Useful:
  • Chemical Classes:Solvents -> Aromatic Solvents
  • Canonical SMILES:CC1=CC=C(C=C1)C
  • Inhalation Risk:A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.
  • Effects of Short Term Exposure:The substance is irritating to the eyes and skin. The substance may cause effects on the central nervous system. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
  • Effects of Long Term Exposure:The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the central nervous system. Exposure to the substance may increase noise-induced hearing loss. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
  • Description p-xylene is an aromatic hydrocarbon based on benzene with two methyl substituents with the chemical formula C8H10 or C6H4(CH3)2. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The “p” stands for para, identifying that he two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. p-Xylene is a colorless, flammable liquid practically insoluble in water. p-Xylene is a colorless watery liquid with a sweet odor and is dangerously flammable, with a flash point of 27°C. p-Xylene is widely used as a feedstock (or “building block”) to manufacture other industrial chemicals, notably terephthalic acid (TPA), purified terephthalic acid (PTA) and dimethyl-terephthalate (DMT). It also may be polymerised directly to produce parylene.
  • Physical properties Clear, colorless, watery liquid with a sweet odor. Odor threshold concentrations reported in air were 47 ppbv by Leonardos et al. (1969) and 58 ppbv by Nagata and Takeuchi (1990).
  • Uses Xylene occurs in petroleum solvents andgasoline. The widest applications of xyleneare as solvents in paints, coatings, and rubber.Xylene isomers are used in the manufacture ofdyes, drugs, pesticides, and in many organicintermediates, such as terephthalic acid andphthalic anhydride. p-Xylene is used as a precursor in the production of benzoic, isophthalic, tetraphillic acids and dimethyle esters, which are used in the manufacture of polyester. It acts as an intermediate in plastic and rubber products. As solvent; raw material for production of benzoic acid, phthalic anhydride, isophthalic and terephthalic acids as well as their dimethyl esters used in the manufacture of polyester fibers; manufacture of dyes and other organics; sterilizing catgut; with Canada balsam as oil-immersion in microscopy; clearing agent in microscope technique.
