Benzene (cyclohexa-1, 3) is the basis of a group of hydrocarbons referred to as “aromatics”. It is a clear colorless liquid, with a characteristic aromatic smell. Benzene is produced worldwide in substantial quantities, and because it is very easy to transport by ship, it is traded internationally.
Mixed xylenes are the second-most-important aromatic product in
Mixed xylenes are the second-most-important aromatic product in terms of world consumption for chemical manufacture, ranking behind benzene and ahead of toluene. Mixed xylenes refers to the equilibrium mixture of four isomers with the same C8H10 chemical formula. The isomers in order of natural occurrence are meta-xylene, ortho-xylene, para-xylene, and
Para-Xylene is made by separating compound xylene, and
Para-Xylene is made by separating compound xylene, and is a transparent liquid with no color. It is harmful to the body. The product has high value as it is used to produce terephthalic acid, which becomes raw material for polyester, fiber, PET bottles, and films.
Polycarbonates (PC) are a group of thermoplastic polymers
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent.
Toluene is an aromatic compound that has many applications in chemical industries. Toluene, with C7H8 chemical formula, is found a lot in coal tar and with less quantity, in crude oil. Toluene is a colorless and flammable liquid, which is soluble in alcohol, benzene and ethers, but not water. The
