Isaziso Sokusungula Sakamuva
I-Gamma-Valerolactonenoma i-γ-Valerolactone
Isifinyezo sithiGVL
Sikhiqize inqwaba entsha engu-2000 kg esitokweni. Ingathunyelwa ngokushesha ngemuva kokuthola i-oda.
Ikhwalithi ephezulu kanye nentengo engcono kakhulu, Noma yini edinga ukuthi sikusize, wamukelekile ukuxhumana nathi nganoma yisiphi isikhathi.
Ukuze uthole ulwazi oluningiliziwe njengoba kulandelwe isithenjwa sakho.

三, Isicelo
I-1.gamma-Valerolactone inekhono eliqinile lokusabela, futhi ingasetshenziswa njengesincibilikisi kanye nezinhlobonhlobo zamakhemikhali ahlobene.
I-2.gamma-Valerolactone isetshenziswa njenge-lubricant, i-plasticizer, i-gelling agent yama-nonionic surfactants, isigaba se-lactone se-additive petroli eholayo.
I-3.gamma-Valerolactone iphinde isetshenziselwe ukudaya i-cellulose ester kanye ne-synthetic fiber dyeing.
四. Isitoreji
1. Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo nemithombo yokushisa.
3. Gwema ukukhanya kwelanga okuqondile.
4. Gcina isitsha sivalwe ngokuqinile.
5. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-ejenti anciphisayo, nama-acids, futhi igweme ukugcinwa okuxubile.
6. Ifakwe izinhlobo ezihambisanayo namanani ezinto zokucisha umlilo.
7. Indawo yokugcina kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.
