Inkampani yethuisebenzisana neYunivesiti yeSayensi neTekhnoloji yase-East China, kwaye kuqala yamkele ukusabela okuqhubekayo kwiketile kunye nenkqubo eqhubekayo yokukhutshwa kwedistillation ukwenzela ukuveliswaUtywala beFurfuryl.Ukuqonda ngokupheleleyo ukusabela kwiqondo lokushisa eliphantsi kunye nokusebenza okuzenzekelayo okude, okwenza umgangatho uzinze ngakumbi kunye neendleko zemveliso eziphantsi.Sinekhonkco lemveliso elibanzi lezinto zokuphosa, kwaye senze inkqubela phambili enkulu kubuchule kunye neentlobo zemveliso.Iimveliso ezikhethekileyo ezenziwe ukuodola zikwafumaneka ngokwesicelo sabathengi.Sinamaqela aqeqeshiweyo anandipha udumo oluhle kushishino lwemveliso, uphando kunye nenkonzo, abanokusombulula iingxaki zakho zokuphosa ngexesha.
Ngo-1931, isazi samachiza saseMelika u-Adskins waqaphela i-hydrogenation ye-furfural kwi-alcohol ye-furfuryl okokuqala ngqa nge-copper chromic acid njenge-catalyst, kwaye wafumanisa ukuba imveliso yayiyimveliso ye-hydrogenation enzulu ye-furfural ring kunye neqela le-aldehyde, kunye nokukhetha imveliso inokuphuculwa ngokutshintsha ubushushu bokusabela kunye neemeko zokusabela kwe-catalytic.Ngokweemeko ezahlukeneyo zokusabela, inkqubo ye-furfural hydrogenation ukuya kwi-furfuryl alcohol inokwahlulwa ibe yindlela yesigaba solwelo kunye nendlela yesigaba segesi, enokwahlulwa ibe yindlela yoxinzelelo oluphezulu (9.8MPa) kunye nendlela yoxinzelelo oluphakathi (5 ~ 8MPa).
inqanaba lolwelo lwe-hydrogenation
Inqanaba lolwelo lwe-hydrogenation kukunqumamisa i-catalyst kwi-furfural kwi-180 ~ 210 ℃, uxinzelelo oluphakathi okanye uxinzelelo oluphezulu lwe-hydrogenation, isixhobo yi-reactor engenanto.Ukuze kuncitshiswe umthwalo wobushushu, umlinganiselo wokongezwa kwe-furfural wawusoloko ulawulwa kwaye ixesha lokuphendula (elilikhulu kune-1h) landiswa.Ngenxa yokuxutywa kwezixhobo, i-hydrogenation reaction ayinakuhlala kwinyathelo le-furfuryl alcohol, kwaye inokuqhubeka nokuvelisa iimveliso ezifana ne-22 methylfurfuran kunye ne-tetrahydrofurfuran yotywala, ekhokelela ekusetyenzisweni okuphezulu kwezinto ezikrwada, kwaye kunzima ukubuyisela inkunkuma ye-catalyst. bangela ungcoliseko olukhulu lwechromium.Ukongezelela, indlela yesigaba solwelo kufuneka iqhutywe phantsi koxinzelelo, olufuna iimfuno eziphezulu zezixhobo.Okwangoku, le ndlela isetyenziswa kakhulu kwilizwe lethu.Uxinzelelo oluphezulu lokusabela yeyona nto isilelayo yendlela yesigaba solwelo.Nangona kunjalo, ukuveliswa kwe-alcohol ye-furfuryl ngokuphendula kwesigaba solwelo phantsi koxinzelelo oluphantsi (1 ~ 1.3MPa) kuye kwabikwa e-China, kwaye isivuno esiphezulu sifunyenwe.
Njengenye yezinto eziluhlaza kwi-organic synthesis, ingasetyenziselwa ukuvelisa i-levulinic acid, i-furan resin eneempawu ezahlukeneyo, i-furfuryl alcohol-urea resin kunye ne-phenolic resin.Ukumelana nokubanda kweeplastiki ezenziwe kuyo kungcono kune-Butanol kunye ne-Octanol esters.Ikwasisinyibilikisi esilungileyo se-furan resin, ivanishi, kunye ne-pigments, kunye namafutha e-rocket.Ukongeza, iyasetyenziswa kwimicu yokwenziwa, irabha, izibulali zinambuzane kunye namashishini asisiseko.
