PL Nazwa ksylen obejmuje wszystkie izomery ksylenu: orto-, meta- i para-. Produkt techniczny zawiera mieszaninę izomerów ksylenu oraz zwykle również etylobenzen, a jej skład jest zmienny i zależy od sposobu jej otrzymywania. W mieszaninie najwięcej jest m-ksylenu (44 ÷ 70%), natomiast p-ksylen i o-ksyl[...]
EN Xylene occurs in three isomeric forms: ortho, meta, and para. Commercial xylene is a mixture of the three isomers with m-xylene usually the principal component. There is no difference in the toxicity of the individual isomers. Liquid xylene is absorbed through intact human skin. However inhalation i[...]
