What are the physical properties of 50% Cyanamide?

As a supplier of 50% Cyanamide, I am often asked about its physical properties. In this blog post, I will delve into the various physical characteristics of 50% Cyanamide, providing you with a comprehensive understanding of this important chemical compound.

Appearance and State

50% Cyanamide is typically a clear, colorless to slightly yellowish liquid. The slight yellowish tint can sometimes develop over time due to oxidation or the presence of trace impurities. The liquid form makes it relatively easy to handle and transport compared to some solid chemicals. It has a smooth consistency, similar to many other aqueous solutions, which allows for efficient mixing and application in various industrial processes.

Density

The density of 50% Cyanamide is an important physical property as it affects its handling and storage. Generally, the density of a 50% Cyanamide solution is around 1.08 - 1.10 g/cm³ at 20°C. This density is slightly higher than that of water, which has a density of 1 g/cm³ at the same temperature. The relatively higher density means that 50% Cyanamide will sink in water if the two are mixed without proper agitation. This property is crucial in industrial settings where accurate measurement and handling of the chemical are required. For example, when storing 50% Cyanamide in tanks, the density information helps in calculating the volume - mass relationship, ensuring that the tanks are not overfilled and that the correct amount of the chemical is used in production processes.

Solubility

50% Cyanamide is highly soluble in water. This high solubility is one of the reasons why it is commonly used in aqueous - based industrial applications. When added to water, it dissolves readily, forming a homogeneous solution. This solubility also allows for easy dilution to achieve different concentrations as per the requirements of specific processes. Additionally, 50% Cyanamide is soluble in some organic solvents such as ethanol and methanol. This solubility in organic solvents broadens its range of applications, especially in industries where organic - based reactions or formulations are involved. For instance, in the synthesis of certain pharmaceuticals or agrochemicals, the ability to dissolve in organic solvents enables 50% Cyanamide to participate in reactions within organic reaction media.

Boiling and Melting Points

The boiling point of 50% Cyanamide is influenced by the water content in the solution. Since it is a 50% solution, the boiling point is closer to that of water than pure Cyanamide. The presence of Cyanamide in the solution elevates the boiling point slightly compared to pure water. At standard atmospheric pressure, the boiling point of 50% Cyanamide is around 102 - 105°C. The melting point of 50% Cyanamide is also affected by the water content. It usually freezes at a temperature below 0°C, typically around - 10 to - 15°C. These boiling and melting points are important considerations for storage and transportation. In cold climates, proper insulation or heating may be required to prevent the solution from freezing, while in high - temperature environments, appropriate cooling measures need to be in place to avoid excessive evaporation.

Viscosity

The viscosity of 50% Cyanamide is relatively low. This low viscosity allows for easy pumping and flow through pipes and processing equipment. It can be easily transferred from storage tanks to reaction vessels or other parts of the production line. The low viscosity also facilitates efficient mixing with other chemicals, ensuring uniform distribution and reaction. In processes where rapid and efficient mixing is essential, such as in the production of fertilizers or pesticides, the low viscosity of 50% Cyanamide is a significant advantage.

Odor

50% Cyanamide has a characteristic odor that is often described as pungent and slightly ammoniacal. The odor can be detected even at relatively low concentrations. This odor serves as a warning sign in case of leaks or spills. However, prolonged exposure to the odor can be irritating to the respiratory system, eyes, and skin. Therefore, proper ventilation is necessary when working with 50% Cyanamide to minimize the risk of inhalation and exposure.

Applications Based on Physical Properties

The physical properties of 50% Cyanamide make it suitable for a wide range of applications. In the agricultural industry, its high solubility in water allows for easy formulation into fertilizers. The low viscosity enables efficient spraying onto crops. The fact that it is a liquid at room temperature makes it convenient to handle and store on farms. In the chemical synthesis industry, its solubility in both water and organic solvents makes it a versatile building block for the production of various compounds, including pharmaceuticals, dyes, and polymers.

Comparison with Other Cyanamide Solutions

When compared to 30% Cyanamide, 50% Cyanamide has a higher density, slightly higher boiling point, and lower freezing point. The higher concentration of Cyanamide in the 50% solution means that it has a more intense odor and is more reactive in chemical reactions. This higher reactivity can be an advantage in some applications where a more potent chemical is required, but it also requires more careful handling and storage.

Importance of Quality in Physical Properties

As a supplier of 50% Cyanamide, we understand the importance of maintaining consistent physical properties in our product. Any variation in density, solubility, or other physical characteristics can affect the performance of the chemical in end - use applications. We have strict quality control measures in place to ensure that our 50% Cyanamide meets the highest standards. This includes regular testing of samples for density, solubility, and other physical properties to ensure that they fall within the specified range.

Role of Raw Materials in Physical Properties

The quality of raw materials used in the production of 50% Cyanamide can have a significant impact on its physical properties. For example, the purity of the starting materials and the manufacturing process can affect the color, odor, and solubility of the final product. We source our raw materials, such as Calcium Carbide for Chemical, from reliable suppliers to ensure the high quality of our 50% Cyanamide.

Handling and Safety Considerations

Due to its physical properties, proper handling and safety precautions are necessary when working with 50% Cyanamide. The pungent odor and potential for irritation require the use of personal protective equipment (PPE) such as gloves, goggles, and respirators. The low freezing point means that in cold environments, appropriate heating or insulation should be provided to prevent freezing and potential damage to storage containers. The high solubility in water and organic solvents also means that spills can spread quickly and may require specific cleanup procedures.
