Mexico's petrochemical specialist Pemex Petroquímica operates as a subsidiary of state-owned oil and gas company Petróleos Mexicanos (PEMEX). It produces non-basic petrochemicals resulting from the transformation of PEMEX natural gas, methane, ethane, propane and naphtha. The company, which owns and operates eight plants in northern and southern Mexico, manufactures, sells and distributes ethanol, ammonia, benzene, ethylene, ethylene oxide, glycol, orthoxylene, paraxylene, propylene, toluene, xylene, acetonitrile, cyanhydric acid, acrylonitrile, high and low density polyethylene, methanol, and vinyl chloride. The company was founded in 1992 and is based in Coatzacoalcos, Mexico. As a consequence of Pemex's corporate restructuring brought about by Mexico's energy reforms, its former units Pemex Petroquímica, Pemex Gas y Petroquímica Básica, and Pemex Refinación, will be incorporated to a new subsidiary called Pemex Transformación Industrial.
