p xylene density (CAS 106-42-3)
The density of p-xylene at 20°C is approximately 0.86 g/cm³ (or 0.861 g/mL).
P-Xylene Properties
P-xylene (PX) is a vital organic chemical feedstock with the molecular formula C8H10. It is primarily used to produce terephthalic acid (PTA) or dimethyl terephthalate (DMT). PTA or DMT can then react with ethylene glycol to form polyethylene terephthalate (PET), commonly known as polyester. The primary feedstock for paraxylene is mixed xylene (MX), which consists of paraxylene, ortho-xylene, and meta-xylene.
