Selelekela

Isobutyrate ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea isobutyrate:

 

Boleng:

Ponahalo: Isobutyl butyrate ke mokelikeli o bonaletsang o se nang 'mala o nang le monko o khethehileng.

Boima: hoo e ka bang 0.87 g/cm3.

Sollubility: Isobutyrate e ka qhibiliha ka har'a metsoako e mengata ea tlhaho e kang ethanol, ethers le benzene solvents.

 

Sebelisa:

Lisebelisoa tsa temo: Isobutyl butyrate e boetse e sebelisoa e le taolo ea kholo ea limela ho khothaletsa kholo ea limela le ho butsoa ha litholoana.

 

Mokhoa:

Isobutyl butyrate e ka fumanoa ka ho arabela isobutanol ka butyric acid. Hangata karabelo e etsoa ka pel'a li-catalysts tsa asiti, 'me li-catalysts tse sebelisoang hangata ke sulfuric acid, aluminium chloride, joalo-joalo.
