Cov cov qauv ua piv txwv ntawm cyclohexane hmoov yog CH2 thiab nws qhov hnyav molecular yog 84.16 amu.

Hais txog qhov no, dab tsi yog cov qauv siv rau c6h12?

C6H6 C6H12 HCO3 C2H6 C 2H40 40. Xaiv cov khub sib txuas nrog tib yam empirical formula.

Tsis tas li, dab tsi yog cyclohexane soluble hauv? Cyclohexane yog xim tsis muaj xim, mobile kua nrog ib tug me me, qab zib tsw. Nws yog me ntsis soluble hauv dej thiab soluble hauv cawv, acetone, benzene, ethanol, ethyl ether, txiv roj roj, thiab carbon tetrachloride. Melting Point: 6.47 ° C.

Ib yam li ntawd, koj yuav pom tus qauv ua piv txwv li cas?

Pib nrog tus naj npawb ntawm grams ntawm txhua lub caij, muab rau hauv qhov teeb meem. Hloov qhov hnyav ntawm txhua lub hauv paus rau moles siv cov molar loj los ntawm cov lus teev tseg. Faib txhua tus nqi mole los ntawm tus lej tsawg tshaj plaws ntawm moles suav.

Yuav ua li cas yog cyclohexane tsim?

Kev tsim khoom niaj hnub. Nyob rau hauv industrial scale, cyclohexane hmoov yog tsim los ntawm hydrogenation ntawm benzene thaum muaj Raney nickel catalyst. Cov neeg tsim khoom ntawm cyclohexane hmoov suav txog kwv yees li 11.4% ntawm kev thov thoob ntiaj teb rau benzene. Cov tshuaj tiv thaiv yog exothermic heev, nrog ΔH (500 K) = -216.37 kJ / mol).
