As a result, diethyl, with its special chemical properties, plays an important role in the fields of food, chemical products, and synthetic engineering, etc., and has an important role in the development of each industry and the wealth of people's lives.
What are the physical properties of diethylamine?
Diethylamine has all kinds of physical properties. It is a colorless liquid with a pungent smell of ammonia. The boiling point is about 55.5 ° C. Under normal temperature and pressure, it is more volatile and shows a flowing state.
Its density is less than that of water, about 0.706g/cm ³, so if diethylamine is mixed with water, it can float on the water surface. And slightly soluble in water, it can be miscible with organic solvents such as ethanol and ether, which is similar to the principle of miscibility. Organic solvents such as ethanol and ether have similar molecular structures to diethylamine, so they can miscible with each other.
The vapor of diethylamine is heavier than air, and its relative density is about 2.54 (air = 1). Because of its heavy steam, when it leaks, the steam is easy to spread close to the ground, and it is easy to burn and explode in case of open flames and hot topics. This is its danger.
Diethylamine is alkaline and can neutralize with acids to generate corresponding salts. Although its alkalinity is weaker than that of strong bases such as sodium hydroxide, it is often used as a base reagent in organic chemistry, which can participate in many organic synthesis reactions, adjust the pH of the reaction system, and promote the smooth progress of the reaction.
Looking at its physical properties, it is useful in many fields such as chemical industry and pharmacy. Due to its volatility and solubility, it can be used as a solvent in some organic synthesis reactions to promote the mixing and dispersion of reactive substances. Due to its alkalinity, it can capture protons in specific reactions and promote the reaction in the desired direction. It is a chemical with a wide range of uses.
What are the chemical properties of diethylamine?
Diethylamine is an organic compound with rich and diverse chemical properties. Here is an ancient saying:
Diethylamine is alkaline. In water, it can be combined with protons, such as the "Book of Rites · The Mean" cloud "to neutralize, heaven is the status of all things, education", which can be combined with hydrogen ions ionized by water to form diethylamine cations. This reaction is like the combination of yin and yang, so that the system reaches a new balance. Because of its alkalinity, it can neutralize with acids, just like softness, acid and base blend. When exposed to hydrochloric acid, the two react rapidly to form diethylamine hydrochloride. This process is like water emulsion blending, and the properties of the products are different from those of the previous two. This is the wonder of chemical changes.
Furthermore, the nitrogen atom of diethylamine contains lone pairs of electrons and is nucleophilic. In many chemical reactions, it is like a warrior taking the initiative to attack, and its lone pairs of electrons can attack atoms or groups that lack electrons. In the nucleophilic substitution reaction, diethylamine can attack the check point of the halogen atom of halogenated hydrocarbons, and the halogen atom leaves, resulting in the formation of new organic compounds. This change is like a shift in the universe, creating a different substance.
In addition, diethylamine can participate in the acylation reaction. When it encounters with an acid chloride or an acid anhydride, it is like like like like-minded people polymerizing, and acylation occurs. The hydrogen on the nitrogen atom is replaced by an acyl group to form an amide compound. This process is like a phoenix nirvana. Diethylamine has undergone changes, and the amides generated have unique uses in many fields.
Diethylamine is volatile and flammable in the air. In case of open flame or hot topic, it is like dry wood encountering fire, which can cause combustion and explosion. This characteristic needs to be treated with caution. When operating, it should be like walking on thin ice and strictly observing safety regulations. Its chemical properties are diverse and it plays a significant role in organic synthesis and other fields. However, due to its characteristics, it is necessary to pay great attention when using it.
What are the safety precautions for diethylamine during use?
Diethylamine is a highly volatile and corrosive chemical. When used, all kinds of safety matters must be observed.
First, it is related to ventilation. Where diethylamine is used, good ventilation equipment must be installed to keep the indoor air fresh. If it is used in a closed and poorly ventilated place, the volatile gas of diethylamine accumulates. First, it is easy to cause the user to inhale too much, damage the respiratory tract, and in light cases cough, sore throat, and in severe cases cause respiratory inflammation, pulmonary edema and other diseases. Second, the gas concentration reaches a certain level, and in case of open flames and hot topics, there is a risk of explosion. Therefore, it is advisable to have a mechanical ventilation device at the work place. If it is a laboratory, a fume hood is also necessary to ensure its normal operation.
Second, the use of protective equipment. Users in front of protective clothing, choose chemical-resistant materials, such as protective clothing made of neoprene rubber and nitrile rubber, which can effectively prevent diethylamine from contacting the skin. At the same time, protective gloves must be worn. The material of gloves must also be resistant to diethylamine corrosion. During operation, beware of skin exposure caused by damage to the gloves. Facial protection is also essential. Wear chemical safety protective glasses and, if necessary, a mask to prevent diethylamine liquid from splashing into the eyes. Because it is highly irritating to the eyes, it can cause eye burns. Respiratory protection is also critical. In general operation, a filter gas mask can be worn; if in a high-concentration environment or in an emergency, a self-contained respirator is required.
Third, operating specifications. When taking diethylamine, the action should be slow to avoid it splashing. When pouring liquid, the container mouth is tightly docked and operated in a ventilated place. If dilution is required, diethylamine should be slowly injected into the water and stirred constantly. Do not do the opposite to prevent violent reactions. During operation, fireworks are strictly prohibited, away from heat sources and fires, and the electrical equipment used should also be explosion-proof.
Fourth, storage is essential. Diethylamine should be stored in a cool and ventilated warehouse, away from fire and heat sources, and the storage temperature should not exceed 30 ° C. It should be stored separately from oxidants, acids, etc., and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials, just in case.
Fifth, emergency treatment. If you accidentally come into contact with diethylamine on the skin, you should immediately remove the contaminated clothing, rinse with a large amount of flowing water for at least 15 minutes, and then seek medical attention. If it splashes into the eyes, immediately lift the eyelids, rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes, and seek medical attention immediately. If inhalation, quickly leave the scene to fresh air, keep the respiratory tract unobstructed, such as breathing difficulties, give oxygen, when breathing and heartbeat stop, immediately carry out cardiopulmonary resuscitation and seek medical attention.
What are the preparation methods of diethylamine?
The methods of diacetyl are as follows:
First, it can be obtained from acetic anhydride and acetic acid under the action of appropriate catalysis. The method is to take a number of acetic anhydride, and the amount of acetic acid is co-placed in the reactor, and a carefully taken catalyst is added. The catalyst needs to be able to effectively promote the reaction between the two, and the reaction should not be introduced. In general, it is necessary to keep the reaction at a certain degree to make the reaction smooth. During this period, the reaction process is close. When the reaction reaches the stage of the reaction, a mixture containing diacetyl is obtained, and then a series of means of extraction, such as steaming, extraction, etc., can be obtained. Diacetyl.
Second, vinyl ketone and acetic acid can also be reacted with diacetyl. First, vinyl ketone is passed into the reactor containing acetic acid, and this process is controlled to control the rate of entry, so as to ensure that the two are fully and appropriately connected. The reaction parts are also very important, and the degree and performance need to be precisely controlled. After the reaction is completed, the obtained product needs to be refined in the same step, remove the raw materials, side substances, etc. that have not been reacted, and then obtain diacetyl.
Third, through some specific synthetic pathways, the starting materials of the compound are used to gradually build diacetyl molecules in multiple steps. This approach is often more difficult, and requires a deep understanding of the theory of the reaction. First of all, carefully reverse the way, according to the properties of the starting material, and the exact reverse of the reverse parts, in turn, each step needs to be controlled by grid, to ensure the reverse rate and the degree of material. After all the reverse steps are completed, a comprehensive review is made to ensure the high degree of diacetyl.
