Kuyini i-2(5H)-Furanone CAS 497-23-4?

2 (5H) - I-Furanone iyi-lactone enezakhiwo ezijwayelekile ze-ester, njengokunciphisa kanye ne-ammonolysis; Iqukethe ama-double bond ahlanganiswe nama-ester, ukusabela kokwengeza kukaMichael kungenzeka; Ngenxa yokuxhumana kwayo nomoya-mpilo kanye nomphumela wokuhoxiswa kwama-electron amaqembu e-ester adluliselwa ngama-double bond, iqembu layo le-methylene line-acidity futhi lingancishwa i-hydrogen yizisekelo eziqinile.

Isicelo

2 (5H) - I-Furanone iyinhlanganisela ye-organic heterocyclic, i-butenolide elula kakhulu, ebonakala njengoketshezi olungenambala ekamelweni lokushisa. Ifomula yayo yesakhiwo yi-γ - i-crotonyl lactone, okuyizinto ezandulela ama-molecule amaningi asebenzayo emithini. Isakhiwo sayo sivame ukutholakala kuma-molecule asebenzayo njengemithi yokulwa namagciwane, imithi yokulwa namagciwane, imithi yokulwa nomdlavuza, kanye nemithi yokulwa namagciwane.
