CAS 56 - 75 - 7 refers to DDT (dichlorodiphenyltrichloroethane), a well - known synthetic organic insecticide. In this blog, we'll delve into the solubility of DDT in water, and as a supplier of CAS 56 - 75 - 7, we'll also touch on some related aspects.
Solubility of DDT in Water
DDT is a highly non - polar compound. Its chemical structure consists of multiple benzene rings and chlorine atoms, which endow it with a significant degree of hydrophobicity. The solubility of DDT in water is extremely low. At room temperature (around 25°C), the solubility of DDT in water is approximately 1.2 - 2 μg/L.
This low solubility can be explained by the principles of chemistry. Water is a polar solvent, with a bent molecular structure and a large electronegativity difference between oxygen and hydrogen atoms, resulting in a dipole moment. On the other hand, DDT has a relatively symmetric and non - polar structure. According to the "like dissolves like" rule, non - polar substances tend to dissolve better in non - polar solvents, while polar solvents like water have limited ability to dissolve non - polar compounds such as DDT.
The low solubility of DDT in water has several important implications. Firstly, in the environment, when DDT is released into water bodies, it doesn't readily dissolve and instead tends to adsorb onto suspended particles or sediment. This can lead to its accumulation in aquatic sediments over time. Secondly, from a biological perspective, the low water solubility makes it difficult for DDT to be directly taken up by aquatic organisms through simple diffusion in water. However, DDT can still enter the food chain as it bioaccumulates in fatty tissues of organisms.
Factors Affecting DDT Solubility in Water
Although the solubility of DDT in water is generally low, several factors can influence this solubility to some extent.
Temperature
An increase in temperature usually leads to an increase in the solubility of most substances, and DDT is no exception. As the temperature rises, the kinetic energy of water molecules and DDT molecules increases. This enhanced molecular motion allows for more effective interaction between water and DDT molecules, facilitating the dissolution process. However, even with a significant increase in temperature, the solubility of DDT in water remains relatively low compared to more water - soluble compounds.
pH
The pH of the water can also have an impact on DDT solubility. DDT is a relatively stable compound under normal pH conditions in natural water bodies (pH range of 6 - 8). However, in extremely acidic or alkaline conditions, some chemical reactions might occur that could potentially affect its solubility. For example, in highly alkaline solutions, there could be a slow hydrolysis of DDT, which might change its chemical structure and solubility characteristics.
Presence of Surfactants
Surfactants are compounds that can reduce the surface tension of water. When surfactants are present in water, they can form micelles. These micelles have a hydrophobic core and a hydrophilic outer layer. DDT molecules can be incorporated into the hydrophobic core of the micelles, effectively increasing its apparent solubility in water. This phenomenon is often exploited in some remediation processes where surfactants are used to enhance the removal of DDT from contaminated soil or water.

We also have 2,2'-Bis(2 - chlorophenyl)-4,4',5,5'-tetraphenyl - 1,2'-biimidazole CAS#7189 - 82 - 4, which is an important intermediate in the synthesis of various organic compounds.
Applications of DDT
Although DDT use has been restricted in many countries due to its environmental persistence and bioaccumulation potential, it still has some limited applications in certain regions.
In the past, DDT was widely used in agriculture to control a variety of insect pests, such as mosquitoes, flies, and agricultural pests. Its effectiveness in reducing the spread of diseases like malaria was remarkable. In some developing countries where malaria is still a major health problem, DDT is still used in indoor residual spraying programs under strict guidelines from the World Health Organization (WHO). This method involves spraying DDT on the interior walls of houses, which can kill mosquitoes that land on the walls, thus reducing the transmission of malaria.
Conclusion
The solubility of DDT (CAS 56 - 75 - 7) in water is extremely low, which is mainly due to its non - polar chemical structure and the "like dissolves like" principle. Temperature, pH, and the presence of surfactants can affect its solubility to some extent. As a supplier of CAS 56 - 75 - 7, we are committed to providing high - quality products and excellent technical support.
