The chemical with CAS 79 - 10 - 7 is acetic acid, a well - known and widely used compound in various industries. As a supplier of CAS: 79 - 10 - 7, I am here to share in - depth knowledge about its solubility characteristics in different solvents, which can help potential customers better understand this product and its applications.
Solubility in Water
Acetic acid is highly miscible with water in all proportions. This is due to its ability to form hydrogen bonds with water molecules. The carboxyl group (-COOH) in acetic acid contains a polar O - H bond and a highly electronegative oxygen atom. Water molecules, which also have polar O - H bonds, can interact with the acetic acid molecules through hydrogen bonding.
When acetic acid is added to water, the hydrogen bonds between water molecules are disrupted, and new hydrogen bonds are formed between acetic acid and water. This process is exothermic, meaning that heat is released during the mixing. The resulting solution is a homogeneous mixture, and the solubility of acetic acid in water is essentially unlimited.
The miscibility of acetic acid in water has significant implications for its applications. In the laboratory, acetic acid - water solutions are commonly used as buffers. For research and analytical purposes, you can consider our Laboratory Grade Acetic Acid For Analytical And Research Use. It is of high purity and suitable for accurate chemical analyses and scientific investigations.
Solubility in Organic Solvents
Ethanol
Acetic acid is also miscible with ethanol. Both acetic acid and ethanol have hydroxyl groups (-OH) that can participate in hydrogen bonding. The non - polar hydrocarbon chains in ethanol and the relatively small non - polar part of the acetic acid molecule also allow for some degree of van der Waals interactions.
The solubility of acetic acid in ethanol makes it useful in the production of esters through esterification reactions. In the presence of an acid catalyst, acetic acid and ethanol react to form ethyl acetate, a common solvent and flavoring agent. This property is exploited in the food, beverage, and perfume industries.
Diethyl Ether
Acetic acid has a moderate solubility in diethyl ether. Diethyl ether is a relatively non - polar solvent, but it has an oxygen atom that can form weak dipole - dipole interactions with the polar groups in acetic acid. The solubility is limited because the non - polar nature of diethyl ether is not fully compatible with the polar carboxyl group of acetic acid.
This solubility characteristic can be used in separation processes. For example, in some extraction procedures, acetic acid can be partitioned between water and diethyl ether based on its different solubilities in these two solvents.
Benzene
Acetic acid has low solubility in benzene, a non - polar aromatic hydrocarbon. Benzene molecules have only weak van der Waals forces, and there are no significant polar groups to interact with the polar carboxyl group of acetic acid. The solubility is mainly due to the small non - polar part of the acetic acid molecule, which can have some weak van der Waals interactions with the benzene molecules.
Solubility in Other Specialized Solvents
DMSO (Dimethyl Sulfoxide)
Acetic acid is soluble in DMSO, a highly polar aprotic solvent. DMSO has a large dipole moment and can solvate both the polar and non - polar parts of the acetic acid molecule. The sulfur - oxygen double bond in DMSO can form strong dipole - dipole interactions with the carboxyl group of acetic acid, while the methyl groups can interact with the non - polar part of the acetic acid.
This solubility is useful in some chemical reactions where DMSO is used as a reaction medium. For example, in certain organic synthesis reactions, DMSO can dissolve both acetic acid and other reactants, facilitating the reaction process.


Acetonitrile
Acetic acid has a good solubility in acetonitrile. Acetonitrile is a polar aprotic solvent with a nitrile group (-C≡N) that can form dipole - dipole interactions with the carboxyl group of acetic acid. The solubility allows for the use of acetic acid - acetonitrile mixtures in various analytical techniques, such as high - performance liquid chromatography (HPLC).
Solubility and Industrial Applications
Agrochemical and Textile Industries
In the agrochemical and textile industries, technical - grade acetic acid is often used. Our Technical Acetic Acid For Agrochemical And Textile Industries is designed to meet the specific requirements of these industries. The solubility of acetic acid in water and organic solvents is crucial in these applications.
In agrochemicals, acetic acid can be used as a solvent or a reactant in the synthesis of pesticides and fertilizers. Its solubility in water allows for easy formulation of aqueous solutions, while its solubility in organic solvents can be exploited in the preparation of emulsifiable concentrates.
In the textile industry, acetic acid is used in dyeing and finishing processes. It can adjust the pH of the dye bath, which affects the dyeing properties of the fibers. The solubility of acetic acid in water and other solvents ensures its uniform distribution in the textile treatment solutions.
Biotech and Pharmaceutical Industries
In the biotech and pharmaceutical industries, biotech - grade acetic acid is required. Our Biotech - Grade Acetic Acid For Cell Culture And Fermentation Systems is of high purity and meets the strict quality standards of these industries.
The solubility of acetic acid in water is essential in cell culture media. It can be used to adjust the pH of the media, which is critical for the growth and survival of cells. Additionally, its solubility in some organic solvents can be useful in the extraction and purification of pharmaceutical compounds.
Conclusion
The solubility characteristics of acetic acid (CAS 79 - 10 - 7) in different solvents are diverse and play a crucial role in its wide range of applications. Whether it is the unlimited solubility in water, the miscibility in ethanol, or the limited solubility in non - polar solvents like benzene, each property has its own significance in various industries.
