What are the physical properties of 2-chloro Nitro Benzene?
2-Chloronitrobenzene is an organic compound. It has specific physical properties, which are described below.
In terms of its appearance, 2-chloronitrobenzene is a light yellow needle-like or rib-like crystal at room temperature. This color characteristic can be seen in ordinary observations. The light yellow appearance shows its unique color properties, and the needle-like or rib-like crystal shape gives it a specific microstructural characterization.
As for its melting point, it is about 32.5 ° C. This temperature is the critical temperature at which a substance changes from a solid state to a liquid state. When the ambient temperature rises to about 32.5 ° C, the solid-state structure of 2-chloronitrobenzene begins to disintegrate, and the intermolecular forces change, gradually transforming into a liquid state. The boiling point of
is about 245.5 ° C. The boiling point is the temperature at which the inside and surface of the liquid simultaneously vaporize violently. When the temperature reaches about 245.5 ° C, the liquid molecule of 2-chloronitrobenzene obtains enough energy to break free from the shackles of the liquid phase and transform into a gaseous state.
The density of 2-chloronitrobenzene is about 1.368g/cm ³. This density value indicates that the amount of substance contained in 2-chloronitrobenzene per unit volume. Compared with the density of water at 1g/cm ³, its density is higher, and this property determines its positional relationship when coexisting with liquids such as water.
Furthermore, its solubility is also an important physical property. 2-Chloronitrobenzene is slightly soluble in water, because water is a polar molecule, while the polarity of 2-chloronitrobenzene is relatively weak. According to the principle of similar miscibility, its solubility in water is limited. However, it is soluble in organic solvents such as ethanol, ether, and benzene, because these organic solvents are similar to the type of intermolecular forces of 2-chloronitrobenzene, and can be miscible with each other.
In addition, 2-chloronitrobenzene has a certain volatility, which can evaporate slowly in the air, and because its molecular structure contains functional groups such as chlorine and nitro, it has a special odor. Although it is difficult to describe exactly, people can sense its unique smell by smell.

What are the chemical properties of 2-chloro Nitro Benzene?
2-Chloronitrobenzene is one of the organic compounds. It is active and has a variety of chemical characteristics.
The first to bear the brunt is the reaction characteristics of halogenated aromatics. The chlorine atoms in 2-chloronitrobenzene can leave due to nucleophilic substitution. Because the electron cloud density on the benzene ring is reduced by the influence of nitro groups, the positive electricity of the carbon atoms attached to the chlorine atoms is enhanced, and it is more susceptible to attack by nucleophilic reagents. Common nucleophilic reagents, such as hydroxyl anions, amino anions, etc., can react with it. Treat 2-chloronitrobenzene with an aqueous solution of sodium hydroxide, and after nucleophilic substitution, the chlorine atoms are replaced by hydroxyl groups to generate 2-nitrophenol; if treated with ammonia water, 2-nitroaniline can
Furthermore, the nitro group on the benzene ring endows it with reducing properties. Nitro groups can be reduced under specific conditions, and reducing agents such as iron and hydrochloric acid, tin and hydrochloric acid are commonly used. Under the action of iron and hydrochloric acid, the nitro group of 2-chloronitrobenzene can be gradually reduced to an amino group to obtain 2-chloroaniline. This reaction is widely used in organic synthesis, because the amino group can further derive many different functional groups.
In addition, although the electron cloud density of the benzene ring of 2-chloronitrobenzene decreases due to the influence of nitro and chlorine atoms, electrophilic substitution reactions can still occur. However, because both nitro and chlorine atoms are blunt groups, the reactivity is lower than that of benzene. And the localization effects of the two are different. Nitro is the meta-site locator, and chlorine atom is the o-para-site locator. Under the combined influence, the newly introduced substituents mainly enter the meta-site. For example, under the mixed acid of concentrated sulfuric acid and concentrated nitric acid, nitrification can occur to generate 2-chloro-3,5-dinitrobenzene.
In summary, the interaction of 2-chloronitrophenyl chloride atom, nitro group and benzene ring presents various chemical properties such as nucleophilic substitution, nitro reduction, and electrophilic substitution, which occupy an important position in the field of organic synthesis.

What are the production methods of 2-chloro Nitro Benzene?
2-Chloronitrobenzene, organic compounds are also industrially prepared by many methods, and each has its own reasons. The details are as follows:
First, the nitrification method is also. With o-chloroaniline as the starting material, it is prepared by two steps of diazotization and nitrification. First, the o-chloroaniline and sodium nitrite are reacted in an acidic medium by diazotization to obtain diazonium salts. After the diazotic salt is co-placed with nitric acid to make it nitrified, then 2-chloronitrobenzene is obtained. The reaction conditions are easy to control, but the steps are complicated, and the diazotization reaction requires strict control of temperature and pH, otherwise accidents are prone to occur.
Second, the halogenation method. Using nitrobenzene as the substrate, the target product is obtained by halogenation. In a suitable catalyst, nitrobenzene meets with chlorine gas, and the halogenation reaction begins. The chlorine atom enters the ortho-position of nitrobenzene to produce 2-chloronitrobenzene. This raw material is easy to obtain, but the reaction selectivity is not good. It is often obtained from the mixture of o, m, and p-chlorinated nitrobenzene, which makes it difficult to separate and purify.
Third, palladium catalytic coupling method. Halogenated benzene and nitroaromatic hydrocarbons are used as raw materials and are coupled and reacted with the help of palladium catalyst. This process has high activity and selectivity of palladium catalyst, and can accurately obtain 2-chloronitrobenzene, and the reaction conditions are mild. However, palladium is a precious metal, and its high cost limits its large-scale use.
Fourth, electrochemical synthesis method. 2-Chloronitrobenzene is obtained by redox reaction on the surface of the electrode by electrochemical means. This way is green and environmentally friendly, does not require a large amount of oxidants and reducing agents, and the reaction conditions are mild. However, the current technology is not mature, and large-scale production still needs to be further explored.
All preparation methods have advantages and disadvantages. In actual production, the appropriate method should be carefully selected according to various factors such as the availability of raw materials, cost considerations, product purity requirements and environmental impact.

2-Chloronitrobenzene is a chemical substance. During storage and transportation, many matters must be observed.
Its properties are dangerous. When storing, the conditions of the warehouse should be the first priority. The warehouse should be selected in a cool and ventilated place, away from fire and heat sources. Because the substance is prone to danger due to heat, temperature control is crucial. The storage temperature should not exceed 30 ° C.
Furthermore, when storing, it should be stored in categories. 2-Chloronitrobenzene should not be mixed with oxidants, edible chemicals, etc. It is dangerous if it encounters with oxidants or causes violent chemical reactions.
Packaging should not be ignored. The packaging must be in good condition and sealed to prevent leakage. When handling, it needs to be loaded and unloaded lightly. Do not collide or drag, so as not to damage the packaging and cause material leakage.
During transportation, also pay extra attention. Transportation vehicles should be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Driving routes should avoid residential areas and densely populated areas. During transportation, ensure that the container does not leak, collapse, fall or damage.
In the event of a leak, emergency responders must wear protective equipment, quickly evacuate the personnel in the leaked contaminated area to a safe place, and isolate and strictly restrict access. Do not let leaks come into contact with flammable substances to prevent the risk of fire. Small leaks can be absorbed by inert materials such as sand and vermiculite; large leaks require construction of embankments or excavation for containment, transfer to a tanker or dedicated collector by pump, and recycling or transportation to a waste treatment site for disposal.
