What are the physical properties of 3,4-diaminobenzenesulfonic acid?
Diaminobenzoic acid, that is, 3,4-diaminobenzoic acid, has the following physical properties:
Its appearance is often white to light yellow crystalline powder. This shape is easy to observe and distinguish, and in various experimental and industrial scenarios, this appearance feature can be used as a preliminary basis for judgment. Its melting point is between 175 and 177 degrees Celsius, and its melting point characteristics are of great significance in the identification and purification of substances. Melted at a specific temperature, it can be distinguished from other substances with different melting points for the purpose of separation or identification.
Diaminobenzoic acid is slightly soluble in cold water, slightly more soluble in hot water, and also has a certain solubility in ethanol and ether. This solubility property has a great impact on practical applications. For example, in the post-processing stage of chemical synthesis, according to its solubility, suitable solvents can be selected for dissolution, filtration, crystallization and other operations to achieve product purification.
diaminobenzoic acid is relatively stable chemically at room temperature and pressure, but it needs to be protected from light, heat and strong oxidants. Due to light and high temperature or chemical reaction, quality and performance are affected. Strong oxidants will react violently with it or cause danger. When storing and using, appropriate measures should be taken according to their properties, such as placing in a cool and dark place, storing and transporting with oxidants to ensure safe operation and stable material properties.
What are the chemical properties of 3,4-diaminobenzenesulfonic acid
3,4-Dihydroxybenzoic acid is an important organic compound with a variety of unique chemical properties.
It is weakly acidic because of the phenolic hydroxyl group and carboxyl group in the molecule. The oxygen atom in the phenolic hydroxyl group has a lone pair of electrons, which forms a p-π conjugate with the benzene ring, so that the O-H bond electron cloud is biased towards the oxygen atom, and the hydrogen atom is more easily dissociated in the form of protons, showing acidity; the carbonyl group in the carboxyl group has a strong electron-absorbing effect, which enhances the polarity of the oxygen-hydrogen bond in the hydroxyl group, and the hydrogen is also easily ionized, and the acidity is significant.
This compound can undergo esterification reaction. The carboxyl group can be condensed with the alcohol under the catalysis of concentrated sulfuric If it reacts with ethanol, ethyl 3,4-dihydroxybenzoate can be obtained. This reaction is a reversible reaction. Concentrated sulfuric acid acts as a catalyst and water-absorbing agent to push the equilibrium to the right and improve the yield of the ester.
Its phenolic hydroxyl groups are easily oxidized. Because phenolic hydroxyl groups increase the density of electron clouds in the adjacent and para-position of the benzene ring, the benzene ring is more active and vulnerable to attack by oxidants. In case of strong oxidants, such as potassium permanganate, the benzene ring can be oxidized to open the ring; in case of weak oxidants, such as oxygen in the air, the phenolic hydroxyl group can be oxidized to quinones, causing color changes, such as a gradual change from colorless to pink or even darker color.
In addition, the substance can undergo a sub Due to the high density of electron clouds caused by phenol hydroxyl groups, the electrophilic reagents are prone to attack and substitution. If reacted with bromine water, bromine atoms can replace phenyl ring ortho and para-hydrogen atoms to generate brominated products such as 3-bromo-4,5-dihydroxybenzoic acid.
What is the production method of 3,4-diaminobenzenesulfonic acid?
The preparation method of 3,4-dihydroxybenzaldehyde is as follows:
The ancient production method, there are natural extracts. Find all plants, such as the skin and leaves of a certain type of tree, or containing this substance. First take the skin and leaves, soak them in water or other solvents, soak them, filter to remove the residue, and leave the liquid. Then by distillation and other methods, the solvent in the liquid is gradually removed, and the solute is concentrated. After recrystallization, a relatively pure 3,4-dihydroxybenzaldehyde can be obtained. However, this way is subject to raw materials, and the yield is difficult to increase.
Today's production method, mostly chemical synthesis. One method is to use catechol as the starting material, and put it in a reactor with chloroform and sodium hydroxide. The temperature and pressure in the kettle need to be precisely controlled to make the Reimer-Tiemann reaction occur. In this reaction, chloroform is formed in an alkaline environment to form an active intermediate, which interacts with the benzene ring of catechol to introduce an aldehyde group, and then 3,4-dihydroxybenzaldehyde is obtained. After the reaction is completed, the pH of the system is adjusted to neutral by acid, and then the product is separated and purified by extraction, distillation, column chromatography and other steps.
There are also those who use resorcinol as raw material, first through formylation reaction, the protective group of the aldehyde group is introduced. After hydrolysis and other series of reactions, the protective group is removed, and the final product is obtained. This step is slightly more complex, and the yield may be improved, and the raw material resorcinol is easy to obtain, and the cost may be controllable. All kinds of methods have their own advantages and disadvantages, depending on the actual needs, choose the good ones and use them.
What are the precautions for the use of 3,4-diaminobenzenesulfonic acid?
When applying 3% 2C4-hydrobenzarsonic acid, there are several points to pay attention to.
First, this is a highly toxic agent and must be handled with caution. When taking it, it is necessary to wear protective equipment, such as gloves, goggles and masks, to prevent it from touching the skin, entering the eyes or inhaling into the lungs. If you accidentally touch it, rinse it with plenty of water immediately and seek medical attention immediately.
Second, the dose and frequency of administration must be precisely controlled. Excessive use of it will not only fail to replenish the expected effect, but also cause environmental pollution, or cause damage to the application object. It must be administered strictly according to specific needs and instructions.
Third, storage should not be ignored. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources, and must be separated from other chemicals to prevent dangerous interactions. The storage place should also be clearly marked to warn others of its danger.
Fourth, during the application process, pay attention to the surrounding environment. Avoid using it when the wind is strong or precipitation is strong, to prevent it from drifting or losing, causing the scope of pollution to expand. At the same time, pay attention to the impact on surrounding organisms to avoid unnecessary harm to beneficial organisms.
Fifth, after use, properly dispose of the remaining drugs and packaging. Do not dump or discard at will, and dispose of it safely in accordance with relevant regulations to avoid potential threats to the environment.
