Esters (Plasticizers)
Phthalic anhydride is produced by oxidizing naphthalene. Phthalic anhydride is used in the production of colouring agents, pharmaceuticals, resin and plasticizers for PVC. Phthalic Anhydride molten/flakes
Benzene
Benzene is the main component of crude benzol that is formed by washing of coke gas in a coke plant. Highly refined benzene is produced by hydrogenation refining and subsequent distillation of benzol. Benzene forms a primary element in many polymers used in daily life such as polystyrene, PET, nylon, polycarbonates, polyurethanes, etc...
Aromatic solvents
Toluene, xylene and solvent naphtha are secondary components of coke benzol. These substances and their substrates are derived from crude benzol by hydrogenation refining and distillation. Toluene is one of the most commonly used organic solvents. Toluene is used as a solvent in paints and varnishes; it is also used during production of rubber products, adhesives, silicone mastics and sealants. It also finds several medical applications.
Sulfur and bicarbonate
Sulphur and sodium bicarbonate are byproducts formed during production of other substances that find wide application in manufacturing of varied chemical products. Sodium Bicarbonate – aqueous solution (20–25%)
Phenols, cresols, tar acids
Oil (along with other substances) with a high phenolic content is produced by distillation of tar oils. By extracting acidic phenols and subsequent distillation of this oil, pure phenol and mixtures of phenols, cresols and xylenols are produced. Phenol is the basic raw material of bisphenol A, the condensation of which with other substances produces polycarbonates and epoxy resins. Phenol, cresols and xylenols are the basic ingredients for phenolic resins.
Naphthalene
Naphthalene is present in coal tar in the amount of about 10%. Naphthalene oil is separated from the tar by distillation, which is further purified by distillation and refining after the removal of phenols. The resulting product is produced in two qualities, technical naphthalene with a naphthalene concentration of over 97% and pure naphthalene with a purity of over 99%.
Aromatic specialties
Oil with a high concentration of anthracene and carbazole is produced by distillation of tar oils, among other substances. Pure anthracene and carbazole substances are produced by subsequent crystallization in combination with highly effective vacuum distillation. Pure carbazole is used to make pigments and pharmaceuticals.
