Chemistry & industry
Applications
DescriptionCalcium chloride dihydrate (CaCl2﹒2H2O) is the hydrate form of calcium chloride. Calcium chloride is an inorganic compound consisting of calcium and chloride. It has various kinds of applications. For example, it can be used as a desiccant due to its high hygroscopicity; used for the deicing and dust control; for road surfacing; as brine for refrigeration plants, ice and cement; increasing the water hardness in the swimming pools; as a food additives; increasing the cell membrane permeability to facilitate the genetic transformation of cells; for the treatment of hypocalcemia in which the body requires a prompt increase in blood plasma calcium levels, For its production, it can be either produced directly from limestone or produced by the Solvary process as the by-product. In addition, it can also be obtained by purification from brine.
UsesCalcium chloride dihydrate is an odourless white solid in the form of small flakes. It is deliquescent (absorbs moisture from the air) and rapidly dissolves in water producing heat (exothermic). It has many industrial applications and is commonly used to prevent dusting, as a drying agent and to melt ice. It is used in swimming pools and aquariums as a pH buffer and a rapid source of calcium ions. Calcium Chloride is a general purpose food additive, the anhydrous form being readily soluble in water with a solubility of 59 g in 100 ml of water at 0°C. It dissolves with the liberation of heat. It also exists as calcium chloride dihydrate, being very soluble in water with a solubility of 97 g in 100 ml at 0°C. It is used as a firming agent for canned tomatoes, potatoes, and apple slices. In evaporated milk, it is used at levels not more than 0.1 percent to adjust the salt balance so as to prevent coagulation of milk during sterilization. It is used with disodium EDTA to protect the favor in pickles and as a source of calcium ions for reaction with alginates to form gels.
Usescosmetic ingredient. Food grade calcium chloride is used in various applications within the food and beverage industries. In the production of beer and soft drinks, CaCl2 is used as a source of calcium to regulate the hardness of water. In the production of cheese, CaCl2 is used as a source of calcium. CaCl2 is also used to increase the firmness of canned fruits and pickled vegetables. CaCl2 is also used as a secondary cooling agent in various processes that operate according to food regulations.
UsesPreparation of calcium standard solutions; electrolyte.
