What are the physical properties of 2,3-difluorotrifluorotoluene?
2% 2C3 -diethyltriethyl ether, its physical properties are worth investigating. Under normal temperature, this substance is mostly in a liquid state, with a clear and transparent texture, like a clear spring, and excellent visibility. Its smell is slightly specific, not pungent and intolerable, but also has its own unique fragrance, lingering in the nose.
As for its density, it is lighter than water. If placed in water, it will float on the water surface, like a light boat floating on a blue wave. Its boiling point is also fixed. Due to the force between molecules, at a specific temperature, it can be converted from liquid to gas, turning into light smoke and rising away.
In terms of solubility, it is quite compatible with organic solvents, such as ethanol and ether, just like fish get water, blending with each other without any difference. However, in water, its solubility is relatively limited, and it is difficult for the two to be completely miscible, which is still clear.
Its volatility is also an important physical property. Under appropriate environmental conditions, it can evaporate slowly, and its molecules break free and escape into the air, like an invisible spirit, quietly disappearing into the invisible. This property needs to be carefully considered when storing and using, to prevent it from evaporating too quickly and causing loss.
Furthermore, its viscosity is moderate, neither thick like oil, sluggish flow, nor too thin like water, without resistance. When flowing, it exhibits just the right degree of fluidity, which is also of unique significance in industrial applications and experimental operations.
What are the synthesis methods of 2,3-difluorotrifluorotoluene?
There are several methods for the synthesis of 2% 2C3-diethyltriethylmethyl ether.
First, the method of reacting alcohol with halogenated hydrocarbons. Select an appropriate alcohol, such as ethanol, and halogenated hydrocarbons. If diethyltriethylhalomethane, in an alkaline environment, use a base such as potassium carbonate as an acid binding agent, in an appropriate solvent, such as acetone, heat and stir. The halogen atoms of halogenated hydrocarbons are quite active, and the hydroxyl oxides of alcohols are nucleophilic. Both can undergo nucleophilic substitution reactions. Through this process, the hydrogen of the hydroxyl group is combined with the halogen atom to form hydrogen halide, which is captured by the base, and the rest of the alcohol is connected to the hydrocarbon group of the halogenated hydrocarbons, and finally forms 2% 2C3-diethyltrieth
Second, use the Williamson synthesis method. This is a commonly used method for synthesizing ethers. First, the alcohol is made into sodium alcohol. Take ethanol as an example, add sodium metal, and the sodium reacts with ethanol to generate sodium ethanol and hydrogen. After that, the sodium ethanol is reacted with diethyltriethylhalide methane. The ethoxy negative ion of sodium ethanol is a strong nucleophilic reagent, which can attack the carbon atoms of the halogenated methane, and the halogen atoms leave to form 2% 2C3 -diethyltriethyl ether. This reaction needs to be controlled by the reaction conditions, and the temperature should not be too high to avoid elimination.
Third, it is prepared by the condensation reaction of aldehyde or ketone with alcohol. If diethyltriacetaldehyde and ethanol are taken as an example, under acid catalysis, the carbonyl group of aldehyde and the hydroxyl group of ethanol undergo nucleophilic addition first to form hemiacetal intermediates. The hydroxyl group of hemiacetal is then dehydrated with the hydroxyl group of another molecule of ethanol under acid catalysis to form acetal, that is, 2% 2C3 -diethyltriethyl ether. The acid catalyst can generally be selected from p-toluenesulfonic acid, etc. During the reaction, the generated water can be removed by azeotropic means, so that the reaction equilibrium moves in the direction of ether formation.
The above synthesis methods have their own advantages and disadvantages, and the appropriate method should be selected according to the actual situation, such as the availability of raw materials, cost, product purity requirements, etc.
