Definition of xylene in English: xylenenoun ˈzʌɪliːnˈzaɪlin mass nounChemistry A volatile liquid hydrocarbon obtained by distilling wood, coal tar, or petroleum, used in fuels and solvents and in chemical synthesis. 〔化〕二甲苯 Alternative name: dimethylbenzene; chemical formula: C₆H₄(CH₃)₂; three isomers Example sentencesExamples - It was unpromising stuff, but Hofmann and others had discovered that by distillation one could separate from it several carbon-rich, odorous organic compounds such as benzene, toluene, xylene, and phenol.
- Fuels such as petroleum are mixtures of various hydrocarbons, and may contain benzene, toluene, xylene, and styrene, and other components.
- If you do insist on using solvents, avoid low-flash point solvents like gasoline, xylene, lacquer thinner, etc. which are dangerously flammable.
- But many other chemicals linked to reproductive health problems, including xylene, trichloroethylene, phenols, and acetone, remain in use.
- But since the early 1920s, the oil companies have been blocking ethanol use - while using toxic substance like lead, benzene, toluene and xylene.
- Petroleum fuels contain several toxic compounds, including benzene, toluene and xylene - all considered carcinogens.
OriginMid 19th century: from xylo- 'of wood' + -ene. xylophone from mid 19th century: This is the only common word formed from Greek xylo- ‘wood’, although it is common enough in science in words such as xylene (mid 19th century) a hydrocarbon made from distilled wood, and archaeologists can describe a single lump of wood as monoxylic (mid 19th century) on the model of monolithic (mid 19th century) for ‘single stone’.
