Selelekela

Bifenpentanone, eo hape e tsejoang e le diphenopylacetone, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea bifenpentanone:

 

Boleng:

- Ponahalo: Bifenpentone ke kristale e se nang 'mala kapa e mosehla.

- Sollubility: E qhibiliha ka har'a metsoako e mengata ea tlhaho, joalo ka joala le ethers, 'me e qhibiliha hanyane ka metsing.

- Lik'hemik'hale tsa lik'hemik'hale: Bifenpentone e na le matla a ho fokotsa matla, 'me e le motsoako o sebetsang, o ka kenya letsoho liketsong tse sa tšoaneng tsa lik'hemik'hale.
