Ubuhanga bwo gukora inzoga za Furfuryl

Isosiyete yacuikorana na kaminuza yubumenyi n’ikoranabuhanga mu Bushinwa bwo mu Burasirazuba, ikanabanza gufata ingamba zihoraho mu isafuriya no Gukomeza gusibanganya umusaruro.Inzoga ya Furfuryl. Yatahuye neza reaction ku bushyuhe buke no gukora byikora byikora, bigatuma ubuziranenge buhinduka kandi igiciro cyumusaruro kiri hasi. Dufite urunigi rwuzuye rwibicuruzwa, kandi twateye imbere cyane mubuhanga nubwoko butandukanye. Ibicuruzwa bidasanzwe bikozwe gutumiza nabyo birahari nkuko bisabwa nabakiriya. Dufite amakipe yabigize umwuga afite izina ryiza mubikorwa byo gukora, ubushakashatsi na serivisi, bashobora gukemura ibibazo bya casting mugihe gikwiye.

Mu 1931, umuhanga mu by'imiti w’umunyamerika Adskins yatahuye hydrogène y’inzoga ya furfuryl ku nshuro ya mbere hamwe na aside chromic acide y'umuringa nka catalizator, maze asanga ibicuruzwa biva mu bicuruzwa ahanini biva mu mazi ya hydrogenation y’impeta ya furfuran na aldehyde, hamwe no guhitamo kwa igicuruzwa gishobora kunozwa muguhindura ubushyuhe bwa reaction na catalitiki yimiterere. Ukurikije uburyo butandukanye bwo kubyitwaramo, inzira ya hydrogenation ya furfural kuri alcool ya furfuryl irashobora kugabanywa muburyo bwa feri ya feri nuburyo bwa gaz gaz, bishobora kugabanywa muburyo bwumuvuduko mwinshi (9.8MPa) nuburyo bwumuvuduko ukabije (5 ~ 8MPa).

icyiciro cya hydrogenation

Amazi ya hydrogenation yo guhagarika ni uguhagarika catalizator muri furfural kuri 180 ~ 210 ℃, umuvuduko wo hagati cyangwa hydrogenation yumuvuduko mwinshi, igikoresho ni reaction yumunara wubusa. Kugirango ugabanye ubushyuhe, ubushyuhe bwiyongera bwa furfural bwakunze kugenzurwa kandi igihe cyo kubyitwaramo (kirenze 1h) cyongerewe igihe. Bitewe no gusubiza inyuma ibikoresho, reaction ya hydrogenation ntishobora kuguma mu ntambwe yo kubyara inzoga ya furfuryl, kandi irashobora gukomeza kubyara umusaruro nka 22 methylfurfuran na tetrahydrofurfuran inzoga, biganisha ku gukoresha ibikoresho byinshi bibisi, kandi bigoye kugarura imyanda, byoroshye bitera umwanda ukomeye wa chromium. Byongeye kandi, uburyo bwicyiciro cyamazi bugomba gukoreshwa mubitutu, bisaba ibikoresho bisabwa cyane. Kugeza ubu, ubu buryo bukoreshwa cyane cyane mu gihugu cyacu. Umuvuduko ukabije wibisubizo ningenzi muburyo bwuburyo bwamazi. Nyamara, mu Bushinwa havuzwe umusaruro wa alcool furfuryl ukoresheje feri-fonction reaction yumuvuduko muke (1 ~ 1.3MPa), kandi habonetse umusaruro mwinshi.

Nka kimwe mu bikoresho fatizo bya synthesis organique, irashobora gukoreshwa mukubyara aside ya levulinic, resin resin ifite ibintu bitandukanye, furfuryl alcool-urea resin na fenolike. Kurwanya ubukonje bwa plasitiki ikozwe muri yo nibyiza kuruta ibya estan ya Butanol na Octanol. Nibyiza kandi kumashanyarazi ya furan resin, langi, na pigment, hamwe na lisansi ya roketi. Byongeye kandi, ikoreshwa kandi muri fibre synthique, reberi, imiti yica udukoko ninganda zikora inganda.
