Pure benzene
Benzene is the simplest aromatic hydrocarbon, with the molecular formula C6H6. In 1865, German chemist F.A. Kekulé proposed that benzene has a hexagonal structure with alternating single and double bonds, which has been used ever since. According to the hybrid orbital theory, the six π electrons in the benzene molecule are a whole, evenly distributed above and below the ring plane, and the structure of benzene can also be represented by a hexagon with a circle in it (see “Aromatic Hydro...Read more -
Tripropylene glycol
Tripropylene glycol is a colorless to light yellow liquid at room temperature and pressure. It has a certain solubility in water and is easily soluble in common organic solvents. It has the characteristics of low toxicity, low vapor pressure, and medium viscosity. It is a raw material that can be used in various radiation curing formulations. It usually undergoes an esterification reaction with acrylic acid to form tripropylene glycol diacrylate.Read more -

ETHANE
Ethane is the simplest hydrocarbon with a single carbon-carbon bond. It exists in natural gas (5% to 10%). It is a colorless, odorless, flammable gas that is soluble in benzene and ethanol (46 ml/100 ml at 4°C). Its vapor and air form an explosive mixture with an explosion limit of 3.0% to 12.5% (volume fraction).Read more -
Isobutylene
Isobutylene is also known as 2-methylpropylene. In industry, isobutylene is almost always obtained from refinery gas and cracking C4 fraction. The isobutylene content in refinery gas is generally 5% to 12%, and in cracking C4 fraction it is generally 20% to 30%.Read more -
1,3-Butadiene
1,3-Butadiene is an important petrochemical raw material and is widely used in synthetic rubber, synthetic resin and other fields. In the synthetic rubber industry, butadiene consumption accounts for 80% of the global butadiene consumption. Today, there are two main methods for the production of butadiene: ① butane butene dehydrogenation method; ② ethylene by-product extraction method. However, these two methods are heavily dependent on the use of petroleum resources. In the 1940s and 1950s, ...Read more -
PROPYLENE
Propylene is the second member of the olefin series, with a structural formula of CH2=CHCH3. It is an important organic industrial raw material after ethylene and benzene. It is generally separated from thermal cracking and catalytic cracking gases, and is also a by-product of light oil cracking to produce ethylene. The molecule contains unsaturated carbon-carbon double bonds, which can undergo addition reactions with hydrogen, halogens, hydrogen halides, etc., and can also undergo addition p...Read more -
Ethylene
Ethylene is a compound composed of two carbon atoms and four hydrogen atoms, with the two carbon atoms connected by a double bond. It is the simplest olefin, with a molecular formulhttps://www.huaxichemical.com/26734-2/a of CH2=CH2. It is a basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics (polyethylene and polyvinyl chloride), and synthetic ethanol (alcohol). It is also used to make vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, ethan...Read more -
Methyl tert-butyl ether
Methyl tert-butyl ether (MTBE) was once considered an irreplaceable high-octane gasoline component and was called the “third generation of petrochemicals” in the 1980s. Because it can increase the oxygen content of unleaded gasoline, make gasoline burn more fully, reduce the emission of harmful substances such as carbon monoxide and benzene, and can replace tetraethyl lead as an anti-knock agent, it meets the requirements for the production of high-octane unleaded gasoline, result...Read more -
