Muby Chemicals, established in 1976, is
the pioneer manufacturer of Chlorides, and particularly Calcium Chloride and
various other chemicals in
India. Mubychem Group
has several manufacturing facilities spread across
Western India. Muby chemicals know about Calcium
Chloride better than any other vendor in the world.
We manufacture Calcium Chloride in all grades like Solid, Fused, Porous,
Anhydrous, Brine, Solution, Dihydrate, Hexahydrate including pharmacopoeia grades
like IP BP USP EP and even in food grade FCC and in analytical reagent grade
AR or ACS. Below is the specifications and other details of Calcium Chloride Dihydrate. Links are also available for other grades of Calcium Chloride
on this page and on other pages of our website.
Calcium ChlorideCalcium Chloride, CaCl2, chemical compound that is crystalline, lumpy, or flaky,
is usually white, and is very soluble in water. A white deliquescent compound,
Calcium Chloride, CaCl2, which is soluble in water; m.p. 782°C. There are a
number of hydrated forms, including the monohydrate, CaCl2.H2O, the dihydrate,
CaCl2.2H2O (r.d. 0.84), and the hexahydrate, CaCl2.6H2O. The hexahydrate loses
4H2O at >30°C and the remaining 2H2O at 200°C). Large quantities of it are
formed as a byproduct of the Solvays Process or other manufacturing activities
and it can be prepared by dissolving calcium carbonate or calcium oxide in
hydrochloric acid. Solid calcium chloride is used in mines and on roads to
reduce dust problems, whilst the molten salt is the electrolyte in the
extraction of calcium. An aqueous solution of calcium chloride is used in
refrigeration plants.
Calcium Chloride, CaCl2, is hygroscopic; it rapidly absorbs water and is
used to dry gases by passing them through it. Calcium chloride is
commercially available usually as the dihydrate, CaCl2·2H2O; it is used to
melt ice on roads, to control dust, in brines for refrigeration, and as a
preservative in foods. It is also used in the monohydrate and hexahydrate
forms.
Calcium Chloride Dihydrate Crystals
The wording Calcium Chloride fused is loosely used for
Calcium Chloride having various amount of water with CaCl2 around its
dihydrate formula i.e. CaCl2.2H2O and it is ideally having 75.5% Calcium Chloride
with water as shown below:
CaCl2.2H2O
Ca(40) + Cl2(71) + 2H2O(36) make % of CaCl2 in it as
36/(40+71+36) = 75.51%
It is important for the user of Calcium Chloride fused
to understand the difference between Calcium Chloride Dihydrate Crystals and
Calcium Chloride Fused.
First stage at which manufactured
Calcium Chloride, CaCl2 is available is of Calcium
Chloride Solution say of 30-35%.. On further evaporation it can be converted
to Dihydrate Calcium Chloride Crystals or Calcium Chloride Fused.
Calcium Chloride Dihydrate is having a melting point of
176oC or there about at normal pressure. To get
Dihydrate Crystals CaCl2.2H2O, one must evaporate Calcium Chloride in a vacuum
evaporator maintaining temperatures of about 100 oC. Temperature
control is important to avoid formation of Calcium Chloride Tetrahydrate.
Calcium Chloride Dihydrate crystals are separated from the mother liquor by
high speed centrifuges and surface dried.
