Intshayelelo
(5h) i-furanone i-organic compound kunye ne-chemical formula C8H12O3 kunye ne-molecular weight ye-156.18g / mol. Lulwelo olungenambala ukuya kumthubi oluluthuthu kunye nobumnandi obukhethekileyo beswekile. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: Ayinambala ukuya kulwelo olutyheli olukhanyayo
-Indawo yokunyibilika:-7 ℃
Indawo yokuBilisa: 171-173 ℃
-Ubuninzi: malunga. 1.079g/cm³
-I-Solubility: Inokunyibilika emanzini, i-ethanol kunye ne-Ether solvents
-Uzinzo: uzinzile kwiqondo lokushisa
Sebenzisa:
-Isongezo sokutya: Ngenxa yobumnandi bayo obukhethekileyo, isetyenziswa njenge-agent yokunambitha ukutya, ngakumbi kwi-candy, jam kunye nedessert.
-Iziqholo: Ingasetyenziswa njenge-condiment ukunika ukutya incasa eyodwa.
-Ishishini leperfume: njengenye yezithako ze-perfume essence.
Indlela:
(5h) ifuranone inokulungiswa ngala manyathelo alandelayo:
1. Nge-3-methyl -2-pentanone njengento yokuqala, i-3-hydroxy -4-methyl -2-pentanone yafunyanwa yi-keto-alcohol reaction.
I-2.3-hydroxy -4-methyl -2-pentanone iphendulwa kunye ne-etherifying agent (efana ne-diethyl ether) ukuvelisa imveliso ye-etherification.
3. Imveliso ye-etherification iphantsi kwe-acid catalysis kunye ne-deoxidation reaction to find furanone (5h).
Ulwazi ngoKhuseleko:
-(5h) i-furanone ithathwa njengekhuselekile ukusetyenziswa ngokubanzi, kodwa inokucaphukisa ulusu kunye namehlo kwiindawo eziphezulu.
-Ukusetyenziswa kufuneka kuhlawule ingqalelo kumanyathelo okukhusela, ugweme ukudibanisa nesikhumba kunye namehlo, kwaye ugcine indawo yokusebenza enomoya.
-Landela iinkqubo ezifanelekileyo zokhuseleko xa uyisebenzisa, kwaye uyigcine kwindawo eyomileyo, epholileyo, kude nomlilo kunye ne-oxidizing agents.
