Mixed xylenes
Mixed xylenes refers to a mixture of the xylenes plus ethylbenzene. The four compounds have identical empirical formulas C8H10. Typically the four compounds are produced together by various catalytic reforming and pyrolysis methods. [4] Occurrence and production.
ethylene glycol
Ethylene glycol is an organic compound with the formula₂. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid. It has a sweet taste, but is toxic in high concentrations. This molecule has been observed in […]
polypropylene
Polypropylene, also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is […]
Ethylbenzene
Ethylbenzene is an organic compound with the formula C₆H₅CH₂CH₃. It is a highly flammable, colorless liquid with an odor similar to that of gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material. In 2012, more than […]
Formaldehyde
Formaldehyde is an organic compound with the formula CH₂O and structure H−CHO. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde. It is stored as aqueous solutions, which consists mainly of the hydrate CH₂₂. It is the simplest of the aldehydes. As a precursor to many other materials and chemical compounds, in […]
polystyrene
Polystyrene is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of […]
Styrene
Styrene is a versatile aromatic hydrocarbon that is widely used in the production of various polymers and plastics. It is a colorless to yellowish, oily liquid with a sweet, floral odor. Styrene’s chemical formula is C8H8, and it is derived from benzene through a process called ethenylbenzene. One of the primary uses of styrene is […]
Dioctyl phthalate
Bis phthalate is an organic compound with the formula C₆H₄₂. DEHP is the most common member of the class of phthalates, which are used as plasticizers. It is the diester of phthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid is soluble in oil, but not in water.
polycarbonate
Polycarbonate is a versatile and durable thermoplastic polymer known for its excellent impact resistance, transparency, and heat resistance. It is produced through the reaction of bisphenol A (BPA) and phosgene, resulting in a high-performance material with a wide range of applications. Key characteristics and uses of polycarbonate include: 1. High Impact Resistance: Polycarbonate exhibits exceptional […]
Linear alkyl
Linear alkylbenzenes (sometimes also known as LAB s) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15, C 12 -C 13 and C 10 -C 13, for […]
