C-Chem performs precision separation of usable components of coal tar, which contains well over a thousand chemical compounds.
The Company's proprietary catalyst and other technologies give it high productivity not possessed by other companies.
Coal tar contains main chemical compounds that express such functions as photoresponsiveness, heat resistance, electrical conductivity, chromogenicity, corrosion resistance, and bioactivity that are not found in synthetic products.
C-Chem has commercialized and supplied chemical compounds of differing properties to a wide range of fields from intermediates for medical and agricultural chemical raw materials and pigment raw materials to industrial chemical raw materials. The mission of C-Chem is to utilize its world-class gas-phase oxidation catalyst technology and proprietary precision separation and refining technology to maximum use of the earth's precious resources.
Gas-phase oxidation catalyst technology provides unmatched production capability.
Phthalic anhydride is mainly used as a plasticizer raw materials for vinyl chloride resin. Also, phthalic anhydride is widely used as a basic ingredient of dyes, pigments, and polyester resin.
It is made from 95% naphthalene for which C-Chem possesses propriety catalyst technology that allows long life and high concentration operation.
