💡 Commercial Applications
Calomel, also known as mercury(I) chloride, has a variety of commercial and industrial applications. It is commonly used in the production of chlorine and caustic soda through the chloralkali process. Additionally, calomel is utilized in the manufacturing of glass and as a catalyst in some chemical reactions.
In the realm of drug and medication applications, calomel has been historically used as a purgative and a diuretic. It has also been employed in the treatment of syphilis and as an antiseptic agent. Although its use has declined in modern medicine due to its toxic nature, calomel was once a common remedy for various ailments.
⚗️ Chemical & Physical Properties
In its natural form, Calomel appears as a white crystalline solid with no distinct odor.
The molar mass of Calomel is approximately 234.41 g/mol, and its density is around 7.15 g/cm³. These values are considerably higher compared to common food items such as sugar and salt, which have lower molar masses and densities.
Calomel has a melting point of 426°C and a boiling point of 1,357°C. These values are significantly higher than those of common food items like butter and chocolate, which have lower melting and boiling points.
Calomel has limited solubility in water and typically has low viscosity. This differs from common food items like sugar or salt, which are highly soluble in water and have varying levels of viscosity.
🏭 Production & Procurement
Calomel, also known as mercurous chloride, is a chemical compound that has long been used in various medical and industrial applications. The production of Calomel involves a reaction between mercury and hydrochloric acid, resulting in the formation of a white crystalline powder with a chemical formula of Hg2Cl2. This compound is then further processed and purified to meet specific standards for different uses.
Calomel can be procured from specialized chemical manufacturers who produce it in large quantities for various industries. The compound is typically packaged in sealed containers to prevent contamination and ensure its purity during transportation. Due to its toxic nature, Calomel requires careful handling and storage to avoid environmental hazards and health risks.
Transporting Calomel requires compliance with strict regulations governing the transportation of hazardous chemicals. Specialized containers are used to transport Calomel safely, minimizing the risk of exposure to the compound during transit. Additionally, proper labeling and documentation are essential to ensure that the shipment is handled correctly and reaches its destination without incident.
