CAS 68937 - 41 - 7 is a chemical compound that has been a subject of interest in various industrial applications, particularly in the field of flame retardants. As a supplier of CAS 68937 - 41 - 7, I often receive inquiries about its phase transition temperatures. Understanding these temperatures is crucial for its proper handling, storage, and application in different processes.
What is CAS 68937 - 41 - 7?
CAS 68937 - 41 - 7 is commonly associated with certain types of flame retardant formulations. Flame retardants are substances added to materials to reduce their flammability and slow down the spread of fire. This specific compound has unique chemical properties that make it effective in enhancing the fire - safety characteristics of a wide range of products, including plastics, textiles, and foams.
Phase Transitions: An Overview
Phase transitions are physical changes that occur when a substance changes from one state of matter to another. The most common phase transitions are melting (from solid to liquid), freezing (from liquid to solid), vaporization (from liquid to gas), and condensation (from gas to liquid). Each phase transition occurs at a specific temperature, which is determined by the intermolecular forces and the chemical structure of the substance.
Phase Transition Temperatures of CAS 68937 - 41 - 7
The phase transition temperatures of CAS 68937 - 41 - 7 can vary depending on its purity, the presence of impurities, and the specific formulation. Generally, the melting point of CAS 68937 - 41 - 7 is relatively low compared to some other flame retardants. This low melting point makes it suitable for applications where it needs to be incorporated into materials during the manufacturing process at relatively low temperatures.
The melting point of a high - purity sample of CAS 68937 - 41 - 7 typically ranges from - 20°C to 10°C. This means that at temperatures below - 20°C, the compound exists in a solid state, while above 10°C, it is in a liquid state. The exact melting point can be determined through differential scanning calorimetry (DSC), a technique that measures the heat flow associated with phase transitions.
The boiling point of CAS 68937 - 41 - 7 is much higher, usually above 200°C. At temperatures between the melting point and the boiling point, the compound is in a liquid state. This liquid state allows it to be easily mixed with other materials, such as polymers, to form homogeneous flame - retardant composites.
Importance of Knowing Phase Transition Temperatures
Knowing the phase transition temperatures of CAS 68937 - 41 - 7 is essential for several reasons. In the manufacturing process, understanding the melting point helps in determining the appropriate processing temperature. If the temperature is too low, the compound may not melt completely, leading to poor dispersion in the matrix material. On the other hand, if the temperature is too high, it may cause thermal degradation of the compound, reducing its flame - retardant effectiveness.
During storage, the phase transition temperatures also play a crucial role. The compound should be stored at a temperature below its melting point to maintain its solid state and prevent any potential leakage or degradation. Additionally, if the compound is stored at a temperature close to its boiling point, there is a risk of vaporization, which can lead to loss of the compound and potential safety hazards.
Applications of CAS 68937 - 41 - 7 Based on Phase Transitions
In the plastics industry, the low melting point of CAS 68937 - 41 - 7 allows it to be easily incorporated into plastic resins during the extrusion or injection - molding process. The liquid state of the compound at relatively low temperatures ensures good dispersion and compatibility with the plastic matrix, resulting in improved flame - retardant properties of the final product.
In the textile industry, CAS 68937 - 41 - 7 can be applied as a flame - retardant finish. The liquid state of the compound at room temperature makes it suitable for padding or spraying onto textile fabrics. After application, the compound can be fixed onto the fabric fibers, providing long - lasting flame - retardant protection.
Comparison with Other Flame Retardants
When compared to other flame retardants such as Tri(1,3 - dichloropropyl)phosphate, Tris(chloropropyl) Phosphate TCPP - LO, and Tetraphenyl Resorcinol Bis(diphenylphosphate), CAS 68937 - 41 - 7 has a relatively low melting point. This property gives it an advantage in applications where low - temperature processing is required.
For example, some high - temperature flame retardants may require processing temperatures above 200°C, which can limit their use in heat - sensitive materials. In contrast, the low melting point of CAS 68937 - 41 - 7 makes it suitable for a wider range of materials and manufacturing processes.
