2-% -5-ethylaminoethyl ether, this physical property is special. Under normal conditions, it is mostly a transparent liquid, like clear water, uniform to the ground and good flow, swaying like a smooth flow.
Smell it, its taste is special, slightly irritating, but not a strong pungent smell. Under the smell, there is a special smell of ether, as if there is a mysterious hidden in the dark.
Its boiling quality is good, roughly to a certain extent. When the temperature of the liquid rises to the boiling temperature, the liquid will be like the essence of being awakened, and it will begin to boil and turn, and will be transformed from the liquid, rising in the air. And its melting time also has a specific value. In low-temperature environments, if it is melted, it will be melted from solid to liquid, like ice and snow.
Furthermore, its solubility is also worthy of investigation. In a wide range of solvents, it exhibits good solubility, and can be miscible with solutions such as ethanol and ether, just like water emulsifying, forming a uniform mixture. However, the solubility in water is limited, dripping into water, such as oil droplets into water, slightly dispersed, completely melted, floating on the water surface or slightly reduced.
Its density is also fixed, relative to water, or heavy or heavy, in a specific ratio. On the stage of chemical reaction, due to its special molecule, that is, the combination of ethyl aminoethyl ether containing ethyl, it has a certain anti-activity, which can be used for many synthetic reactions, such as etherification, substitution, etc., It plays an indispensable role in the field of chemical reaction.

The chemical properties of 2-% -5-ethylaminoethylaminopyridine are also determined. In this compound, the aminopyridine atom is characterized by its properties, and the reaction of the aminopyridine is reversed. However, in this compound, the interaction of other groups makes the activity of the whole aminopyridine appear specific.
5-ethylaminoethylaminopyridine part, the introduction of the ethyl group makes the molecule have a certain lipid solubility, and the presence of the amino group gives the molecular properties. The solitary child on the nitrogen atom in the amino group can be influenced by the interaction of the aminopyridine or other molecules, so the interaction of the aminopyridine and the co-effect of the aminopyridine. Pyridine itself is aromatic, and the distribution of its pi-molecules affects the density of the sub-cloud of the amino group.
In this way, 2-%-5-ethylaminoethylaminopyridine is determined by the interaction of each group. The distribution of the sub-cloud of molecular integration is determined, so the chemical properties are not determined. Under normal circumstances, unless it encounters oxidation, original or special catalytic components, this compound rarely undergoes self-reaction. Its characterization makes it suitable for phase determination or as a raw material for chemical researchers.

To prepare 2-cyanogen-5-methylhydroxybenzyl ketone, there are various methods.
First, the corresponding halogenate can be started. First, take a suitable halogenated aromatic hydrocarbon and let it interact with the cyanide reagent to introduce a cyanide group. The cyanidation process requires the selection of an appropriate solvent and catalyst to make the reaction smooth and efficient. For example, taking a halogenated toluene as an example, in a suitable organic solvent, add a catalyst such as cuprous cyanide and stir at controlled temperature to obtain a cyanide-containing intermediate. Then, the intermediate is subjected to a hydroxylation step. Hydroxyl groups can be introduced by reaction paths such as nucleophilic substitution. If water or alcohol reagents under basic conditions are reacted with intermediates, the hydroxyl group can replace the corresponding group to obtain a product containing cyanide and hydroxyl groups. Finally, through carbonylation, a carbonyl group is introduced to achieve the synthesis of 2-cyano- 5-methylhydroxybenzyl ketone. The carbonylation method can choose carbon monoxide and a suitable metal catalyst system to react at a specific pressure and temperature to successfully integrate carbonyl groups into the molecular structure.
Second, the compound containing carbonyl can be started. First, a carbonyl-containing aromatic hydrocarbon derivative is modified with its methyl group. A methyl group can be introduced through an alkylation reaction, and a suitable methylation reagent, such as iodomethane, can be selected. Under the catalysis of a base, the methyl group can be successfully connected to the molecule. Subsequently, the carbonyl group in the molecule is converted to generate a hydroxyl group. This step can be reduced by a reduction reaction, such as reducing the carbonyl group to a hydroxyl group with an isothermal reducing agent of sodium borohydride. After that, the cyanidation step is carried out, and the cyanide reagent, such as potassium cyanide, is reacted in a suitable solvent in the presence of a phase transfer catalyst to obtain the final target product 2-cyano- 5-methylhydroxybenzyl ketone.
Third, a multi-step condensation reaction can also be considered. Select appropriate small molecule compounds, such as aldodes, ketones, etc., and gradually build a molecular skeleton through condensation reaction. For example, first, one molecule of methyl-containing aldehyde and another molecule of cyanogen-containing aldehyde are condensed with hydroxyaldehyde under the action of a basic catalyst to form an intermediate containing double bonds. Then the intermediate is hydrogenated and reduced to saturate the double bonds. At the same time, the aldehyde groups in it are properly converted to introduce hydroxyl groups and carbonyl groups. After multiple steps of delicate reaction regulation, 2-cyano- 5-methylhydroxybenzyl ketone is finally synthesized. This synthesis path requires precise control of the reaction conditions at each step to ensure the selectivity and yield of the reaction.

2-%-5-ethylcarbamoethylpyridine, which is a very important chemical, its market is determined, and its price is determined by many factors.
First, the quality of the raw material is very deep. If the product is formed, there are raw materials such as raw materials, and the cost of 2-%-5-ethylcarbamoethylpyridine will be affected. If the cost of the product is increased, or the required materials for synthesis are raised due to supply obstruction, it can cause its price to rise.
Second, the ease of synthesis is also due to the degree of ease. If the synthesis of this compound requires complex steps and harsh inverse components, such as high cost, high cost, special catalysis, etc., the cost of production will be high, and the market will also be high.
Third, the supply and demand of the market is about low. If the market demand for 2-%-5-ethylcarbamoethylpyridine is strong, and the supply is limited, such as due to the limitation of production technology or the lack of commercial production, its price will rise; conversely, if the demand is tired, the supply is not in demand, and the price is easy to slip.
Fourth, the production cost of the raw mold is also low. The production cost of the large mold is low, and the cost of the production may be reduced due to the low molding efficiency, and the cost may be more reasonable; the production cost of the small mold is thin, and the cost of the grid is higher.
Because of this, it is not easy to determine the price of 2-%-5-ethylcarbamoethylpyridine. Its price or due to the above-mentioned factors, there will be a large wave in the market, or 10 to 100 yuan per gram, or even more, depending on the situation of the market.
