Heptan yog dab tsi?
Heptane yog cov kua tsis muaj xim thiab ib qho ntawm cov khoom siv roj av. Nws yog ib tug ncaj- saw alkane nrog xya carbon thiab 16 hydrogen atoms teem nyob rau hauv ceg los yog unbranched molecules. Yog li, nws muaj cov tshuaj formula C7H16. Heptane yog cov kua dej ntawm chav tsev kub, kub heev, thiab qis boiling point. Tsis tas li ntawd, nws tsis muaj tshuaj lom thiab evaporates maj mam.
n-Heptane CAS 142-82-5 yog dab tsi?
Kuj tseem hu ua Heptane ib txwm, N-Heptane yog ib daim ntawv ntshiab ntawm Heptane thiab cov qauv tsis sib xws ntawm heptane molecule. Nws yog cov kua tsis muaj xim, flammable nrog 98.4 degrees boiling point. Nws yuav luag insoluble hauv dej tab sis me ntsis soluble hauv cawv, ether, thiab chloroform.
