Copper extractants manufacturers will talk about what are extractants and common types

Purification is a unit operation to separate mixed substances by using the different solubility of components in the system in solution. There are two methods for purification:

Liquid liquid purification: use the selected organic solvent to separate certain components from the liquid mixed substances. The organic solvent should be immiscible with the liquid of the purified mixed substances, have selective solubility, and must have good heat resistance and chemical stability, and have small side effects and corrosion. For example, benzene is used to separate the phenol in the middle temperature coal tar; The olefins in the vacuum residue of crude oil are separated with organic solution.

Solid liquid purification, also known as leaching, uses organic solvents to separate the ingredients in solid mixed materials, such as tap water to soak glycogen from cabbage; Soak soybean oil from soybeans with alcohol to increase oil production; The tap water is used to extract the relevant ingredients from the traditional Chinese medicine to make the liquid extract, which is called "percolation" or "leaching".

Although purification is often used in organic chemistry experiments, its operation process does not lead to changes (or chemical changes) in the components of the purified chemical substances, so the extraction operation is a physical process.

Copper extractant manufacturer: What are the common extractants?

Extractants are chemicals that can produce extractants dissolved in organic phases with the purified substances. In hydrometallurgy, the role of extractants is to form extractants with the purified metals according to the chemical changes of mutual coordination to extract them into the organic phase, and to reverse the purification of the purified metals from the organic chemistry to the oil phase through certain chemical changes, so as to achieve the effect of metal material purification and aggregation.

1. Benzene:

A kind of nitrogen oxide compound, namely simple p-xylene, is a colorless transparent liquid with sweet taste, flammable, carcinogenic toxic side effects, and strong aromatic taste under normal temperature. It is insoluble in water, soluble in organic solution, and can also be used as organic solution.

2. Carbon tetrachloride;

It is a colorless toxic liquid, which can dissolve several chemicals such as fat and paint, and is easy to volatilize. It has the sweet taste of ether. Carbon tetrachloride and water are mutually insoluble and can be mutually soluble with alcohol, medical ether, ether and petroleum ether.

3. Ethanol:

It is an organic compound and a common monohydric alcohol. Alcohol is a flammable, volatile, colorless and transparent liquid under normal temperature and pressure, low toxicity, and pure liquid cannot be drunk at the same time; It has a special fragrance and is slightly irritating; It is slightly sweet and accompanied by the pungent food taste.

4. Kerosene:

It mainly refers to a kind of compound, which is a kind of light petroleum products. It is obtained by fractionation or cracking of pure natural crude oil or artificial oil. The single term "gasoline" generally refers to gasoline for lighting fixtures.
