Anthracene
Anthracene, feem ntau hu ua "ntsuab naphtha", yog lub nplhaib condensed aromatic hydrocarbon, CAS naj npawb 120-12-7, molecular mis C14H10, molecular hnyav 178.22. Tsis muaj xim prismatic crystals nrog xiav-violet fluorescence, sublimability, thiab toxicity. Insoluble hauv dej, me ntsis soluble hauv ethanol, soluble hauv ether, benzene, toluene, chloroform, acetone thiab carbon tetrachloride. Anthracene chav tsim dimers nyob rau hauv qhov kev txiav txim ntawm platinum thiab 700 ~ 800 degree. Nyob rau hauv European Union "Kev Sau Npe, Kev Ntsuas, Kev Tso Cai thiab Kev Txwv Cov Tshuaj Siv Tshuaj" (REACH), anthracene tau raug teev tias yog cov khoom muaj kev txhawj xeeb heev (SVHC).
