Ethanol
Ethanol is a type of alcohol and the main component of wine. It is also commonly known as alcohol and liquor. It is neutral. Ethanol is flammable and is a commonly used fuel, solvent and disinfectant. It is also used in organic synthesis. Industrial alcohol contains a small amount of toxic methanol. Medical alcohol mainly refers to ethanol with a volume percentage concentration of about 75% (or a mass percentage concentration of 70%), and also includes other concentrations of alcohol widely u...Read more -
Chlorobenzene
Chlorobenzene, also known as chlorobenzene, is a colorless transparent liquid. It is volatile. It has the smell of benzene and slight anesthetic properties. This product can form an explosive mixture with air, and the explosion limit is 1Chemicalbook.83%~9.23% (volume fraction). The chlorine atoms in this product can be hydrolyzed to produce phenol. If hydrolyzed in an ammonia solution, aniline can be produced.Read more -
Benzyl chloride
Benzyl chloride, also known as benzyl chloride and chlorinated toluene, is a colorless liquid with a strong pungent odor. It is miscible with organic solvents such as chloroform, ethanol, and ether. It is insoluble in water but can evaporate with water vapor. Its vapor has a certain irritation to the mucous membrane of the eye and is a strong tear gas. At the same time, benzyl chloride is also an intermediate in organic synthesis and is widely used in the synthesis of dyes, pesticides, synthe...Read more -
Benzoic acid
Benzoic acid is also called benzoic acid. Its molecular formula is C6H5COOH. It is the simplest aromatic acid in which the carboxyl group is directly connected to the carbon atom of the benzene ring. It is a compound formed by replacing a hydrogen on the benzene ring with a carboxyl group (-COOH). It is a colorless, odorless flaky crystal. The melting point is 122.13℃, the boiling point is 249℃, and the relative density is 1.2659 (15/4℃). It sublimates rapidly at 100℃. Its vapor is highly irr...Read more -

Isophthalic acid
Isophthalic acid (IPA), also known as 1,3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance and chemical resistance, and can undergo salt formation, dehydration, hydrogenation, halogenation and other reactions. Its biggest use is as an intermediate chemical book in the production of unsaturated polyester resins, followed by the manufacture of polyester resins, alkyd resins (mainly used in coatings) and printing inks. In addition, it can also be used to reinf...Read more -
Ethylbenzene
Ethylbenzene, ethylbenzene, is a colorless liquid with an aromatic odor. It is insoluble in water, but soluble in most organic solvents such as ethanol and ether. It is relatively stable and is used in organic synthesis and as a solvent. It is highly irritating to the skin and mucous membranes, and has an anesthetic effect at high concentrations.Read more -

Styrene
Gradually polymerizes and oxidizes in the air, and an inhibitor [hydroquinone or tert-butylcatechol (0.0002% to 0.002%) as a stabilizer to delay its polymerization] must be added before it can be stored. In industry, it is an important monomer for synthetic resins, ion exchange resins, and synthetic rubber. Styrene can also undergo addition reactions unique to olefins. In industry, styrene can be obtained by catalytic dehydrogenation of ethylbenzene. In the laboratory, it can be obtained by h...Read more -
Xylene
Xylene (dimethylbenzene) is a colorless, transparent, aromatic liquid. It is the product of two hydrogen atoms on the benzene ring being replaced by methyl atoms. Its boiling point is 137-140°C. Xylene is divided into three isomers: o-xylene, m-xylene, and p-xylene according to the positions of the two methyl atoms. In industry, xylene refers to a mixture of the above isomers and ethylbenzene. The grade is generally the superior grade and first grade of the Chemicalbook of 3°C and 5°C distill...Read more
