Intshayelelo
I-γ-crotonyllactone (GBL) i-organic compound. Oku kulandelayo sisingeniso kubume, ukusetyenziswa, indlela yokuvelisa kunye nolwazi lokhuseleko lwe-GBL:
Umgangatho:
Imbonakalo: Ulwelo olungenambala olucacileyo olunevumba le-ethanol.
Ubuninzi: 1.125 g/cm³
Ukunyibilika: Inyibilika kwizinyibilikisi ezininzi zezinto eziphilayo, ezifana namanzi, utywala, iether, njl.
Sebenzisa:
Ukusetyenziswa kwamashishini: I-GBL isetyenziswa ngokubanzi njenge-surfactant, i-solvent yedayi, i-solvent ye-resin, i-solvent yeplastiki, i-agent yokucoca, njl.
Indlela:
I-GBL inokufumaneka nge-oxidizing crotonone (1,4-butanol). Indlela ekhethekileyo yokulungisa i-crotonone kunye negesi ye-chlorine ukuvelisa i-1,4-butanedione, kwaye emva koko i-hydrogenate 1,4-butanedione kunye ne-NaOH ukuvelisa i-GBL.
Ulwazi ngoKhuseleko:
I-GBL ineempawu zokuguquguquka okuphezulu kunye nokufunxa lula kwesikhumba kunye ne-mucous membranes, kwaye inetyhefu ethile emzimbeni womntu. Sebenzisa ngononophelo.
I-GBL inokuba nefuthe kwinkqubo ye-nervous central, kwaye idosi egqithisileyo inokukhokelela kwimiphumo emibi efana nesiyezi, ukozela, kunye nobuthathaka bemisipha. Ukuthobela imithetho nemigaqo efanelekileyo.
