What are the physical properties of 1,1,2,2,3,3,4,4,4-nonafluoro-1-butane sulfonic acid?
1-Butyne-1-heptanoic acid is an organic compound with unique physical properties and is widely used in chemical, pharmaceutical and other fields. Its physical properties are as follows:
1. ** Appearance and properties **: At room temperature and pressure, this compound may be a colorless to light yellow liquid. Due to the molecular structure containing a variety of functional groups, it presents a specific physical appearance. In industrial production and experimental operations, its purity and state can be preliminarily judged.
2. ** Melting boiling point **: Melting point is about -40 ° C, boiling point is about 240-245 ° C. The melting boiling point is affected by the intermolecular force and structure. It contains alkynyl groups, aldehyde groups, and carboxyl groups. The intermolecular interaction is complex, and the boiling point is relatively high, so that the compound exists stably in a liquid state at room temperature and pressure. This property is of great significance for its separation, purification and storage. For example, when separating the compound by distillation, the temperature needs to be precisely controlled according to the boiling point.
3. ** Solubility **: Slightly soluble in water, soluble in organic solvents such as ethanol, ether, and chloroform. Because the molecule has a certain polarity, the alkynyl group is non-polar with the longer carbon chain part, and the aldehyde group and carboxyl group are polar, resulting in limited solubility in water, but it can be well miscible with organic solvents. This property is used in organic synthesis and drug development to select suitable solvents to promote reaction progress or separate products.
4. ** Density **: The density is about 1.05 - 1.10 g/cm ³, which is slightly larger than water. Density, as a physical constant, is crucial in chemical production when it involves material measurement, mixing ratio control and other operations. The amount of material can be determined by density measurement to ensure that the reaction is carried out in a predetermined proportion.
5. ** Volatility **: Volatility is relatively low. Due to its strong intermolecular force, molecules need high energy to escape from the liquid phase to the gas phase. This property affects its stability during storage and use. No special anti-volatilization measures are required during storage. During use, there is less volatilization loss and little impact on the environment and the health of operators.
What are the chemical properties of 1,1,2,2,3,3,4,4,4-nonafluoro-1-butane sulfonic acid
1-Nonanol succinic acid is an organic compound with the following chemical properties:
1. ** Acidic **: This compound contains a carboxyl group (-COOH), so it is acidic. In water, the carboxyl group can partially ionize hydrogen ions (H 🥰), making the solution acidic. It can neutralize with bases, such as with sodium hydroxide (NaOH), to generate corresponding carboxylic salts and water. The reaction equation is: R - COOH + NaOH → R - COONa + H2O O (R represents the rest of 1-nonanol succinic acid except carboxyl groups).
2. ** Esterification reaction **: The compound contains both carboxyl groups and hydroxyl groups (if the hydroxyl group of the 1-nonanol part is retained), and an esterification reaction can occur. When co-heated with alcohols under acid catalysis, the carboxyl group dehydrates and condensates with the alcohol hydroxyl group to form an ester. If reacted with ethanol, an ester and water are formed. The reaction formula is: R - COOH + C < H > OH > R - COOC < H > + H < O (the reaction requires concentrated sulfuric acid as a catalyst and heating, which is a reversible reaction). Similarly, its hydroxyl groups may also be esterified with other carboxylic acids.
3. ** Nucleophilic Substitution Reaction **: Nucleophilic substitution reactions can occur in some parts of the molecule. If the carbonyl group (C = O) in the carboxyl group has a certain electrophilicity, the nucleophilic reagent can attack the carbonyl carbon and initiate a substitution reaction. If a suitable nucleophilic reagent is available, the hydroxyl group on the carboxyl group can be replaced to form a new compound.
4. ** Redox Reaction **: From a structural point of view, the hydroxyl group can be oxidized. Under the action of a suitable oxidant, such as when heated and in the presence of a specific catalyst, it can be gradually oxidized to an aldehyde group (-CHO), or even further oxidized to a carboxyl group (if there is only one carboxyl group in the original, a diacid may be formed after oxidation, etc.). Conversely, if a suitable reducing agent is present, some unsaturated bonds or reducible groups
What are the synthesis methods of 1,1,2,2,3,3,4,4,4-nonafluoro-1-butane sulfonic acid?
To obtain 1-nonene-1-alkyd, the following synthesis methods can be used:
First, it can be obtained by a specific reduction reaction of 1, 1, 2, 2, 3, 3, 4, 4-nonafluoro-nonanoic acid. Select a suitable reducing agent, such as lithium aluminum hydride, and under suitable reaction conditions, reduce the carboxyl group to an alcoholic hydroxyl group to obtain the target product. This process requires attention to the temperature of the reaction, the choice of solvent, and the amount of reducing agent to avoid excessive reduction or other side reactions. For example, in an anhydrous ether solvent, slowly add lithium aluminum hydride dropwise at low temperature, and then hydrolyze to obtain the product.
Second, fluorine-containing halogenated hydrocarbons and corresponding carboxylic acid derivatives are used as starting materials. First, a fluorohalogenated hydrocarbon is reacted with metal magnesium to form a Grignard reagent, such as 1, 1, 2, 2, 3, 4, 4-nonafluoro-halonononane and magnesium in anhydrous ether to obtain a Grignard reagent. Then the Grignard reagent is reacted with a carbonyl compound, such as acetoxylate, and after hydrolysis, 1-nonene-1-alkyd can be obtained. The key to this process is that the preparation of Grignard reagents requires an anhydrous and oxygen-free environment, and the proportion of the reaction material needs to be precisely controlled.
Third, through the addition reaction of olefins. First select a suitable fluoroolefin and add it to a reagent containing carboxyl groups and functional groups that can be converted into alcohol hydroxyl groups. For example, 1,1,2,3,3,4,4,4-nonene and a specific carboxylation reagent are added under the action of a catalyst, and then the subsequent functional group conversion converts the convertible group into an alcohol hydroxyl group to obtain the target product. The selection of catalysts and the optimization of reaction conditions are very important to ensure the selectivity and yield of the addition reaction.
