Para Nitro Toulene Ortho Sulphonic acid popularly known as PNTOSA is an organic compound. PNTOSA has a byproduct known as sulphuric acid. The chemical name of the compound is 4 Nitro Toluene 2 Sulfonic Acid or 1 Methil 4 Nitro Benzene 2 Sulphonic Acid.
Here are some important properties associated with PNTOSA:
• Its appearance is like a crystal having brown or grey color.
• PNTOSA’s empirical formula is C 7 H7NO5S
• It is mostly used for dying some stuff.
• It is highly combustible and therefore must not be kept near fire or at high temperature.
• Para Nitro Toluene(PNT) and Oleum are the raw materials used for its manufacturing.
PNT + Oleum = PNTOSA + Dilute sulfuric acid
