Uses
Potassium tartrates is the acid potassium salt of tartaric acid occurring as crystals or powder.
Potassium tartrates is relatively poorly soluble having a solubility in 100 ml of water at 0.8 g at 25°c and 6.1 g at 100°c.
A 1% solution at 30°c has a ph of 3.4.
Chemical names are Potassium tartrates, potassium hydrogen tartrate, and potassium bitartrate.
Potassium tartrates functions to complex with heavy metal ions and to regulate ph; it can have a gentle laxative action if given at adequate levels.
The acidulant is used in chemical leavening to release carbon dioxide which produces the loaf volume.
Potassium tartrates has limited reactivity in the cold so when used in reduced-temperature batters it has little gas evolution during the initial mixing.
At room temperatures, Potassium tartrates has a relatively fast reaction rate.
Potassium tartrates functions as a taste regulator in sugar icing and in controlled crystallization of toffees and fondants by the regulated inversion of sucrose.
Potassium tartrates is used in baked goods, crackers, candy, and puddings.
Manufacture of potassium salts, medicine (cathartic), lab reagent.
Potassium tartrates is widely used in food, medicine, chemical industry, light industry, and other industries.
Potassium tartrates is mainly used to manufacture tartrates, such as potassium sodium tartrate, etc.
Potassium tartrates is used in the food industry as a beer foaming agent, food sour agent, flavoring agent, etc.
Preparation
Potassium tartrates is produced by the reaction of tartaric acid with potassium sodium tartrate (rochelle salt), and potassium sulfate, followed by filtration, purification, precipitation and drying.
Manufacturing
Potassium tartrates is produced by the reaction of tartaric acid with potassium sodium tartrate (rochelle salt), and potassium sulfate, followed by filtration, purification, precipitation and drying.
Preparation
preparation of Potassium tartrates:
1. according to the characteristics of potassium hydrogen tartrate soluble in hot water, soft water or distilled water twice as much as tartar or acid-reducing precipitate is first added to the reactor, and after heating to boiling, stirring is started and tartar or acid-reducing precipitate is added.
After all the material was dissolved, solid potassium carbonate was added.
Because the reaction is more intense, and a large amount of carbon dioxide gas is generated in the reaction process, in order to make the operation stable, in the addition of potassium carbonate, the batch should be added and the stirring should be strengthened.
The amount of potassium carbonate added was determined when the pH of the test system was 7 using litmus paper.
2. The neutral reaction material is filtered while hot, the filtrate is heated to boiling, and activated carbon is added for decolorization.
The activated carbon and other impurities were then removed by filtration.
The amount of activated carbon added to the material is colorless and transparent, generally 5% to 10% of the material.
3.after the decolorization of the material heating evaporation, when the concentration of potassium tartrates to meet the requirements of the material into the enamel plate, natural cooling crystallization at room temperature.
4. the crystal is dried, that is, the content of more than 99% to obtain potassium tartrate.
