What are the physical properties of P-chloronitrosobenzene?
P-chloro-nitrosobenzene is an organic compound. Its physical properties are quite unique.
Looking at its properties, it is mostly in a solid state at room temperature, which is caused by intermolecular forces. In terms of color, it often appears light yellow, which is derived from the absorption and reflection characteristics of its molecular structure.
When it comes to the melting point, its melting point is about [X] ° C, and its boiling point is about [X] ° C. The values of melting point and boiling point are determined by the strength of the chemical bonds within the molecule and the intermolecular forces. The chlorine atom in the molecule is connected to the benzene ring, and the nitroso group is also in the para-position. This structure makes the intermolecular forces present a specific intensity, which in turn affects the melting boiling point.
Furthermore, its solubility also has characteristics. In organic solvents, such as ethanol, ether, etc., there is a certain solubility, which is due to the principle of "similarity and miscibility". The structure of organic molecules is similar to that of organic solvents, and a certain force can be formed between molecules, so it is soluble; however, in water, the solubility is very small, because it is an organic compound, the force between water molecules is weak, and the presence of benzene rings, chlorine atoms and nitroso groups makes its molecular polarity insufficient to form a good miscibility system with water.
And its density is higher than that of water, which is due to the type and close arrangement of atoms in the molecule. In P-chloro-nitrosobenzene molecule, the relative atomic mass of chlorine atom is larger, and the structure of benzene ring is relatively compact, which makes its unit volume mass greater than that of water.
What are P-chloronitrosobenzene synthesis methods?
The method of making p-chloronitrobenzene has been explored by chemists in the past. One method is to use p-chloroaniline as the starting material, first react with sodium nitrite and hydrochloric acid, and carry out diazotization reaction in a low temperature environment. The reaction formula is roughly as follows: p-chloroaniline is mixed with sodium nitrite and hydrochloric acid to obtain p-chloro diazonium salt. This step requires temperature control to prevent the decomposition of diazonium salt.
Then, the p-chloro diazonium salt meets the reducing agent such as stannous chloride, which can convert the diazonium group into a nitroso group, and then obtain p-chloronitrobenzene.
Another method is to use p-chlorophenol as the starting material. First, p-chlorophenol is reacted with nitrous acid. After specific conditions and steps, nitroso groups can be introduced into the para-position of the benzene ring, and then p-chloro-nitrosobenzene can be obtained. However, in this process, attention should be paid to the control of reaction conditions, such as temperature, pH, etc., which have a great impact on the purity and yield of the product.
Or those who use other compounds as starting materials can eventually achieve the purpose of preparing p-chloro-nitrosobenzene through multi-step transformation. However, no matter what method, it is necessary to study the reaction mechanism and carefully control the reaction conditions to obtain p-chloro-nitrosobenzene with higher yield and purity.
