Introduction

Anhydrous calcium chloride is a colorless crystalline solid that absorbs moisture easily at room temperature. The following is a description of the properties, uses, preparation and safety information of anhydrous calcium chloride:Quality:anhydrous calcium chloride is colorless crystalline and has high solubility;It easily absorbs moisture in the air to form hydrates, which are soluble in water, release heat, and form a thermal solution.Anhydrous calcium chloride can dissolve or even solidify water at low temperatures and is often used as a dehumidifier.Use:Anhydrous calcium chloride is widely used in industrial and laboratory fields;Used as a dehumidifier, often used to reduce humidity and drying in hygroscopic environments;used as a snow melting agent and pavement de-icing agent;Acts as a dehydrating agent in the preparation of chemical reactions such as anhydrous liquid ammonia, anhydrous ethanol, and aluminum chloride.Preparation method:Anhydrous calcium chloride can be prepared by two main methods:Calcium chloride is produced through the reaction of sodium chloride and calcium hydroxide, and the water is removed by dehydration to prepare anhydrous calcium chloride.It is prepared by concentrated dehydration of calcium chloride solution in salt lake resources.Safety Information:anhydrous calcium chloride is irritating, so gloves and goggles should be worn when handling to avoid contact with skin and eyes;When anhydrous calcium chloride comes into contact with water, it will quickly absorb moisture and release a lot of heat, so be careful to avoid burns;When transporting and storing, avoid contact with water or moisture and keep it dry;avoid contact with acids, oxidants and other substances that are prone to reaction to avoid danger;If ingested or inhaled, seek medical attention immediately.
