Diphenylmethanol , (C6H5)2CHOH (tseem hu ua benzhydrol tshuaj ), yog ib qho cawv thib ob nrog qhov sib txheeb molecular hnyav ntawm 184.23 g / mol. Nws muaj ib melting point ntawm 69 ° C thiab a kub point ntawm 298 ° C. Nws tau siv hauv tshuaj tsw qab thiab kev tsim tshuaj.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov ntaub ntawv melting point ntawm Diphenylmethanol?
Diphenylmethanol
| Cov npe | |
|---|---|
| Qhov tshwm sim | Dawb siv lead ua |
| Qhov ntom | 1.103 g / cm3 |
| Melting point | 69 ° C (156 ° F; 342 K) |
| Boiling point | 298 ° C (568 ° F; 571 K) |
Tom qab ntawd, lo lus nug yog, koj ua li cas xam qhov theoretical yield ntawm Diphenylmethanol?
- siv cov kev suav Grams = Moles x Molar mass, peb tau txais cov lus nram qab no:
- Theoretical tawm los ntawm diphenylmethanol = moles ntawm benzophenone x molar loj ntawm.
- Diphenylmethanol yog dab tsi? Theoretical yield = 0.012 moles x 184.238 g mol.
- ? theoretical.
- 5) Xam qhov feem pua ntawm cov tshuaj tiv thaiv.
Kuj nug, yog Diphenylmethanol soluble hauv dej?
benzhydrol tshuaj . (C6H5)2CHOH koob tsis muaj xim; melting point 69 ° C; me ntsis soluble nyob rau hauv dej , heev soluble hauv ethanol thiab ether; siv rau hauv kev npaj ntawm lwm cov organic tebchaw nrog rau cov tshuaj antihistamines.
Benzil puas yog ketone?
Benzil . Nqe lus piav qhia: Benzil yog ib qho alpha-diketone uas yog ethane-1, 2-dione hloov los ntawm phenyl pawg ntawm txoj haujlwm 1 thiab 2 raws li. Nws yog alpha-diketone thiab muaj ntxhiab tsw ketone lub cev.
