2,5-Pyridinedicarboxylic acid, 1,6-dihydro-6-oxo-

What are the physical properties of 2% 2C5-diacetic acid, 1% 2C6-diethylamine-6-oxo? Among this substance, 2,5-dimethyl-1,6-diethylamine-6-oxo-related physical properties are as follows:
##1. Appearance and properties
Generally speaking, such organic compounds are mostly colorless to light yellow liquid state at room temperature and pressure. Its color is related to purity. If the impurity content is low, the color is light and nearly colorless and transparent; if it contains a small amount of impurities, it may appear light yellow. This is due to the absorption and scattering characteristics of light by functional groups and chemical bonds in the molecular structure. Under the irradiation of light, the surface of the liquid will have a certain luster, with fluidity, and can flow in the container like a common liquid.
###II. Odor
This substance emits a special irritating amine odor. Diethylamine groups are the main cause of this odor, and amine substances usually have a more pungent odor. This odor is relatively strong and can be perceived by people at a low concentration. Long-term exposure may cause some irritation to the human olfactory system and cause discomfort.
##III. Solubility
From the perspective of dissolution characteristics, it has good solubility in common organic solvents such as ethanol, ether, and acetone. This is because the molecular structure of the substance has similar chemical properties to these organic solvents and follows the principle of "similar miscibility". The molecular polarity of organic solvents such as ethanol, ether, and acetone is similar to the molecular polarity of the substance, and can form a weak intermolecular force with the molecules of the substance, thereby causing the substance to dissolve in it. However, its solubility in water is relatively small. This is due to the large proportion of hydrophobic groups (such as methyl groups, etc.) in its molecules, resulting in weak interactions with water molecules, making it difficult to dissolve in water in large quantities.
###Fourth, boiling point and melting point
Boiling point and melting point are important physical constants of substances. Under normal circumstances, the boiling point of this substance is in a relatively high range, roughly between 180 and 220 degrees Celsius. This is because there are various interaction forces between molecules, such as van der Waals force, hydrogen bonds (if the molecules have the conditions to form hydrogen bonds), etc. These forces make the molecules need to absorb more energy to overcome the mutual binding, from liquid to gaseous, and thus have a higher boiling point. Its melting point is relatively low, about -20 to 0 degrees Celsius, which means that at room temperature, the substance usually exists in liquid form. The low melting point is mainly due to the structural characteristics of the molecule. The arrangement between molecules is not very close and orderly, and the intermolecular forces are relatively weak. Only less energy is absorbed to make the molecule break free from the lattice binding and transform from solid to liquid.

The chemical properties of 2% 2C5-diacetic acid, 1% 2C6-diethylamine-6-oxo-are as follows:
Diacetic acid, acidic, can neutralize with bases, such as reacting with sodium hydroxide to form sodium acetate and water. Because it contains two carboxyl groups, it is more acidic than acetic acid. In the esterification reaction, it can be catalyzed with alcohols in concentrated sulfuric acid and heated to form corresponding esters and water.
1,6-diethylamine, basic, because there are lone pairs of electrons on the nitrogen atom, it can accept protons. Can react with acids to form salts, such as reacting with hydrochloric acid to form hydrochloride salts. Its alkalinity makes it often used as an acid binding agent in organic synthesis, absorbing the acid generated by the reaction and pushing the reaction forward.
6-oxo-this part of the structure, the presence of carbonyl (C = O) makes it have unique chemical properties. Nucleophilic addition reactions can occur, such as reactions with Grignard reagents. Negatively charged hydrocarbons in Grignard reagents attack carbonyl carbons to form new carbon-carbon bonds, which are then hydrolyzed to obtain corresponding alcohols. Reduction reactions can also occur, such as reducing agents such as sodium borohydride, which can be reduced to alcohol hydroxyl groups. < Br >

To obtain 2,5-terephthalic acid and 1,6-adipic acid-6-oxo-generation, the method is as follows:
You can first take an appropriate amount of p-xylene, use cobalt, manganese, etc. as catalysts, and carry out oxidation reactions with air or oxygen at a certain temperature and pressure. In this process, p-xylene is gradually oxidized to form p-methylbenzoic acid, and then further oxidized to terephthalic acid.
As for 1,6-adipic acid-6-oxo-generation, cyclohexanol can be used. Cyclohexanol is oxidized in an acidic environment with strong oxidants such as potassium dichromate or potassium permanganate. Cyclohexanol is first oxidized to cyclohexanone, and then further oxidized to open the ring to form adipic acid. If the reaction conditions are precisely controlled, part of the oxidation product can retain the oxygenated structure at position 6, thereby obtaining 1,6-adipic acid-6-oxy-.
There are also other ways, such as using cyclohexene as a raw material, first oxidizing with ozone, and then treating with an appropriate reducing agent, an intermediate containing aldehyde or carbonyl can be generated, and further oxidation or treatment can also produce the target product. However, regardless of the method, it is necessary to pay attention to the control of the reaction conditions, such as temperature, pH, reaction time, etc., in order to achieve the purpose of higher yield and purity.
