Isicelo
I-Sucrose isetshenziswa kakhulu ekudleni, kwizimonyo nakwezokwelapha, futhi isetshenziswa njengezinga lokuhlaziya nokutholwa.Ingasetshenziselwa ukulungisa i-citric acid, i-caramel, i-invert sugar, insipho esobala, njll. Ingavimbela ukukhula kwamagciwane ekugxiliseni okuphezulu, futhi ingasetshenziswa njenge-excipient yethebhulethi ye-preservative kanye ne-antioxidant kwezokwelapha.I-reagent sucrose isetshenziselwa ukunqunywa kwe-1-naphthol, ukuhlukaniswa kwe-calcium ne-magnesium kanye nokulungiswa kwesiko lezinto eziphilayo.
I-Sucrose, ingxenye eyinhloko kashukela wetafula, iwuhlobo lwe-disaccharide, equkethe i-molecule yeqembu le-hemiacetal hydroxyl ye-glucose kanye ne-molecule yeqembu le-hemiacetal hydroxyl le-fructose elijikijelwe omunye nomunye futhi liphelelwe amanzi.I-Sucrose imnandi, ayinaphunga, iyancibilika emanzini ne-glycerol, futhi inyibilika kancane otshwaleni.I-spinogenic, kodwa ayinawo umphumela we-photochromic.I-Sucrose cishe itholakala emhlabeni wonke emaqabunga, izimbali, iziqu, imbewu nezithelo zombuso wezitshalo.Igcwele kakhulu umoba, isithombo sebhitrudi kanye nencindi ye-maple.I-Sucrose inokunambitheka okumnandi futhi iwukudla okubalulekile nesinongo esimnandi.Ihlukaniswe ngoshukela omhlophe, ushukela onsundu, ushukela we-rock, ushukela we-rock, noshukela ogqamile (ushukela ophuzi)
Izici ezingokomzimba
I-Sucrose inyibilika kakhulu emanzini, futhi ukuncibilika kwayo kuyanda ngokwanda kwezinga lokushisa, futhi ayiwuhambisi ugesi lapho incibilika emanzini.I-Sucrose nayo iyancibilika ku-aniline, azobenzene, ethyl acetate, amyl acetate, phenol encibilikisiwe, i-ammonia ewuketshezi, ingxube yotshwala namanzi kanye nengxube ye-acetone namanzi, kodwa ayincibiliki kumakhemikhali aphilayo njengophethiloli, i-petroleum, utshwala obungenayo i-anhydrous, i-trichloromethane. , i-carbon tetrachloride, i-carbon disulfide ne-turpentine.I-Sucrose yinto e-crystalline.Amandla adonsela phansi athile amakristalu e-sucrose amsulwa ngu-1.5879, futhi amandla adonsela phansi athile esixazululo se-sucrose ayahluka kuye ngokugxila kanye nezinga lokushisa.Ukujikeleza okuqondile kwe-sucrose kungu-+66.3 ° kuya ku-+67.0 °.
Izakhiwo zamakhemikhali
Izixazululo ze-Sucrose ne-sucrose ngaphansi kwesenzo sokushisa, i-asidi, i-alkali, imvubelo, njll., zikhiqiza ukusabela okuhlukahlukene kwamakhemikhali.Ukusabela akuphumeleli kuphela ekulahlekelweni okuqondile kwe-sucrose, kodwa nasekukhiqizeni izinto eziyingozi ekukhiqizeni ushukela.
Uma i-sucrose ecwebezelayo ishisiswe ibe ngu-160°C, izobola ngokushisa futhi inyibilike ibe uketshezi oluwugqinsi nolubonisa ngale, bese iphinda ikhanye uma isipholile.Isikhathi sokushisa siyandiswa, i-sucrose ibola ibe yi-glucose ne-defructose.Ekushiseni okuphezulu kwe-190-220 ° C, i-sucrose izophelelwa amanzi futhi ihlanganiswe ibe yi-caramel.Ukushisa okwengeziwe kwe-caramel kukhiqiza i-carbon dioxide, i-carbon monoxide, i-acetic acid ne-acetone.Ngaphansi kwezimo ezinomswakama, i-sucrose ibola ku-100 ° C, ikhulula amanzi futhi ibe mnyama umbala.Lapho isixazululo se-sucrose sishisiswa ukuze sibilise ukucindezela komkhathi isikhathi eside, i-sucrose encibilikisiwe ibola kancane ibe amanani alinganayo e-glucose ne-fructose, okungukuthi, ukuguqulwa kwenzeka.Uma isixazululo se-sucrose sishisiswe ngaphezu kwe-108 ℃, sizokhishwa nge-hydrolyzed ngokushesha, futhi lapho ukugcwala kwesisombululo sikashukela, umphumela we-hydrolysis ubaluleke kakhulu.Izinto zensimbi ezisetshenziswa emkhunjini obilayo nazo zinomthelela kuzinga lokuguqulwa kwe-sucrose.Isibonelo, ukuguqulwa kwesisombululo se-sucrose ezitsheni zethusi kukhulu kakhulu kunezitsha zesiliva, futhi izitsha zengilazi zinomthelela omncane.
