<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Isethulo: Ngaleso sikhathi, kwakwakhiwa i-formic acid ngokuncibilikisa izintuthwane ezifile, futhi izidumbu zezintuthwane zikaDöbereiner cishe zaziqukethe izinto ezithile zezitshalo. Ngo-1840, usokhemisi waseScotland uJohn Stenhouse wathola ukuthi ikhemikhali elifanayo lingakhiqizwa ngokuhluza izinhlobo eziningi zezitshalo, kuhlanganise nommbila, i-oats, i-bran, ne-sawdust, nge-aqueous sulfuric acid; futhi wanquma ifomula yokuhlola ye- C5H4O2. Ngo - 1845 uGeorge Fownes wabiza la mafutha ngokuthi i - furfurol kusuka kwelithi furfur - bran, nelithi oleum. Leli gama lahlala liphawuleka ezincwadini kwaze kwaba ngo-1901 lapho usokhemisi waseJalimane uCarl Harries ethola ukwakheka kwe-furfural. I-furfural yahlala ingaziwa kuze kube ngu-1922, lapho i-Quaker Oats Company iqala ukuyikhiqiza ngobuningi kusuka eziqwini ze-oat. Namuhla, i-furfural isakhiqizwa ngemikhiqizo eseceleni yezolimo efana ne-sugarcane bagasse nama-corn cobs. Amazwe amakhulu akhiqiza i-furfural namuhla yiDominican Republic, iNingizimu Afrika neChina. Umbuzo: Iyiphi ingxenye yommbila esetshenziswayo namuhla ekukhiqizeni i-furfural?  <response>: izikhwebu zommbila
