Product Description

Product Description

 

1. Definition

Anhydrous calcium chloride, with the chemical formula CaCl2, is a salt formed by the combination of calcium (Ca) and Cl ions. It is an inorganic compound known for its high hygroscopicity, meaning it readily absorbs moisture from the air. This property makes it useful in various applications, from drying agents to de - icers. Unlike hydrated forms, anhydrous calcium chloride contains no water molecules within its crystal structure, giving it a more concentrated and reactive nature.

2. Physical and Chemical Properties

Physical Properties: Anhydrous calcium chloride appears as a white, crystalline solid with a density of around 2.15 grams per cubic centimeter. It has a high melting point of approximately 772°C and a boiling point of about 1600°C. Highly soluble in water, it releases a significant amount of heat during dissolution, a process called exothermic dissolution.
Chemical Properties: It is chemically stable under normal conditions but can react with certain substances. For example, it forms complexes with NH3 and can react with some metal salts in metathesis reactions. Its strong affinity for water enables it to act as an effective desiccant.

3. Production Methods

1. From Natural Brines: One common method involves extracting it from natural brines rich in calcium and Cl compounds. After evaporation and purification processes, the brine solution yields anhydrous calcium chloride.
2. Reaction of HCl and Calcium Compounds: It can also be produced by reacting HCl with calcium carbonate or calcium hydroxide. The resulting solution is then evaporated and dried to obtain the anhydrous form.

4. Storage Methods

1. Moisture Protection: Store anhydrous calcium chloride in air - tight containers, like sealed plastic drums or bags, to prevent it from absorbing moisture from the environment, which can cause caking or dilution.
2. Separation: Keep it away from reactive substances such as strong bases (e.g., NaOH) and substances it can form complexes with to avoid unwanted chemical reactions. Store in a dry, cool place, away from direct sunlight.

Application

 

1. Moisture Absorption

Anhydrous calcium chloride has a strong affinity for water molecules, making it an ideal desiccant. In storage facilities, it protects electronics, books, and artwork from humidity - induced damage. For instance, museums use it to safeguard historical documents. It's also commonly placed in small sachets within product packaging to keep items dry during transit and on store shelves.

1. Efficient De - icing Agent

This compound is highly effective in de - icing applications. When spread on frozen surfaces like roads, bridges, and parking lots, it releases heat upon contact with ice, accelerating the melting process. Its ability to lower the freezing point of water ensures that ice doesn't re - form quickly, providing long - lasting protection against slippery conditions, which is crucial for road safety in winter.

1. Industrial Processes

In the oil and gas sector, anhydrous calcium chloride is added to drilling fluids to increase their density, preventing blowouts by balancing the pressure in the wellbore. In the production of polymers, it dries raw materials, ensuring a consistent quality of plastics and rubber products. It also helps in the purification of brine solutions in the chemical industry.

1. Food Industry Applications

It plays multiple roles in food production. In the cheese - making process, it helps coagulate milk proteins, leading to better - formed curds. For canned fruits and vegetables, it maintains firmness and texture. Additionally, it is used to enhance the flavor and stability of certain beverages, acting as a taste - enhancer and a clarifying agent.

1. Agricultural Uses

Farmers utilize anhydrous calcium chloride to suppress dust on unpaved farm roads, reducing the wear and tear on vehicles and improving visibility. When applied to crops, it can help reduce the risk of fungal diseases by minimizing the moisture on leaf surfaces. It also aids in soil stabilization, preventing erosion and improving water retention.

1. Concrete and Construction

In construction projects, especially in cold weather, anhydrous calcium chloride is added to concrete mixtures to accelerate the setting time. This allows for faster construction progress and reduces the waiting time between different stages of building. It also enhances the early - age strength of concrete, making structures more durable and stable from the start.

Logistics and Shipment
1. Packaging: Anhydrous calcium chloride is typically packaged in PP or PP+PE bag.
2. Transportation Conditions: During shipment, it should be kept in dry environments. Avoid transporting it together with substances that can react with it. Special attention should be paid to protecting the packaging to prevent spillage, especially during loading and unloading operations.
