult to dissolve. However, it is soluble in many organic solvents, such as ether, benzene, chloroform, etc. Because these organic solvents are also non-polar or weakly polar, they can be miscible with each other due to the intermolecular force of 1-iodostadecane.
In addition, 1-iodostadecane is volatile to a certain extent, but due to the large intermolecular force, the volatility is relatively weak. At room temperature and pressure, it can evaporate slowly in the air, and when the temperature rises, the volatilization rate accelerates.

1-What are the chemical properties of iodooctadecane?

1-Iodooctadecane, or 1-iodooctadecane, has unique chemical properties. It is an organic halide containing an iodine atom and an octadecane straight-chain alkyl group.
In terms of physical properties, it is mostly liquid at room temperature. Due to the existence of long-chain alkyl groups, it has certain hydrophobicity. It is insoluble in water and can be soluble in common organic solvents such as ether and chloroform. Its molecular weight is large, the boiling point is relatively high, and it is due to strong intermolecular forces.
In terms of chemical properties, the activity of iodine atoms allows 1-iodooctadecane to participate in many reactions. In the nucleophilic substitution reaction, the iodine atom is easily replaced by the nucleophilic reagent. If it reacts with sodium alcohol, the corresponding ether compound can be formed; when reacted with sodium cyanide, the cyanyl group replaces the iodine atom to obtain the octadecarbon compound containing the cyanide group. The product can be further hydrolyzed or reduced to obtain other organic compounds.
In addition, 1-iodostadecane can also participate in the elimination reaction. Under the action of a strong base, the iodine atom is removed from the hydrogen atom on the adjacent carbon atom to form a carbon-carbon double bond to obtain the octadecarbon-containing olefin compound. This olefin can be
Due to the iodine-containing atom, 1-iodostadecane is widely used in the field of organic synthesis. It can be used as an intermediate to synthesize organic compounds with different functional groups and structures, providing an important basis for the research and practical application of organic synthetic chemistry.

1-What are the synthesis methods of iodooctadecane?

There are various ways to synthesize 1-iodooctadecane. One is to react with octadecanol and an iodizing reagent. Take octadecanol and place it in a reactor, and add an iodizing reagent, such as hydrogen iodide or phosphorus triiodide. If hydrogen iodide is used, under a suitable temperature and pressure, the two begin a substitution reaction. The hydroxyl group of the alcohol is replaced by an iodine atom, and then 1-iodooctadecane is obtained. The reaction temperature and time should be controlled to prevent side reactions. If the temperature is too high, it may cause the elimination of the reaction, resulting in olefin impurities; if the time is too long, there may be a risk of excessive iodization.
Another method is to replace octadecyl halides with i Take octadecyl chloride or bromine and mix it with sodium iodide or potassium iodide in an organic solvent. Common solvents are acetone, acetonitrile, etc. The activity of halogen atoms is different. The activity of chlorine is slightly lower, and the reaction may require a slightly higher temperature and a longer time; the activity of bromine is higher, and the reaction is easier. In this reaction, the solvent is very important, and it is necessary to be able to dissolve the reactants and not react with both, so as to facilitate the reaction.
In addition, starting with octadecane, halogenated octadecane is first obtained, and then reacted with iodizing reagents to obtain 1-iodooctadecane. During halogenation, chlorine gas or bromine can be used, and the free radical substitution reaction can be carried out under light or initiator to obtain halogenated octadec After changing with iodizing reagent according to the previous method, the target product was obtained. However, the selectivity of free radical reaction is not good, or a variety of halogenated isomers are generated, and it is necessary to separate and purify well to obtain pure 1-iodooctadecane.
