13477-00-4 Usage
Description
Barium chlorate has the molecular formula of
Ba(ClO3)2 and a molecular weight of 304.229 g/mol. Its
density is 3.18 g/cm3 and its melting point is 413.9°C.
It is a white crystalline solid, a skin irritant and if
consumed can cause nausea, vomiting, and diarrhea.
Its CAS number is 13477-00-4. It is used in fireworks to
produce a green color. It also forms a monohydrate,
Ba(ClO3)2·H2O whose CAS number is 10294-38-9.
Shock-sensitive compounds are formed with organic
compounds, reducing agents, ammonia-containing
agents, and metal powders. The substance decomposes
violently on heating, producing oxygen, toxic fumes,
and causing fire and explosive hazards. This salt is
a strong oxidant and reacts with most combustible and
reducing materials.
Chemical Properties
Barium chlorate is a combustible, colorless to
white crystalline solid or powder.
Uses
Pyrotechnics, explosives, textile mordant, man-
ufacture of other chlorates.
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
A poison. Strong oxidizer, fire risk in con-
tact with organic materials.
Safety Profile
A poison. For fire and
explosion hazards, see CHLORATES.
Incompatible with Al, As, C, charcoal, Cu,
MnO2, metal sulfides, S4N4, organic matter,
P, S. See also BARIUM COMPOUNDS
(soluble).
Potential Exposure
It is used in fireworks and explosives
manufacture; in textile dyeing and in the manufacture of
other perchlorates.
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.
