Benzene (also called cyclohexatriene) is an organic chemical compound with the molecular formula C6H6. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals.
– Benzene is used mainly as an intermediate to make other chemicals, above all ethylbenzene, cumene, cyclohexane, nitrobenzene, and alkylbenzene and also used to make some types of rubbers, lubricants, dyes, detergents, drugs, explosives, and pesticides.
Ortho-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C6H4(CH3)2
– Petroleum contains about one weight percent xylenes. Most o-xylene is produced by cracking petroleum, which affords a distribution of aromatic compounds. o-Xylene is a colorless slightly oily flammable liquid.
– o-Xylene is largely used in the production of phthalic anhydride, which is a precursor to many materials, drugs, and other chemicals.
Para-Xylene (para-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flammable.
– p-Xylene is an important chemical feedstock. Among other industrial applications. It is a raw material in the large scale synthesis of various polymers. In particular it is a component in the production of terephthalic acid for polyesters such as polyethylene terephthalate (generally known as PET). It also may be polymerised directly to produce parylene.
Toluene, is a substituted aromatic hydrocarbon. its systematic IUPAC name is methylbenzene. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. Toluene is predominantly used as an industrial feedstock and a solvent.
Uses:
– Precursor to benzene and xylene, Produce polyurethane foam and TNT from Nitrotion of toluene, also Benzoic acid and benzaldehyde are produced commercially by partial oxidation of toluene.
– Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and disinfectants.
– Toluene can be used as an octane booster in gasoline fuels for internal combustion engines as well as jet fuel.
– In the laboratory, toluene is used as a solvent for carbon nanomaterials, including nanotubes and fullerenes, and it can also be used as a fullerene indicator.
Linear alkyl benzenes (sometimes also known as LABs) are a family of organic compounds with the formula C6H5CnH2n+1. They are mainly produced as intermediate in the production of surfactants, for use in detergent.
Application:
Linear alkyl benzene is sulfonated to produce linear alkyl benzene sulfonate (LAS), a biodegradable surfactant. LAS replaced branched dodecyl benzene sulfonates, which were phased out because they biodegrade more slowly.
