Isingeniso

I-Ethyl (S)-(-)-4-chloro-3-hydroxybutyrate iyinhlanganisela yezinto eziphilayo. Izici zayo eziyinhloko zimi kanje:

Ukubukeka: Iwuketshezi olungenambala.

Ukunyibilika: Ingancibilika kuzincibilikisi eziningi eziphilayo njenge-chloroform, i-ethanol, ne-ether.

 

Ukusetshenziswa okuyinhloko kwe-ethyl (S)-(-)-4-chloro-3-hydroxybutyrate imi kanje:

2. I-Organic synthesis: Ingasetshenziswa njenge-substrate noma i-ligand ukuze ama-chiral catalysts abambe iqhaza ekuphenduleni okuhlukahlukene kwemvelo.

Ucwaningo lwamakhemikhali: Luvame ukusetshenziswa ekuhlanganiseni, ekuhlukaniseni, nasekuhlanzweni kwezinhlanganisela ze-chiral.

 

Indlela evamile yokulungiswa kwe-ethyl (S)-(-)-4-chloro-3-hydroxybutyrate itholakala ngokusabela kwe-4-chloro-3-hydroxybutyrate nge-glycolylation.

 

Izimpahla zokuzivikela ezifanele njengezibuko zamakhemikhali, amagilavu ​​namajazi elebhu kufanele zigqokwe ngesikhathi sokusebenza.

Gwema ukuthinta isikhumba, amehlo, nolwelwesi lwamafinyila.

Qiniseka ukuthi usebenza endaweni engenawo umoya ukuze ugweme ukuhogela amagesi ayingozi.

Lapho ugcina, gwema ukuthintana nama-oxidants aqinile nama-asidi aqinile.
