Selelekela

Methyl propionate, e tsejoang hape e le methoxyacetate. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea methyl propionate:

 

Boleng:

- Ponahalo: Methyl propionate ke mokelikeli o pepeneneng o se nang 'mala o nang le monko o khethehileng.

- Solubility: Methyl propionate e qhibiliha haholoanyane ka har'a joala bo anhydrous le lihlapolli tsa ether, empa ha e qhibilihe ka metsing.

 

Sebelisa:

- Tšebeliso ea indasteri: Methyl propionate ke solvent ea bohlokoa ea tlhaho e sebelisoang haholo ho koahela, li-inks, li-adhesives, li-detergents le liindasteri tse ling.

 

Mokhoa:

Ho lokisoa ha methyl propionate hangata ho hlalosoa:

CH3OH + CH3COOH → CH3COOCH2CH3 + H2O

Har'a tsona, methanol le acetic acid li itšoara tlas'a ketso ea catalyst ho theha methyl propionate.

 

Lintlha tsa Tšireletseho:

- Methyl propionate ke mokelikeli o tukang 'me o lokela ho bolokoa hole le malakabe a bulehileng le mocheso o phahameng.

- Ho pepesetsoa methyl propionate ho ka baka ho teneha ha mahlo le letlalo, kahoo ho lokela ho nkoa mehato ea ho itšireletsa.

- Qoba ho hema mouoane oa methyl propionate 'me o lokela ho sebetsa sebakeng se nang le moea o motle.
