m-Xylene (meta-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The m- stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and p-xylene. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flammable.

  • ميتا-زيلين هو هيدروكربون عطري وهو واحد من المتزامرات الثلاثة من ثنائي ميثيل البنزين المعروفة بشكل جماعي باسم زيلين. تشير السابقة ميتا إلى أن مجموعتي الميثيل في الزيلين تحتل الموضعين 1 و 3 على حلقة البنزين. ويختلف عن المتزامرات الأخرى، o-زيلين و p-زيلين. ومع ذلك فإن كل لها نفس الصيغة الكيميائية C6H4 (CH3) 2. وجميع متزامرات زيلين عديمة اللون وقابلة للاشتعال للغاية.

  • Il m-xilene (leggi: meta-xilene) è un idrocarburo aromatico; la sua struttura è quella di un benzene in cui due atomi di idrogeno nelle posizioni 1 e 3 sono stati sostituiti da due gruppi metile. A temperatura ambiente si presenta come liquido incolore, volatile e infiammabile. È un isomero dell'o-xilene e del p-xilene. Si ottiene generalmente come sottoprodotto della sintesi del p-xilene, isolandolo per distillazione dalla miscela dei tre xileni. Il m-xilene viene convertito in acido isoftalico per ossidazione catalitica. Trova impiego anche nella produzione della e della .
  • m-Ksylen – organiczny związek chemiczny, węglowodór aromatyczny, jeden z trzech izomerycznych ksylenów. Jest to pochodna benzenu zawierająca dwie grupy metylowe przyłączone do pierścienia w położeniu meta (1,3). Inne izomery ksylenu to o-ksylen i p-ksylen. m-Ksylen rozpuszcza się w niepolarnych rozpuszczalnikach jak np. w węglowodorach aromatycznych, podobnie jak wszystkie ksyleny.
