Styren: Vlastnosti, Toxicita & Použití
Styren (fenylethen, vinylbenzen) je aromatická průmyslová chemikálie. Patří k přírodním produktům . Jako bezbarvou čirou kapalinu s charakteristickým zápachem jej poprvé izoloval berlínský lékárník Johann Eduard Simon v roce 1839 z pryskyřice stromu Liquidambar orientalis. Nejnovější výzkumy dokládají použití styrenu při mumifikaci mrtvých již ve starém…
