Introduction to potassium bitartrate.
Potassium tartrate is an organic salt that is commonly used in food additives and chemical experiments. It is a salt produced by the reaction of tartaric acid with potassium hydroxide, and its chemical formula is khtartrate.
1. Physical and chemical properties of potassium hydrogen tartrate.
Potassium bitartrate is a white crystalline powder with a sour taste, soluble in water and ethanol, insoluble in ether. It has optical rotation, because there are two different conformations of tartaric acid in the molecular structure of tartaric acid, right-handed and left-handed, so the resulting potassium bitartrate also has two optical isomers, right-handed and left-handed. Among them, the optical rotation of potassium dextrophic tartrate is greater than that of potassium latrate, so what is commonly referred to as potassium dextrarate refers to potassium dextrarate.
Second, the production method of potassium hydrogen tartrate.
There are two main production methods of potassium bitartrate: one is the direct synthesis method, that is, the direct reaction of tartaric acid with potassium hydroxide to produce potassium bitartrate;The other is metathesis, that is, sodium tartrate is reacted with potassium chloride to produce potassium bitartrate and sodium hydroxide, and then the resulting potassium bitartrate is reacted with *** to obtain potassium bitartrate with higher purity.
3. Application fields of potassium bitartrate.
1.Food additives: potassium bitartrate is used as a stabilizer, thickener and acidulant in the food industry, and is widely used in the production of jams, jellies, juices, ice cream and other foods. At the same time, it is also one of the important raw materials for making wine, which can increase the taste and stability of wine.
2.Chemical experiments: In chemical experiments, potassium bitartrate is often used as a precipitant for the separation and purification of metal ions. For example, potassium bitartrate can be added to a solution containing barium ions to generate a less soluble barium tartrate precipitate, which can be separated from the solution by filtration and washing. In addition, potassium bitartrate can also be used in the preparation of certain organic compounds, such as metropine and amino sugars.
3.Other fields: In addition to food and chemistry, potassium bitartrate is also used in medicine, agriculture and environmental protection. For example, in the field of medicine, potassium bitartrate can be used in the preparation of certain drugs, such as calcium gluconate, etc.;In the agricultural field, potassium bitartrate can be used as a plant growth regulator;In the field of environmental protection, potassium bitartrate can be used to treat wastewater containing heavy metal ions.
Fourth, the safety of potassium bitartrate.
Potassium bitartrate is a relatively safe food additive that is widely used in the production of various types of food. However, excessive or long-term intake may have certain effects on health, so it is necessary to strictly control the amount and scope of use during use. In addition, the production and use of food additives also need to comply with relevant laws, regulations and standards to ensure food safety.
In conclusion, potassium bitartrate is widely used in many fields as an important organic salt and food additive. Knowledge of its properties, production methods, areas of application and safety can help to better recognize and use this substance. Leavening agent
