Organic matter: Most organic matter is soluble in benzene, but it is insoluble if it contains a large number of hydrophilic groups or simple organic salts... For example, sugars (insoluble) and sodium acetate (this can still be dissolved a little), methylamine hydrochloride...
But this is not absolute. For example, sodium benzoate can be soluble in benzene, which can be understood by the principle of similar dissolution. But the solubility is smaller than that of water. . .
In the case of inorganics, some covalent compounds can be soluble in benzene, such as tin tetrachloride, and halogen elements can be soluble in benzene. Due to the large conjugated bonds on benzene, there are also compounds that are able to coordinate with benzene to form coordination compounds. This has been talked about before, there are examples, I forgot =

Bromine is soluble in water and soluble in organic solvents (benzene, carbon tetrachloride, alcohol, etc.), because the solubility of bromine in water is less than that in organic solvents, it is usually possible to extract the elemental elements in water into organic solvents (benzene, carbon tetrachloride, etc.) that are insoluble in water (operation name is extraction).
Halogen elements: F, CL, BR, I, AT (radioactive elements) F2: light yellow-green.
Gas. Cl2: yellow-green.
Gas. BR2: Deep reddish-brown.
Liquid. Volatile.
i2: purple-black.
Solid. Easy to sublimate.
Physical Properties: FCLBR
IAT (not discussed).
Color: light to dark.
Density: from small to large.
Melting and boiling point: low to high.
Water solubility: F2 reacts violently with water, and the rest can be soluble in water and easily soluble in organic solvents.

Benzene is insoluble in water. Benzene is a carbon-based hydrogen organic compound, the simplest aromatic hydrocarbon.
The molecular formula is C6H6, which is a sweet, flammable, carcinogenic and toxic colorless transparent liquid with a strong aromatic odor at room temperature. It is insoluble in Zheng Sanshui, and the manuscript is easily soluble in organic solvents, and can also be used as an organic solvent itself.
Physical. Benzene is a colorless, sweet-smelling transparent liquid at room temperature, which is less dense than water and has a strong aromatic odor. The boiling point of benzene is, and the melting point is. Benzene is less dense than water, with a density of , but its molecular weight is heavier than water.
Benzene is insoluble in water, and the maximum amount of benzene dissolved in 1 liter of water is dissolved; But benzene is a good organic solvent with a strong ability to dissolve organic molecules and some non-polar inorganic molecules, except glycerol and ethylene glycol.
and other polyols can be miscible with most organic solvents, except for iodine and sulfur slightly soluble, inorganic.
Insoluble in benzene.

1.Organic solvents containing benzene, toluene and other benzene are: benzene.
2.Toluene. 3.Xylene.
4.Trimethylbenzene.
5.Tetraxylene.
6.Mixed aromatics.
7.Crude toluene from CNOOC.
8.In addition, some pharmaceutical companies use benzene, toluene and other solvents, and the purification solvent after waste and redistillation will also contain a small amount of benzene or toluene.
9.Note: These are aromatic hydrocarbons cut off solvents of different distillation ranges, containing unequal amounts of benzene and toluene, respectively.

Benzene is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent itself. Benzene is a hydrocarbon organic compound, that is, the simplest aromatic hydrocarbon, the molecular formula is C6H6, at room temperature is a sweet, flammable, carcinogenic and toxic colorless transparent liquid, with a strong aromatic odor.
Benzene substance structureThe benzene ring is the simplest Wu Yufang ring, which is composed of six carbon atoms to form a six-membered ring, each carbon atom is connected to a group, and the six groups of benzene are all hydrogen atoms.
However, experiments have shown that benzene cannot discolor bromine water or acidic KMNO4, which means that there is no carbon-carbon double bond in benzene. It has been proved that the carbon atoms on the benzene ring backbone are not arranged by single and double bonds as previously known (proposed by Kekule), and that the bonds between every two carbon atoms are the same, and are connected by a bond that is neither double nor single (major bond).

Benzene is a chemical substance
Benzene is a commonly used organic solvent and is the simplest aromatic hydrocarbon in composition. At room temperature, benzene is a colorless, sweet-smelling, oily transparent liquid, with a density less than water and a strong special odor. Flammable, flammable at room temperature.
Benzene (CH) is a commonly used organic solvent and is an aromatic hydrocarbon with the simplest composition. At room temperature, benzene is a colorless, sweet, oily transparent liquid, which is less dense than water and has a strong special odor. It is flammable and highly flammable at room temperature.
Benzene is a hydrocarbon, the simplest aromatic hydrocarbon, which is a sweet, flammable, carcinogenic and toxic colorless transparent liquid at room temperature, and has a strong aromatic odor. It is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent in itself. The ring system of benzene is called benzene ring, and the structure of benzene ring after removing a hydrogen atom is called phenyl group, which is expressed by pH, so the chemical formula of benzene can also be written as phh.
Benzene is a basic raw material for petrochemical industry, and its output and technical level of production are one of the indicators of the development level of a country's petrochemical industry. A hydrocarbon, the simplest aromatic hydrocarbon, is a sweet, flammable, carcinogenic and toxic colorless transparent liquid at room temperature with a strong aromatic odor. It is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent in itself.

Benzene is a carbonation deficiency of reuka compound is the simplest aromatic hydrocarbon, at room temperature is a sweet, flammable, carcinogenic and toxic colorless transparent liquid, and with a strong aromatic odor, it is insoluble in water, soluble in organic solvents, itself can also be used as an organic solvent. The ring system of benzene is called benzene ring, and the structure of benzene ring after removing a hydrogen atom is called this group, which is represented by p h, so the chemical formula of benzene can also be written as p h h. Benzene is a basic raw material for petrochemical industry.

At a certain temperature), (the mass of a solid substance that dissolves when it reaches saturation in 100 g of solvent) is called the solubility of the substance. Solubility is a physical quantity that (quantitatively) indicates the solubility of a substance. The higher the solubility value, the more solubility (stronger) the substance is at that temperature.
Different substances have different characteristics, what substance do you want to ask?
Matter (Buddhist interpretation).
The definition of matter is limited by the definition of the universe to the range of values of the moment, and the instantaneous state of the universe is given after ignoring the increment of time. >>>More
What is biochar: In a low-oxygen environment, wood, grass, corn stalk or other crop waste is carbonized by high-temperature cracking. This kind of charcoal, which is formed by plants and aims to fix the element carbon, is called "biochar" by scientists. >>>More
