What is the chemistry of O-chlorobenzenecarboxyaldehyde?
O-chlorobenzaldehyde is also an organic compound. It has the versatility of aromatic alaldehyde, is lively and good at responding to various substances.
First of all, its physical rationality, o-chlorobenzaldehyde is a colorless to slightly yellow liquid with a special aroma. The boiling point is about 215 to 217 degrees, the density is greater than that of water, insoluble in water, but soluble in organic solvents such as alcohols and ethers. Because of its molecular structure, it contains a hydrophobic benzene ring and an aldehyde group of a hydrophilic solvent.
As for its chemical properties, the aldehyde group is its active center. Oxidation reaction can occur. If it encounters a strong oxidizing agent, the aldehyde group can be oxidized to a carboxyl group to obtain o-chlorobenzoic acid; if it encounters a weak oxidizing agent such as Torun reagent, it will form o-chlorobenzoate and silver mirror. This is a characteristic reaction of aldehyde groups.
can also undergo a reduction reaction. With an appropriate reducing agent, the aldehyde group can be reduced to a hydroxyl group to obtain o-chlorobenzyl alcohol. The addition reaction of
is also an important property. The carbon-oxygen double bond of the aldehyde group can be added to compounds containing active hydrogen, such as with alcohols to form hemiacetals and acetals; and with hydrocyanic acid to obtain o-chlorobenzyl cyanols. This reaction is often used in organic synthesis to increase carbon chains and introduce new functional groups.

What are O-chlorobenzenecarboxyaldehyde synthesis methods?
O-chlorobenzaldehyde is a commonly used raw material in organic synthesis. There are many ways to synthesize it.
First, it is obtained by oxidation with o-chlorotoluene as the starting material. Among them, chemical oxidants can be used, such as chromic acid, potassium permanganate and the like. However, many of these oxidants are highly corrosive, and the waste treatment after the reaction is quite difficult. Catalytic oxidation can also be used. A suitable catalyst, such as a transition metal oxide, can be selected to oxidize o-chlorotoluene to O-chlorobenzaldehyde under a certain temperature, pressure and oxygen atmosphere. This catalytic oxidation method is relatively green and environmentally friendly, and has good selectivity.
Second, it is obtained by reduction of o-chlorobenzoic acid. Lithium aluminum hydride and sodium borohydride are often used as reducing agents. Lithium aluminum hydride has strong reducing power, and it is easy to react violently in water, so it needs strict anhydrous operation; sodium borohydride is relatively mild and easy to operate. After this reduction reaction, the carboxyl group of o-chlorobenzoic acid can be converted into an aldehyde group to obtain O-chlorobenzaldehyde.
Third, o-chlorobenzoyl chloride is used as raw material and prepared by Rosenmund reduction reaction. O-chlorobenzaldehyde can be obtained by reducing o-chlorobenzoyl chloride with hydrogen in the presence of palladium catalyst and quinoline-thioquinoline inhibitor. This reaction condition is mild and the selectivity to aldehyde groups is quite high, which can effectively avoid excessive reduction to form alcohol by-products.
All methods of synthesis have their own advantages and disadvantages. In practical applications, careful choices should be made based on factors such as the availability of raw materials, cost, reaction conditions, and product purity.

O-chlorobenzenecarboxyaldehyde need to pay attention to when storing and transporting
O-chlorobenzaldehyde is an organic compound. When storing and transporting it, the following numbers should be paid attention to:
First, when storing, it should be placed in a cool and ventilated warehouse. Because of its volatility, high temperature will cause volatilization to intensify, and may cause chemical reactions, so a cool environment is quite important. Good ventilation can prevent its gas accumulation and reduce safety hazards.
Second, it is necessary to keep away from fire and heat sources. O-chlorobenzaldehyde is a flammable substance. It is very easy to burn in case of open flame and hot topic. It will cause fire if it is not careful, so it must be kept at a safe distance from fire and heat sources.
Third, it should be stored separately from oxidants, acids and alkalis, and should not be stored together.
Fourth, the storage area should be equipped with suitable materials to contain leaks. In case of leakage, it can be dealt with in a timely and effective manner to reduce the harm to the environment and people.
Fifth, when transporting, make sure that the container does not leak, collapse, fall, or damage. Because it is a liquid, it is easy to leak if the container is damaged.
Sixth, during transportation, it should be protected from exposure to the sun, rain, and high temperature. Exposure to sunlight and high temperature environment will cause its volatilization to accelerate, and even cause dangerous reactions. Seventh, the trough (tank) car used during transportation should have a grounding chain, and holes can be set in the trough to baffle to reduce the static electricity generated by shock. O-chlorobenzaldehyde is an organic liquid, which is prone to static electricity during vibration during transportation, static electricity accumulation or fire or even explosion. The grounding chain and hole baffle can effectively remove static electricity.

O-chlorobenzenecarboxyaldehyde impact on the environment and people
O-chlorobenzaldehyde (O-chlorobenzenecarboxyaldehyde) is also an organic compound. Its impact on the environment and the human body cannot be ignored.
In the environment, if this substance is released in nature, it can exist in water, soil and atmosphere. In water, or affect aquatic organisms. Its chemical properties or cause physiological disorders in aquatic organisms, hindering their growth, reproduction, and even death. In the soil, or change the chemical properties of the soil, affect the activities of soil microorganisms, and then endanger the growth and development of plant roots. If scattered in the atmosphere, or photochemical reactions with other substances, generate harmful secondary pollutants, affecting air quality.
As for the human body, O-chlorobenzaldehyde is irritating. If inhaled through the respiratory tract, it can irritate the mucosa of the respiratory tract, causing cough, asthma, breathing difficulties and other diseases. If exposed to the skin, it can cause redness, swelling, itching, and allergies to the skin. Accidentally entering the eyes can cause great damage to the eyes, or damage the vision. Long-term exposure and high exposure may pose a potential carcinogenic risk, because the substance may interfere with the normal metabolism of human cells and the stability of genetic materials.
