Phthalic anhydride is a white solid obtained from partial oxidation with air of o-xylene on a solid bed. It is used in solid form in FIBCs of 500 kg or in molten form.

Maleic anhydride is a solid at room temperature, which is obtained from the partial oxidation (solid-bed) of n-butane with air. The main industrial application of maleic anhydride is glycol polymerization and unsaturated epoxides linear with polyesters. It is sold in liquid form, in trucks at a temperature no lower than 52ºC.

Cyclohexane is a naphthene produced by benzene hydrogenation. Its main use is the synthesis of cyclohexanol/cyclohexanone for the production of the caprolactam and adipic acid, precursors to nylon.
