What are the physical properties of 3,3,3-trifluoro-2-methyl-2- (trifluoromethyl) propionyl fluoride?
3% 2C3% 2C3-triene-2-methyl-2- (triene-methyl) propionaldehyde, this substance is an organic compound. Its physical properties are as follows:
At room temperature, it may be a colorless to light yellow liquid with a special odor. This odor may be irritating to a certain extent, and the smell can be distinguished.
Its boiling point is within a certain range due to factors such as intermolecular forces. However, the exact value is affected by the interaction of various groups in the molecular structure. Groups such as methyl and trienyl groups may change the intermolecular forces, resulting in different boiling points than simple compounds of the same type.
Melting point is also restricted by molecular structure. The spatial arrangement of molecules and the interaction between groups determine the temperature at which they change from solid to liquid.
In terms of solubility, according to the principle of similarity dissolution, the substance may be slightly soluble in water. Although there are polar aldehyde groups in the molecule, non-polar groups such as trienyl groups and methyl groups account for a large proportion, resulting in weaker forces between them and water molecules. In organic solvents, such as ethanol, ether, etc., it may have better solubility because the intermolecular forces of organic solvents and the compounds are more compatible.
Density may vary compared to water, and the specific value is determined by the relative mass of the molecule and the way of molecular accumulation. The type and quantity of atoms in the molecule determine the relative mass, which in turn affects the density.
Volatility, because it is a liquid and has a certain vapor pressure, it has a certain volatility. The thermal motion of molecules and the intermolecular forces determine their volatilization rate.
The above physical properties are of great significance in the fields of chemical industry and medicine. Knowing its physical properties can be used in synthesis, separation, storage and application to operate reasonably and achieve the desired effect.
What are the chemical properties of 3,3,3-trifluoro-2-methyl-2- (trifluoromethyl) propionyl fluoride
3% 2C3% 2C3-triene-2-methyl-2- (trienomethyl) propionaldehyde, which is an organic compound. Its chemical properties are as follows:
1. ** Reaction of aldehyde group **: Containing aldehyde group, it has typical aldehyde properties. Oxidation reactions can occur, such as with weak oxidant Torun reagent (silver ammonia solution), the aldehyde group is oxidized to carboxyl group, and itself is reduced to precipitate silver, forming a silver mirror, that is, a silver mirror reaction; with Feilin reagent, a brick-red cuprous oxide precipitate is formed. Under the action of strong oxidants such as acidic potassium permanganate, the aldehyde group can be further oxidized to carboxylic acid. At the same time, aldehyde groups can undergo reduction reactions. For example, hydrogen is used as a reducing agent, and under the action of a catalyst, aldehyde groups are reduced to alcohol hydroxyl groups to obtain corresponding alcohols. It can also undergo addition reactions with active hydrogen-containing compounds, such as with alcohols under the action of acidic catalysts to generate semi-acetals, and further react to form acetals.
2. ** Reaction of carbon-carbon double bonds **: The molecule contains carbon-carbon double bonds, which can be added. With the addition of halogen (such as bromine water), bromine atoms are added to the carbon atoms at both ends of the double bond to fade the bromine water; with hydrogen halide, follow the Markov rule, hydrogen atoms are added to the hydrogen-containing more double bond carbon atoms, halogen atoms are added to the hydrogen-containing less double bond carbon atoms; with hydrogen under the action of a catalyst, the double bond becomes a single bond. In addition, carbon-carbon double bonds can undergo oxidation reactions. Under the action of strong oxidants, the double bond breaks, and different oxidation products are generated according to different conditions; polymerization reactions can also occur. Under certain conditions, the double bonds are opened and connected to each other to form a polymer.
3. The reaction of hydrocarbon groups: methyl and triene methyl and other hydrocarbon groups can be substituted under certain conditions, such as under light or high temperature, with halogen elemental radical substitution reaction, halogen atoms replace hydrogen atoms on hydrocarbon groups.
What is the synthesis method of 3,3,3-trifluoro-2-methyl-2- (trifluoromethyl) propionyl fluoride?
To make 3% 2C3% 2C3% 2C3-trifluoro-2-methyl-2- (trifluoromethyl) propionate ethyl ester, you can follow the following ancient method.
First take an appropriate amount of 2-methyl-2 - (trifluoromethyl) propionic acid and place it in a clean reactor. Cool it at low temperature and slowly drop sulfuryl chloride. During this process, the temperature must be strictly controlled to make the reaction proceed smoothly. When the two meet, a substitution reaction occurs. The chlorine atom in the sulfuryl chloride replaces the hydroxyl group of the propionic acid, escaping sulfur dioxide and hydrogen chloride gas. After the reaction is completed, the unreacted sulfuryl chloride and its by-products are removed by reduced pressure distillation to obtain 2-methyl-2- (trifluoromethyl) propionyl chloride.
Take anhydrous ethanol at a time, place it in another reaction vessel, and pre-cool it to a suitable temperature. The 2-methyl-2- (trifluoromethyl) propionyl chloride prepared before is added dropwise to ethanol, and an appropriate amount of acid binding agent, such as pyridine, is added to remove the hydrogen chloride generated by the reaction to promote the right shift of the reaction. The acid chloride is esterified with ethanol, and the reaction gradually becomes complete after several times.
After the reaction is completed, the organic phase is separated by the method of liquid separation. Polyester with dilute hydrochloric acid, sodium bicarbonate solution, and distilled water successively to remove impurities. Then dry the organic phase with anhydrous magnesium sulfate and let it stand for a while to remove the water. Finally, by distillation, collect the fraction with a suitable boiling point to obtain 3% 2C3% 2C3-trifluoro-2-methyl-2 - (trifluoromethyl) ethyl propionate.
The entire synthesis process requires strict compliance with the operating procedures, accurate temperature control, quantity control, and attention to the connection and purification of each step in order to obtain a high-purity target product.
What are the precautions for storing and transporting 3,3,3-trifluoro-2-methyl-2- (trifluoromethyl) propionyl fluoride?
3% 2C3% 2C3-tribromo-2-methyl-2- (tribromo-methyl) butane is an organic compound. When storing and transporting, pay attention to the following things:
First, because of its certain chemical activity, it is recommended to store in a cool, dry and well-ventilated place. Avoid high temperatures, fire sources and strong oxidants to prevent violent chemical reactions, or even the risk of fire or explosion. This can cause its chemical bonds to activate due to high temperatures or oxidants, causing the reaction to go out of control.
Second, this compound has specific requirements for packaging materials. It must be contained in a corrosion-resistant and well-sealed container, preferably glass or specific plastic materials. Because ordinary materials may react with the compound, the packaging will be damaged and the material will leak.
Third, during the handling process, be sure to handle it with care to avoid collisions and falls. Due to its structure or impact, internal chemical bonds are easily broken, causing unstable reactions and increasing safety risks.
Fourth, the storage place should be equipped with complete fire protection and leakage emergency treatment equipment. In the event of a leak, quickly evacuate unrelated personnel and strictly restrict access. Emergency personnel must wear appropriate protective equipment and do not allow the leak to come into contact with combustible substances. Small leaks can be absorbed by inert materials such as sand and vermiculite; large leaks need to be dammed and contained before treatment.
Fifth, the temperature and humidity of the storage environment should also be closely monitored and regulated. Too high humidity or reactions such as compound hydrolysis, excessive temperature fluctuations also affect its stability. Therefore, it is appropriate to set up a temperature and humidity monitoring device to maintain a suitable range according to its characteristics.
