توضیح اجمالی:
Diethanolamine (DEA), also known by its trade names Iminodiethanol or DEA Base, is an organic compound widely used in the chemical and industrial sectors. With the molecular formula C4H11NO2, DEA belongs to the ethanolamine family of amines, which are both alcohols and amines, making them highly versatile in chemical reactions.
This clear to pale yellow, viscous liquid is hygroscopic and has a mild ammonia-like odor. DEA is completely miscible with water, alcohol, and most polar solvents, which explains its extensive use across multiple industries.
Chemical and Physical Properties of DEA
These characteristics make DEA a valuable intermediate for formulating surfactants, emulsifiers, and corrosion inhibitors.
Applications of Diethanolamine
1.Surfactants and Detergents
DEA is a key raw material in the production of surfactants, such as DEA-based fatty acid amides (cocamide DEA), which are widely used in shampoos, dishwashing liquids, and liquid detergents for their excellent foaming and emulsifying properties.
2.Gas Treatment
DEA solutions are used in gas sweetening processes, particularly in removing acid gases such as H₂S and CO₂ from natural gas and refinery streams. Its ability to form reversible bonds with acidic gases makes it a cost-effective scrubbing agent.
3.Cosmetics and Personal Care
DEA derivatives are used in shampoos, lotions, and creams as emulsifiers and viscosity enhancers. However, regulatory authorities have set strict guidelines on DEA concentration due to concerns over nitrosamine formation.
4.Agricultural Chemicals
DEA acts as a neutralizing and solubilizing agent in herbicide formulations, improving the efficiency and stability of active ingredients.
5.Industrial Applications

What is Jet Fuel?
Jet fuel is a specialized type of aviation fuel derived from the middle distillates of crude oil, primarily composed of hydrocarbons in the C8–C16 range. It is engineered to power gas-turbine engines in aircraft, including commercial airplanes, cargo jets, and helicopters. Unlike standard kerosene, jet fuel undergoes strict refining processes and quality controls to meet the demanding conditions of aviation, such as high altitudes, low temperatures, and extreme engine performance.
Kerosene, also referred to as paraffin oil, is a middle distillate petroleum product obtained through fractional distillation of crude oil at temperatures between 150°C and 275°C (300–525°F). It is a clear to pale yellow hydrocarbon liquid that is less volatile than gasoline but lighter than diesel, making it an essential energy carrier with diverse applications across aviation, industry, and households.
With an average energy density of 43 MJ/kg, kerosene provides efficient combustion and relatively clean performance compared to heavier petroleum fuels. Its flash point ranges between 37°C and 65°C, making it safer to store and handle than gasoline.

Diesel fuel, also known as gas oil or distillate fuel, is a petroleum product obtained through the fractional distillation of crude oil between 200°C and 350°C at atmospheric pressure. It consists mainly of hydrocarbons containing C10–C20 carbon chains, including paraffins, naphthenes, and aromatic compounds.
Diesel is widely recognized for its high energy density, efficiency in compression ignition engines, and versatility across industries. It is one of the most consumed petroleum products globally. According to the International Energy Agency (IEA), diesel accounts for approximately 28–30% of total global oil demand, making it a critical fuel for the global economy.
Fuel Oil: Definition, Properties, and Global Applications
What is Fuel Oil?
Fuel oil, also known as heavy oil or residual oil, is a petroleum fraction obtained as a by-product during the distillation of crude oil. It is a viscous, dark-colored liquid hydrocarbon that remains after lighter fractions such as gasoline, kerosene, and diesel are removed from crude oil. Chemically, fuel oil is a mixture of long-chain hydrocarbons containing carbon, hydrogen, small amounts of sulfur, nitrogen, oxygen, and trace metals. Its energy density makes it one of the most important fuels in global energy consumption.
According to the International Energy Agency (IEA), fuel oil accounts for nearly 10–12% of total world oil demand, with major consumption in shipping, power generation, and industrial heating.
Bitumen: Definition, Properties, and Main Grades
What is Bitumen?
Bitumen, often referred to as asphalt, is a highly viscous hydrocarbon material derived as a by-product of crude oil refining or found in natural deposits. Its unique combination of adhesion, waterproofing ability, and durability makes it indispensable in road construction, pavement surfacing, and industrial applications.
Globally, more than 85% of bitumen consumption is allocated to road and highway construction, while the rest is used in roofing, waterproofing membranes, and industrial products.
Plasticizers are vital chemical additives used to increase the flexibility, workability, and durability of polymer materials—most notably polyvinyl chloride (PVC). By embedding themselves between polymer chains, plasticizers reduce intermolecular forces, making materials softer, more elastic, and easier to process.
They play a crucial role across multiple industries, from construction and automotive to medical devices, packaging, and consumer goods.
Among the wide range of available plasticizers, three products dominate the global market due to their excellent balance of performance, cost-efficiency, and safety standards:
DOP (Dioctyl Phthalate), DINP (Diisononyl Phthalate), and DOTP (Dioctyl Terephthalate).

Ethylene derivatives are the industrial compounds produced from ethylene (C₂H₄) that form the backbone of modern plastics, fibers, coatings and many specialty chemicals. Common derivative families include ethylene oxide → glycols (MEG, DEG, TEG), ethylene dichloride (EDC) → vinyl chloride (VCM) → PVC, and vinyl acetate monomer (VAM) for adhesives and paints. Demand for these derivatives is closely linked to global petrochemical feedstock flows (steam-cracker and PDH runs), end-use growth (packaging, textiles, construction, automotive) and regional capacity additions.
Propylene derivatives represent one of the most vital families of petrochemical intermediates derived from propylene (C₃H₆) — a key building block in the global chemical industry. Propylene is primarily obtained from steam cracking of hydrocarbons or as a byproduct of fluid catalytic cracking (FCC) in refineries.

Cyclohexane (CAS 110-82-7) is a colorless, non-polar cycloalkane (C₆H₁₂) widely produced and traded as a petrochemical intermediate. It is principally manufactured by hydrogenation of benzene and serves as a primary feedstock to produce cyclohexanol / cyclohexanone (KA oil), which in turn are converted to adipic acid and caprolactam — the essential intermediates for nylon-6,6 and nylon-6 polymers. Because of its role in the nylon value chain, cyclohexane demand closely follows global polymer, textile and automotive markets.
Phenol (CAS 108-95-2) is one of the most important aromatic intermediates in the chemical industry. Although it appears simple chemically, phenol occupies a central place in global petrochemical value chains — primarily as the feedstock to make bisphenol A (BPA), phenolic resins, and, via hydrogenation routes, intermediates for nylon and other engineering plastics.

Cumene (IUPAC: isopropylbenzene, CAS 98-82-8) is a colourless, aromatic hydrocarbon that plays a central role in the petrochemical value chain. Nearly all industrial-scale cumene is used as a feedstock to make cumene hydroperoxide, the intermediate for phenol and acetone production — two high-volume chemicals used to manufacture plastics, resins and fibers.
What is Styrene Monomer?
Styrene monomer (CAS 100-42-5)—also called phenylethene or vinylbenzene—is a clear, colorless to pale yellow liquid with a sweet aromatic odor. It is a reactive aromatic hydrocarbon and an essential petrochemical building block used primarily as the monomer feedstock for styrenic polymers (polystyrene, ABS, SAN and many copolymers). Styrene is shipped commercially in stabilized form (with inhibitors added) to prevent premature polymerization during transport and storage.
Benzene (CAS No. 71-43-2) is the archetypal aromatic hydrocarbon: a colorless, volatile liquid with the molecular formula C₆H₆ and a characteristic sweet odor. It is a fundamental petrochemical feedstock rather than an end-use consumer product. Industrial benzene is used almost exclusively as a raw material in the manufacture of derivatives such as ethylbenzene (→ styrene), cumene (→ phenol & acetone), cyclohexane (→ nylon intermediates) and many other high-value intermediates.
