  • Reactivity Profile

    1,2-Dimethylbenzene may react with oxidizing materials. .

  • Usage
    • (1) It is mainly used in the production of phthalic anhydride (2) O-xylene is the raw material for the production of germicide fenramine, tetrachlorophenyl peptide and the herbicide bensulfuron-methyl. It is used as intermediate for the manufacture of o-methyl benzoic acid. (3) It is mainly used as chemical raw materials and solvents. It can be used to produce phthalic anhydride, dyes, pesticides and drugs, such as vitamins. It can also be used as aviation gasoline additives. (4) Used as chromatographic standards and solvents (5) As raw materials of synthesis of anhydride and other organic synthesis

  • Health Hazard

    Vapors cause headache and dizziness. Liquid irritates eyes and skin. If taken into lungs, causes severe coughing, distress, and rapidly developing pulmonary edema. If ingested, causes nausea, vomiting, cramps, headache, and coma. Can be fatal. Kidney and liver damage can occur.

  • Fire Hazard

    Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back.
