Selelekela

Propyl acetate (eo hape e tsejoang e le ethyl propionate) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea propyl acetate:

 

Boleng:

- Ponahalo: Propyl acetate ke mokelikeli o se nang 'mala o nang le monko o kang oa litholoana.

- Solubility: Propyl acetate e qhibiliha ka har'a lino tse tahang, li-ethers le lihlapolli tse mafura, 'me e batla e sa qhibilihe ka metsing.

 

Sebelisa:

- Tšebeliso ea indasteri: Propyl acetate e ka sebelisoa e le solvent 'me e atisa ho sebelisoa ha ho etsoa litlolo, li-varnish, li-adhesives, fiberglass, resin le polasetiki.
