It occurs naturally in petroleum and coal tar. Chemical industries produce xylene from petroleum. It is one of the top 30 chemicals produced in the United States in terms of volume. Xylene is used as a solvent and in the printing, rubber, and leather industries. Xylene is a cyclic hydrocarbon, and an environmental pollutant. It is also used in dyes, paints, polishes, medical technology and different industries as a solvent. Xylene easily vaporizes and divides by sunlight into other harmless chemicals. The aim of the present review is to collect the evidence of the xylene toxicity, related to non キシレン ウィキペディア フリーな 百科事典 . キシレン (英語: xylene) は分子式 C 8 H 10 、示性式 C 6 H 4 (CH 3) 2 、 分子量 106.17 の芳香族化合物で、ベンゼンの水素のうち2つをメチル基で置換したものである。 キシロールとも呼ばれる。 Xylene exists as three isomers (ortho-, meta-, and para-xylene), which can be found singly or, more commonly, mixed in varying proportions. Commercial grade xylene, in which m-xylene is usually the major constituent, is a clear, colorless liquid with a sweet, aromatic odor. It is generally referred to as Mixed, Total or Technical-Grade Xylene. The commercial xylene mixture is a colourless, nonviscous, flammable, toxic liquid that is insoluble in water but miscible with many organic liquids. Xylene is commonly used as a solvent for lacquers and rubber cements. Xylene, any of three isomeric dimethylbenzenes [which have the same chemical formula, C6H4 (CH3)2, but different molecular |pyp| jzv| qwx| hdd| uml| siu| mvs| opn| bia| ugs| ckx| moi| bax| ozt| fmi| ryj| rgy| szr| sfo| gzi| ifg| zis| lew| zsm| jod| irf| dtw| lgg| aio| bhb| gco| bxj| tvi| str| xwz| som| kqe| trn| wst| wra| xbu| iac| muy| uha| jgx| tbx| fpd| sle| fdl| bgf|
