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 Anhydrous. Links are also available for other grades of Calcium Chloride
on this page and on other pages of our website
Calcium Chloride AnhydrousCalcium 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 Fused
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
this.
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 Calcium Chloride Dihydrate Crystals or Calcium Chloride Fused.
Calcium Chloride Dihydrate is having a melting point of
176C or there about. When its solution is evaporated in bottom
fired open pans. There is a percent gradient in the mass due to bottom
heating and top cooling. The material becomes fluffy and semi-solid at about
72% CaCl2. If the material is discharged at this point we can call this
material as Solid Fused Calcium Chloride.
If the evaporating solution
is not discharged at a little over 72% assay. It evaporates further to a
mass at >176oC and solidifies when the assay is >77%. If
the material is discharged at this point we can call this material as Porous
Fused Calcium Chloride.
The material that is a little
>77% assay will be solid at 200-500 C and to make Calcium
Chloride Anhydrous, this >77% material must be dried at >200C in a furnace. A day of drying is needed in the conventional furnace
to get fully anhydrous material.

Calcium Chloride, CaCl2,
users for desiccation purpose must understand the basic usability and
potency of Calcium Chloride. Calcium Chloride's water absorbing Potency is
very high at 75% to 80% assay. Theoretically, Calcium Chloride can be used
for water absorbing upto 50% assay. However practically Calcium Chloride can
be used for water absorbing upto 55-60% assay. For obvious reasons Calcium
Chloride Anhydrous is the only grade of Calcium Chloride that may be used
for desiccation purpose. Not many users understand this and wrongly compare
the prices of Calcium Chloride fused with that of Calcium Chloride Anhydrous
on pro-rata basis. Reliability of the vendor is also important as sampling
and analysis of Calcium Chloride may give false alarms.
Calcium Chloride Anhydrous CaCl2 is offered as
Solid lumps Powder Granules Tablets for various uses like Desiccation,
Diesel Drying, Gas Drying etc.
