Bénzéna atawa bénzén, ogé katelah C6H6, PhH jeung bénzol mangrupa sanyawa organik nu wujudna cair teu warnaan, gampang kaduruk, sarta seungit kaambeuna. Bénzéna téh karsinogén, sahingga geus teu dipaké salaku aditif pikeun béngsin. Bénzéna kaasup salah sahiji pangleyur industri penting sarta bahan baku pikeun produksi ubar, plastik, karét sintétik, jeung pewarna. Bénzéna téh aya dina minyak bumi, tapi pikeun kaperluan industri mah sok disintésis tina sanyawaan séjén nu aya dina minyak bumi.
Sajarah
[édit | édit sumber]Bénzéna kapanggih taun 1825 ku élmuwan Inggris Michael Faraday, nu ngisolasi tina gas minyak sarta dingaranan bicarburet of hydrogen. Taun 1833, kimiawan Jérman Eilhard Mitscherlich mroduksi ieu sanyawa tina distilasi asam bénzoat jeung kapur. Ku Mitscherlich ieu sanyawaan dingaranan benzin. Taun 1845, kimiawan Inggris Charles Mansfield, nu digawé ka August Wilhelm von Hofmann, ngisolasi bénzéna tina coal tar. Opat taun salajengna, Mansfield mitambeyan produksi bénzéna skala industri, dumasar kana métode coal-tar.
