염화칼슘 C화학적 특성, 용도, 생산


화학식은 CaCl2이다. 복염으로서 타키하이드라이트 등의 광물로서 산출되며 바닷물 속에 0.15% 함유되어 있다. 염화칼슘(CaCl2)은 분자식에서 보는 것처럼 칼슘이온 1개와 염화이온 2개의 비율로 구성된 화학물질이다. 상온에서 고체이고 물에 잘 녹으며 하얀색을 띤다. 염화칼슘은 낮은 온도에서도 물에 잘 녹는다(0℃에서 약 60 g/100 mL). 공기에 포함된 수분을 흡수하기 때문에 밀폐된 공간의 수분 제거 혹은 순수한 기체에 포함된 수분 제거에도 염화칼슘을 이용한다. 염화칼슘의 제습 효과는 실리카 겔의 제습 효과보다 훨씬 뛰어나고, 습도가 낮은 조건에서도 그 효과가 좋다. 그래서 수분에 의해 변질되기 쉽고, 매우 민감한 화학물질을 밀봉이 된 건조용기에 염화칼슘과 함께 보관하면 화학물질이 수분에 의해서 변질되는 것을 막을 수 있다


무수물(無水物, anhydride. 분자 중에서 산소와 수소가 물의 비율대로 떨어져 나간 무기 화합물)은 습기를 흡수하는 성질이 있다. 그리고 조해성(습기를 흡수한 후 스스로 녹는 성질)이 있다. 따라서 무수물은 건조한 환경에서 밀봉하여 보관해야 한다. 물과 알코올, 아세톤에 잘 녹는다. 전기 분해하면 칼슘과 염소로 나뉜다.


무수염 및 2수 화염은 각종 물질의 건조제로 사용 되며 수용액은 냉동기용 및 얼음 제조용의 냉매로 쓰인다. 또 콘크리트에 혼합하여 동결 방지에 사용되며 집진제, 목재, 직물의 방화제,식품, 목제의 방부제등에 사용 된다

제품 소개

말 그대로 염소와 칼슘의 화합물로, 화학식은 CaCl2다. 수용성이며, 상온에서 흰색의 고체다.

화학적 성질

Calcium chloride, CaC12, is colorless deliquescent solid that is soluble in water and ethanol. It is formed from the reaction of calcium carbonate and hydrochloric acid or calcium hydroxide and ammonium chloride. It is used in medicine, as an antifreeze, and as a coagulant.

화학적 성질

Calcium chloride occurs as a white or colorless crystalline powder, granules, or crystalline mass, and is hygroscopic (deliquescent).

물리적 성질

White crystal, powder or flake; highly hygroscopic; the compound and its solutions absorb moisture from the air at various rates depending on calcium chloride concentrations, relative humidity and vapor pressure of water in the air, temperature, surface area of exposed material, and the rate of air circulation; at 40% and 95% relative humidity and 25°C, one gram anhydrous calcium chloride may absorb about 1.4 g and 17 g water, respectively. (Shearer, W. L. 1978 . In Kirk-Othmer Encyclopedia of Chemical Technology, 3rd ed., vol. 4, pp. 432-6. New York: Wiley Interscience); density 2.15, 2.24, 1.85, 1.83 and 1.71 g/cm3 for the anhydrous salt and its mono-, di-, tetra- and hexahydrates, respectively; anhydrous salts melts at 772°C, while the mono-, di-, tetra- and hexahydrates decompose at 260°, 175°, 45.5° and 30°C, respectively; the anhydrous salt vaporizes at 1,935°C; highly soluble in water, moderate to high solubility in alcohol.


Calcium chloride may be found in nature as the mineral tachhydrite, CaCl2?2MgCl2?12H2O. It also is found in other minerals. Its concentration in sea water is about 0.15%.
Calcium chloride has several industrial applications. The major applications of this compound are in deicing of roads, dust control, imparting stability to roads and buildings, and to improve traction in tractor tires. It is mixed with ice to make freezing mixtures. Hexahydrate mixed with crushed ice can lower the temperature of the cooling bath to below -50°C. It also is used as a desiccant for dehydrating gases and liquids. It is added to cement in various proportions to manufacture different types of concrete. Other uses are in adhesives, to lower gel temperatures, and as a calcium source in liquid feed supplements for dairy cattle. Also, the compound is used to control particle size development and reduce coalescence in plastics.


Calcium chloride is one of the most versatile of the basic chemicals.It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in concrete. The anhydrous salt is also widely used as a desiccant, where it will absorb so much water that it will eventually dissolve in its own crystal lattice water (water of hydration). It can be produced directly from limestone, but large amounts are also produced as a by-product of the “Solvay Process” (which is a process to produce soda ash from brine).
Calcium chloride is also commonly used as an additive in swimming pool water as it increases the “calcium hardness” value for the water.Other industrial applications include use as an additive in plastics, as a drainage aid for wastewater treatment, as an additive in fire extinguishers, as an additive in control scaffolding in blast furnaces, and as a thinner in “fabric softeners”.
Calcium chloride is commonly used as an “electrolyte” and has an extremely salty taste, as found in sports drinks and other beverages such as Nestle bottled water. It can also be used as a preservative to maintain firmness in canned vegetables or in higher concentrations in pickles to give a salty taste while not increasing the food’s sodium content. It is even found in snack foods, including Cadbury chocolate bars.In brewing beer, calcium chloride is sometimes used to correct mineral deficiencies in the brewing water. It affects flavor and chemical reactions during the brewing process, and it can also affect yeast function during fermentation.
Calcium chloride can be injected as intravenous therapy for the treatment of “hypocalcemia” (low serum calcium). It can be used for insect bites or stings (such as Black Widow spider bites), sensitivity reactions, particularly when characterized by “urticaria” (hives).


Obtained as a by-product in the manufacture of potassium chlorate. The white crystals, soluble in water and alcohol, are deliquescent and must be kept in a well-stoppered bottle. Calcium chloride was used in iodized collodion formulas and in collodion emulsions. It was also an important desiccating substance used in tin calcium tubes designed to store presensitized platinum papers.


calcium chloride is an astringent. It also helps improve the reaction among certain ingredients used in cosmetic formulations. This inorganic salt is no longer commonly used in skin care products and is being replaced with potassium chloride.


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% to adjust the salt balance so as to prevent coagulation of milk during sterilization. it is used with disodium edta to protect the flavor in pickles and as a source of calcium ions for reaction with alginates to form gels.


For the treatment of hypocalcemia in those conditions requiring a prompt increase in blood plasma calcium levels, for the treatment of magnesium intoxication due to overdosage of magnesium sulfate, and used to combat the deleterious effects of hyperkalemi


Calcium chloride is highly hygroscopic and is often used as a desiccant.

제조 방법

Calcium chloride is obtained as a by-product in the manufacture of sodium carbonate (soda ash) by ammonia-soda (Solvay) process. The process involves the reaction of sodium chloride with calcium carbonate and ammonia. Calcium chloride is currently produced in bulk amounts by evaporation of natural underground brines. In the laboratory, calcium chloride can be prepared by treating limestone with hydrochloric acid followed by evaporation of solution to obtain crystals. The crystals are dehydrated to obtain anhydrous salt. Calcium oxide or hydroxide may be used instead of carbonate.

생산 방법

Calcium chloride is a principal byproduct from the Solvay process.


calcium chloride: A white deliquescentcompound, CaCl2, which issoluble in water; r.d. 2.15; m.p.782°C; b.p. >1600°C. There are anumber of hydrated forms, includingthe monohydrate, CaCl2.H2O, the dihydrate,CaCl2.2H2O (r.d. 0.84), andthe hexahydrate, CaCl2.6H2O (trigonal;r.d. 1.71; the hexahydrate loses4H2O at 30°C and the remaining2H2O at 200°C). Large quantities of itare formed as a byproduct of theSolvay process and it can be preparedby dissolving calcium carbonateor calcium oxide in hydrochloricacid. Crystals of the anhydrous saltcan only be obtained if the hydratedsalt is heated in a stream of hydrogenchloride. Solid calcium chloride isused in mines and on roads to reducedust problems, whilst the molten saltis the electrolyte in the extraction ofcalcium. An aqueous solution of calciumchloride is used in refrigerationplants.

Long term exposure of Calcium chloride solution upon a zinc coated galvanized iron vessel caused slow evolution of hydrogen which ignited and exploded [Bretherick, 5th Ed., 1995].


Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes (particularly by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes mild irritation; strong solutions can cause marked irritation, even a superficial burn.

Pharmaceutical Applications

The main applications of calcium chloride as an excipient relate to its dehydrating properties and, therefore, it has been used as an antimicrobial preservative, as a desiccant, and as an astringent in eye lotions.
Therapeutically, calcium chloride injection 10% (as the dihydrate form) is used to treat hypocalcemia.
