Selelekela

γ-crotonyllactone (GBL) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa mofuta, tšebeliso, mokhoa oa tlhahiso le tlhaiso-leseling ea polokeho ea GBL:

 

Boleng:

Ponahalo: Mokelikeli o bonaletsang o se nang 'mala o monko o kang oa ethanol.

Boima: 1.125 g/cm³

Solubility: E qhibiliha ka har'a lihlapolli tse ngata tsa tlhaho, joalo ka metsi, joala, ether, joalo-joalo.

 

Sebelisa:

Tšebeliso ea indasteri: GBL e sebelisoa haholo joalo ka surfactant, dae solvent, resin solvent, polasetiki ea polasetiki, sesebelisoa sa ho hloekisa, joalo-joalo.

 

Mokhoa:

GBL e ka fumanoa ka oxidizing crotonone (1,4-butanol). Mokhoa o khethehileng oa ho itokisa ke ho itšoara ka crotonone ka khase ea chlorine ho hlahisa 1,4-butanedione, ebe joale hydrogenate 1,4-butanedione e nang le NaOH ho hlahisa GBL.
