Product Name: best supplier of potassium carbonate for industry
Molecular formula: K2CO3
Molecular weight: 138.2
CAS NO.: 584-08-7
HS CODE: 28364000
Potassium carbonate (K2CO3) is a white salt, soluble in water
(insoluble in
ethanol) which forms a strongly alkaline solution. It can be made
as the product
of potassium hydroxide's absorbent reaction with carbon dioxide. It
is
deliquescent, often appearing a damp or wet solid. Potassium
carbonate is used
in the production of soap and glass.

Applications
- for soap, glass, and china production
-
- as a mild drying agent where other drying agents, such as calcium
-
- chloride and magnesium sulfate, may be incompatible. It is not suitable
-
- for acidic compounds, but can be useful for drying an organic phase
if
-
- one has a small amount of acidic impurity. It may also be used to
dry
-
- some ketones, alcohols, and amines prior to distillation.
-
- in cuisine, where it has many traditional uses. It is an ingredient
in the
-
- production of grass jelly, a food consumed in Chinese and Southeast
-
- Asian cuisines, as well as Chinese noodles and moon cake. It is
used to
-
- tenderize tripe. German gingerbread recipes often use potassium
-
- carbonate as a baking agent, although in combination with hartshorn. It is
-
- however important that the right quantities are used to prevent
harm, and
-
- cooks should not use it without guidance.
-
- in the production of cocoa powder to balance the pH (i.e., reduce
the
-
- acidity) of natural cocoa beans; it also enhances aroma. The
process of
-
- adding potassium carbonate to cocoa powder is usually called
"Dutching"
-
- (and the products referred to as Dutch-processed cocoa powder), as
the
-
- process was first developed in 1828 by Coenrad Johannes van Houten, a
-
- Dutchman.
-
- as a buffering agent in the production of mead or wine.
-
- in antique documents, it is reported to have been used to soften hard
-
- water.
-
- as a fire suppressant in extinguishing deep-fat fryers and various
other B
-
- class-related fires.
-
- in condensed aerosol fire suppression, although as the byproduct of
-
- potassium nitrate.
-
- as an ingredient in welding fluxes, and in the flux coating on
arc-welding
-
- rods.
-
- as an aid to stability in neurons helping to maintain equilibrium.
-
- as an animal feed ingredient to satisfy the potassium requirements
of
-
- farmed animals such as broiler breeders.
