What are the physical properties of O-nitrochlorobenzene?
O-nitrochlorobenzene is also an organic compound. It has specific physical properties. Looking at its color, it often shows a light yellow crystalline shape, and it has a crystal clear feeling. Smell it, emit a special smell, although it is not pungent and intolerable, it also has its unique smell. In terms of its melting point, it is about 32.5 ° C. When the temperature reaches this point, it gradually melts from a solid state to a liquid state, just like ice and snow melting when they are warm. The boiling point is 245.5 ° C. At this high temperature, it takes on a boiling state and turns into a gaseous state and rises. Its density is also an important physical property, about 1.368g/cm ³, which is heavier than water. If placed in water, it will sink to the bottom of the water. And slightly soluble in water, like a shy guest in water, only a small amount of blending. However, in organic solvents such as ethanol and ether, it can be better miscible, just like a fish entering water, free and happy. And because of its physical properties, it is used in many fields of chemical industry. For example, in industrial preparations such as dyes and medicine, it is often an important raw material, just like masonry in Guangsha, it is indispensable.
What is the chemistry of O-nitrochlorobenzene?
O-nitrochlorobenzene is also an organic compound. Its color is light yellow, in the shape of needle-like crystals, and has a pungent smell. In terms of its physical and chemical properties, the melting point is 32.5 ° C, and the boiling point is 245.5 ° C. Under normal temperature and pressure, the properties are relatively stable. Slightly soluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. The chemical properties of this compound are active, and there are both nitro and chlorine atoms connected to its benzene ring. Nitro is a strong electron-absorbing group, which can reduce the electron cloud density of the benzene ring and increase the difficulty of electrophilic substitution reaction; while chlorine atoms are also electron-absorbing groups, they can form p-π conjugate with the benzene ring, and under specific conditions, nucleophilic substitution reaction can occur. In the nucleophilic substitution reaction, the hydroxyl group, amino group and other nucleophilic reagents can attack the carbon atom connected to the chlorine atom, and the chlorine atom leaves to form the corresponding substitution product. For example, when co-heated with sodium hydroxide solution, the chlorine atom can be replaced by the hydroxyl group to obtain o-nitrophenol. O-nitrochlorobenzene can also participate in the reduction reaction. The nitro group can be gradually reduced, and the nitroso group can be obtained first, and then the amino group can be obtained to form o-chloroaniline and other products. And because of its active chemical properties, it is widely used in the field of organic synthesis and is often an important intermediate in the synthesis of fine chemicals such as
What are O-nitrochlorobenzene production methods?
O-nitrochlorobenzene, as well as organic compounds, is widely used in industrial production. There are two common methods for its preparation. One is the nitrification method. This is to use chlorobenzene as a raw material to react with mixed acids (mixtures of nitric acid and sulfuric acid). Under the catalysis of sulfuric acid, nitric acid dissociates nitro-positive ions (NO ²). This ion has strong electrophilicity and attacks the benzene ring of chlorobenzene, replacing the hydrogen atom on it, and then generates O-nitrochlorobenzene. In the reaction process, the work of sulfuric acid is to enhance the acidity of nitric acid, promote it to form nitro-positive ions, and absorb the water generated by the reaction, so that the balance moves in the direction of product formation. This process requires precise temperature control, and the cap temperature affects the isomer ratio of the product. Generally, at low temperatures, the yield of O-nitrochlorobenzene is higher. The second is halogenation. First, nitrobenzene is used as the starting material, and chlorine atoms are introduced through halogenation reaction. Usually chlorine is used as the halogenating agent. In the presence of a specific catalyst, the chlorine molecule is affected by the catalyst and dissociates into a chlorine radical (Cl ·). Its activity is abnormal. It undergoes a radical substitution reaction with the benzene ring of nitrobenzene to obtain O-nitrochlorobenzene. In the halogenation reaction, the choice of catalyst is crucial, and its activity and selectivity affect the formation of the product. Under different catalyst conditions, the reaction rate and product distribution are different. These two methods have their own advantages and disadvantages. During industrial production, it is necessary to weigh and choose according to the actual situation, such as raw material cost, product purity requirements, and equipment conditions.
O-nitrochlorobenzene What are the precautions during storage and transportation?
O-nitrochlorobenzene is a toxic and dangerous chemical. When storing and transporting, many important things must be paid attention to. First words storage, must look for a cool, well ventilated warehouse. This is because O-nitrochlorobenzene is easily dangerous when heated, and under high temperature, there may be a risk of decomposition or explosion. The temperature of the warehouse should be controlled in a suitable range, not too high. And keep away from fire and heat sources. If an open flame is close, it will cause disaster. It should be stored separately from oxidizing agents, reducing agents, alkalis, etc., and must not be mixed. Because of its active chemical properties, contact with other substances, or react violently. At the same time, the warehouse must be equipped with suitable materials to contain leaks in case of leakage, which can be dealt with in time to avoid greater harm. As for transportation, make sure that the packaging is complete and the loading is safe before transportation. If the packaging is damaged, O-nitrochlorobenzene leaks, which is extremely harmful. During transportation, the speed should not be too fast, nor should it be braked suddenly to prevent vibration and impact from causing damage to the packaging. Transportation vehicles should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. If there is an emergency on the way, it can be dealt with in time. And when transporting, follow the specified route and do not stop in densely populated areas and traffic arteries. In the event of a leak, drivers and passengers should quickly evacuate to a safe area, isolate the scene, and strictly restrict access. Emergency responders must wear full-face masks and gas suits to handle leaks with caution, or use inert materials such as sand and vermiculite to absorb them before proper disposal.
