Khoom Description
P-Xylene CAS 106-42-3 yog dab tsi?
P-Xylene (CAS 106-42-3) yog xim tsis muaj xim- cov kua pob tshab muaj peev xwm ua kom crystallizing ntawm qhov kub thiab txias, nrog cov ntxhiab tsw zoo ib yam li toluene. Nws muaj ib tug molecular mis C₈H₁₀, molecular hnyav 106.17, thiab aliases xws li 1,4-Dimethylbenzene, teej tug mus rau peb xylene isomers.P-Xylene exhibits lub melting point ntawm 13.3 degree, boiling point ntawm 138.4℃ntawm 10 g. ), me ntsis sib dua li dej. Nws yog insoluble hauv dej (0.52 g / L) tab sis miscible nrog cov kuab tshuaj organic xws li ethanol, diethyl ether, acetone, thiab benzene. Nws saturated vapor siab yog 1.16 kPa (25 degree), thiab flash point yog 25℃(kaw-khob).
