Ucwaningo ngenqubo yokukhiqiza i-furfuryl alcohol nge-hydrogenation reaction of furfural

Ukuqapha ku-inthanethi kunikeza ngokushesha imiphumela yezinga lokuguqulwa, kufinyeze umjikelezo wocwaningo nentuthuko izikhathi ezi-3 uma kuqhathaniswa nokuqapha elabhorethri ungaxhunyiwe ku-inthanethi.

I-Furfuryl alcohol yiyona nto eyinhloko yokukhiqiza i-furan resin, futhi ingasetshenziswa njenge-antiseptic resin kanye nezinto zokusetshenziswa kwemithi.I-Hydrogenation ingakhiqiza i-tetrahydrofurfuryl alcohol, okuyi-solvent enhle yama-varnishes, ama-pigments kanye nophethiloli we-rocket.I-Furfuryl alcohol ingalungiswa nge-hydrogenation of furfural, okungukuthi i-furfural i-hydrogenated futhi yehliselwe ku-furfuryl alcohol ngaphansi kwezimo ze-catalyst.

Phakathi nenqubo yocwaningo lwalokhu kusabela, kuyadingeka ukuthola ngobuningi izinto zokusetshenziswa nemikhiqizo, futhi uhlole izinga lokuguqulwa ukuze uhlole inqubo yokusabela elungile futhi uhlole umthelela wezinga lokugeleza, izinga lokushisa, kanye nengcindezi kunqubo yokusabela.Indlela yocwaningo yendabuko iwukuthatha amasampula bese uwathumela elabhorethri ngemva kokusabela, bese usebenzisa izindlela zechromatographic zokuhlaziya ubuningi.Ukusabela ngokwako kuthatha imizuzu emi-5-10 kuphela ukuqeda, kodwa ukusampula nokuhlaziya okulandelayo kudinga okungenani imizuzu engu-20, okudla isikhathi kakhulu futhi kudingeka imizamo yomzimba.

Enqubweni yokuthuthukisa, ubuchwepheshe be-spectroscopy eku-inthanethi bungabuka ukuthambekela okushintshayo kwezinto ezingavuthiwe nemikhiqizo ngesikhathi sangempela, futhi bunikeze okuqukethwe kwezinto zokusetshenziswa nemikhiqizo.Izindawo eziphakeme zeziqongo zesici ezimakwe esithombeni esingenhla zibonisa okuqukethwe kwezinto ezingavuthiwe noma imikhiqizo.Isibalo esingezansi sibonisa isilinganiso somkhiqizo nokuqukethwe kwempahla eluhlaza okuhlaziywa ngobuhlakani isofthiwe.Izinga lokuguqulwa kwezinto ezingavuthiwe liphezulu kakhulu ngaphansi kwezimo ezi-2 zenqubo.Ubuchwepheshe bokuqapha ku-inthanethi busiza abacwaningi ukuthi banqume ukuthi lesi simo siyisimo esihle kakhulu senqubo.Uma kuqhathaniswa nezindlela zokuhlola ilabhorethri ye-chromatographic, ukuqapha ku-inthanethi konga amasampula angaxhunyiwe ku-inthanethi nesikhathi sokuhlola ilabhorethri, kufinyeza umjikelezo wocwaningo nentuthuko izikhathi ezingaphezu kwezintathu, futhi kusindisa kakhulu isikhathi nezindleko zocwaningo nentuthuko yenqubo yebhizinisi.
