Uses
Used in Pyrotechnics:
Barium chlorate monohydrate is used as a color-producing agent in pyrotechnics, specifically to create a green color in fireworks. Its strong oxidizing properties make it an effective component in these applications.
Used in Explosives:
Due to its shock sensitivity and ability to form compounds with various materials, barium chlorate monohydrate is utilized in the manufacturing of explosives. Its strong oxidizing nature contributes to the explosive properties when combined with other compounds.
Used in Textile Industry as a Mordant:
Barium chlorate monohydrate serves as a mordant in the textile industry, where it helps to fix dyes to fabrics, ensuring colorfastness and durability.
Used in the Manufacture of Other Chlorates:
Barium chlorate monohydrate is also used in the production of other chlorate compounds, which have various applications in different industries.
Preparation
Barium chlorate can be produced through a double
replacement reaction of barium chloride and sodium
chlorate:
BaCl2＋ 2NaClO3→Ba(ClO3)2＋ 2NaCl
It can also be produced through a more complicated
process involving barium carbonate and ammonium chlorate, both of which are produced in situ. There are
four separate reactions used to produce this salt:
BaCl2＋ Na2CO3 →BaCO3＋ 2NaCl or BaCl2＋2NaHCO3 →BaCO3＋ 2NaCl＋ H2O＋ CO2(1)
In a separate step, ammonium chlorate is produced
by reaction of tartaric acid, C4H6O6, to produce ammonium
bitartrate. This is then reacted with potassium
chlorate which produces potassium bitartrate and
ammonium chlorate:
C4H6O6＋NH4OH→NH4C4H5O6＋H2O (2)
NH4C4H5O6＋ KClO3→KC4H5O6＋NH4ClO3 (3)
The produced barium carbonate is then reacted with
ammonium chlorate:
2NH4ClO3＋ BaCO3＋ heat→Ba(ClO3)2＋ 2NH3＋H2O＋ CO2 (4)
The final product is obtained without having to handle
the chlorate solutions or product before the final product
is obtained.
It can also be produced via the Liebig process similar
to that of the strontium homologue which consists of
passing chlorine gas through a solid such as Ba(OH)2:
6Ba(OH)2＋ 6Cl2→5BaCl2＋ Ba(CIO3)2＋ 6H2O
However, separating the two salts remains problematic
since both are soluble in water. It is for
this reason that the Liebig method is not used for the
commercial production of barium chlorate.
Hazard

Shipping
UN1445 Barium chlorate, Hazard Class: 5.1;
Labels: 5.1—Oxidizer, 6.1—Poisonous materials.
Incompatibilities
A strong oxidizer. When heated above
250° C, it begins to give off oxygen and will increase risk
of fire. Barium chlorate is a reactive chemical and is an
explosion hazard. Violent reaction may occur with reducing
materials; strong acids; powdered metals. Contact with
combustible materials will increase activity in fire.
Waste Disposal
Use large volumes of reducing
agent (bisulfite or ferrous salt) solutions. Neutralize and
flush to sewer with large volumes of water.
Check Digit Verification of cas no
The CAS Registry Mumber 13477-00-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13477-00:
(7*1)+(6*3)+(5*4)+(4*7)+(3*7)+(2*0)+(1*0)=94
94 % 10 = 4
So 13477-00-4 is a valid CAS Registry Number.
