Kambani yeduinobata pamwe neEast China University yeScience neTekinoroji, uye yekutanga inotora inoenderera kuita muketero uye Inoenderera mberi distillation maitiro ekugadziraFurfuryl doro.Zvakanyatsoona maitiro pakudziya kwakadzika uye otomatiki kure kure kushanda, zvichiita kuti mhando yacho igadzikane uye mutengo wekugadzira udzike.Isu tine yakazara chigadzirwa cheni yekukanda zvinhu, uye takafambira mberi zvikuru muhunyanzvi uye mhando dzechigadzirwa.Zvigadzirwa zvakakosha zvakaitwa kuodha zvinowanikwawo sekukumbira kubva kune vatengi.Tine zvikwata zvehunyanzvi zvinonakidzwa nemukurumbira wakanaka muindasitiri yekugadzira, kutsvagisa uye sevhisi, uyo anogona kugadzirisa matambudziko ako ekukanda nenguva.
Muna 1931, American chemist Adskins akaziva hydrogenation yefurfural kune furfuryl doro kekutanga nemhangura chromic acid secatalyst, uye akaona kuti iyo-chigadzirwa chainyanya chigadzirwa cheyakadzika hydrogenation yefurfural ring uye aldehyde boka, uye kusarudzwa kwe. chigadzirwa chinogona kuvandudzwa nekuchinja maitiro tembiricha uye catalytic reaction mamiriro.Zvinoenderana neakasiyana maitiro ekuita, maitiro efurfural hydrogenation kune furfuryl doro anogona kukamurwa kuita yemvura chikamu nzira uye gasi chikamu nzira, iyo inogona kukamurwa kuita yakanyanya kudzvanywa nzira (9.8MPa) uye yepakati kudzvinyirira nzira (5 ~ 8MPa).
mvura chikamu hydrogenation
Liquid phase hydrogenation ndeyekumisa catalyst mu furfural pa 180 ~ 210 ℃, yepakati pressure kana high pressure hydrogenation, mudziyo ishongwe isina chinhu reactor.Kuti uderedze mutoro wekupisa, chiyero chekuwedzera chefurfural chaiwanzodzorwa uye nguva yekuita (yakakura kupfuura 1h) yakawedzerwa.Nekuda kwekusanganiswa kwezvinhu, hydrogenation reaction haigone kuramba iri mudanho rekuita furfuryl doro, uye inogona kuwedzera kuburitsa zvigadzirwa zvakaita se22 methylfurfuran uye tetrahydrofurfuran doro, izvo zvinotungamira kune yakanyanya kudyiwa zvinhu, uye zvakaoma kudzoreredza tsvina inokonzeresa, nyore kuita. kukonzera kusvibiswa kwakakomba kwechromium.Uye zvakare, iyo yemvura chikamu nzira inoda kushandirwa pasi pekumanikidzwa, iyo inoda yakakwirira michina zvinodiwa.Parizvino, nzira iyi inonyanya kushandiswa munyika yedu.High reaction pressure ndiko kutadza kukuru kweiyo liquid-phase method.Nekudaro, kugadzirwa kwefurfuryl doro ne-liquid-phase reaction pasi pekudzvinyirira kwakaderera (1 ~ 1.3MPa) yakashumwa muChina, uye goho repamusoro rawanikwa.
Seimwe yezvigadzirwa zve organic synthesis, inogona kushandiswa kugadzira levulinic acid, furan resin ine zvinhu zvakasiyana-siyana, furfuryl alcohol-urea resin uye phenolic resin.Iko kutonhora kupikisa kweplasticizers yakagadzirwa kubva mairi iri nani pane iyo yeButanol uye Octanol esters.Izvo zvakare zvinonyungudutsa zvakanaka zvefuran resin, mavhanishi, uye pigment, nemafuta emaroketi.Uye zvakare, inoshandiswawo mukugadzira fibers, rabha, mishonga yekuuraya zvipembenene uye maindasitiri ekutanga.
