Downstream Products Made from o-Xylene (ortho-xylene) CAS 95-47-6
Downstream Products and Derivatives:
- Phthalic Anhydride: The primary derivative (accounting for over 70% of o-xylene consumption) used in manufacturing plasticizers (flexible PVC), alkyd resins, polyester resins, and dyes.
- Plasticizers: Produced via phthalic anhydride to make PVC flexible.
- Solvents/Thinners: Directly used as a solvent in paints, varnishes, enamels, and rubber cements.
- Chemical Intermediates: Used to produce phthalonitrile, xylenol, and xylidine.
- Agrochemicals/Pesticides: Employed in germicides and herbicides such as bensulfuron-methyl.
- Pharmaceuticals: Utilized in synthesizing certain vitamins and drugs.
- Aviation Gasoline: Added as an octane-boosting additive.
- Other Derivatives: Chlorinated compounds (2-chloro-o-xylene and 4-chloro-o-xylene).
