1-Ethyl-1H-pyrrole is an organic compound. It has various physical properties, which are described in detail by you today.
Looking at its properties, under room temperature and pressure, 1-ethyl-1H-pyrrole is a colorless to light yellow liquid, like clear water, but it has a unique state. As far as the eye can see, its quality is uniform, without the disturbance of impurities, showing a pure appearance.
As for its smell, it has a special aromatic smell. Although it is not as rich as flowers, it is unique and lingers in the nose, which is impressive. This unique smell is one of its signs. < Br >
When it comes to the boiling point, it is about 159-160 ° C. When the temperature gradually rises, 1-ethyl-1H-pyrrole will be like a feather butterfly, from liquid light to gaseous state, floating in space. The number of this boiling point is one of the keys to its physical properties, and it is related to its state transition under different temperature environments.
Its melting point is about -70 ° C. When the temperature drops to this point, the originally smart liquid will solidify like a slumber and turn into a solid state, and the form will change from flow to fixed, just like time solidifies, and everything is still.
In terms of density, it is about 0.91g/cm ³. It is slightly lighter than water. If it is placed in the same place as water, it can be seen that it floats on the water, just like a light boat floating in blue waves, and it is distinct. This density characteristic also affects its distribution and behavior in various systems.
Solubility is also an important physical property. 1-ethyl-1H-pyrrole is soluble in many organic solvents, such as ethanol, ether, etc., just like a fish entering water, it fuses seamlessly. However, in water, its solubility is limited, only slightly soluble. This property is closely related to its molecular structure, making it exhibit different dissolution behaviors in different solvent environments.
In addition, the physical properties such as vapor pressure and surface tension of 1-ethyl-1H-pyrrole also affect its behavior under specific conditions. However, the two often vary with temperature and other factors, and are also an indispensable part of studying its physical properties. Vapor pressure is related to its volatilization difficulty, and surface tension affects its interaction with other surfaces, both of which affect the physical behavior of 1-ethyl-1H-pyrrole in subtle ways.

The stability of the chemical properties of 1-ethyl-1H-pyrrole is an interesting topic. This compound has a unique structure and has attracted much attention in the field of organic chemistry.
The stability of 1-ethyl-1H-pyrrole depends on the interaction between the atoms in its molecule. The pyrrole ring is a nitrogen-containing five-membered heterocycle and has aromatic properties. This aromaticity imparts a certain stability to the molecule. However, the introduction of ethyl groups on the ring also affects its stability.
From the perspective of electronic effects, ethyl is a donator group. Its donator action can increase the electron cloud density on the pyrrole ring. In some reactions, changes in the density of this electron cloud may affect its reactivity and stability.
Under normal conditions, 1-ethyl-1H-pyrrole is still stable. However, in case of specific chemical reagents or reaction conditions, its stability may be challenged. In case of strong oxidants, the double bonds in the pyrrole ring may be oxidized, resulting in changes in its structure and stability. For example, in a strong acid environment, nitrogen atoms or protons destroy the aromatization of molecules, which in turn affects the stability.
In terms of thermal stability, if the temperature is moderately increased, 1-ethyl-1H-pyrrole may be stable. However, if the temperature is too high, it may cause reactions such as rearrangement and cracking in the molecule, which will damage its stability.
The stability of 1-ethyl-1H-pyrrole is not absolute and will change due to changes in the external chemical environment and physical conditions. In organic synthesis and related studies, this factor must be carefully considered to achieve the expected reaction effect and product stability.

The synthesis method of 1-ethyl-1H-pyrrole has been investigated by chemists throughout the ages. The following are some common methods.
First, pyrrole is used as the starting material and can be obtained by alkylation. Pyrrole has an active nitrogen atom and can undergo nucleophilic substitution with halogenated ethane in the presence of a suitable base. For example, in an alcohol solution of a weak base such as potassium carbonate, the halogen of halogenated ethane is attacked by the pyrrole nitrogen atom, and the halogen leaves to form 1-ethyl-1H-pyrrole. The reaction conditions are relatively mild and the operation is not complicated. However, it is necessary to pay attention to the selection of halogenated ethane and the amount of base. If the activity of halogenated ethane is too high or the amount of base is too high, it is easy to initiate side reactions and cause impure products.
Second, it is converted from derivatives containing nitrogen heterocycles. For example, some pyrrolidine compounds can be converted into 1-ethyl-1H-pyrrole through suitable dehydrogenation reactions. This process often requires specific catalysts, such as transition metal catalysts, to be carried out under high temperature and inert gas protection atmosphere. The key to dehydrogenation is to precisely control the reaction temperature and catalyst activity. If the temperature is too high or the catalyst activity is too strong, or the ring structure is destroyed, which affects the yield of the product.
Third, the pyrrole ring is constructed and ethyl is introduced through a multi-step reaction. First, the prototype of the pyrrole ring is constructed under the condensation reaction with an appropriate carbonyl-containing compound and a nitrogen-containing compound, and then ethyl is gradually introduced and the structure is improved through reduction, alkylation and other steps. Although this approach is a little complicated, the reaction steps and reagents can be flexibly adjusted according to the needs, and the control of the product structure is more accurate. However, the multi-step reaction will inevitably reduce the total yield, and each step requires fine operation and purification to ensure the quality of the product.
These methods for synthesizing 1-ethyl-1H-pyrrole have their own advantages and disadvantages. Chemists should choose their advantages according to actual needs, such as raw material availability, product purity requirements, and cost considerations.

The price range of 1-ethyl-1H-pyrrole in the market is difficult to determine. This is due to the changeable market conditions, supply and demand conditions, differences in quality, and differences in sources, which can cause their prices to vary.
If you study its past, you may know a thing or two. In the past, in some ordinary places, if its quality is acceptable, it is not a very fine product, and its quantity is slightly higher, the price per unit may be between tens of dollars and hundreds of dollars. However, if its quality is good, finely purified, and suitable for high-end fields, such as the research and development of fine chemicals, the preparation of special materials, etc., its price should rise significantly, or it can reach hundreds of dollars per unit. < Br >
And if the quantity is different, the price is also different. Bulk purchase, due to large quantities, the supplier may be given a discount to promote sales, and the price should be lower than the retail purchase. And the origin also has an impact, the origin is close to the place where the raw materials are, or the process is convenient, the cost is reduced, and the price may be slightly lower. However, in different cities, there are differences in north and south, different things in east and west, and the price is difficult to generalize. In short, if you want to know the exact price, you can get the current price when you consult the quotient of chemical materials in real time.
