Codsiga
Tetrahydrofuran waxay noqon kartaa qarax marka hawada lagu qaso;waxay ku samayn kartaa peroxide qarax hawada, kaas oo gubanaya haddii uu jiro olol furan, heerkul sare iyo oksidant;Gubashada waxay soo saartaa qiiq cuncun leh.Waa iskudhis organic heterocyclic ah.Waxay ka tirsan tahay ethers waana wax soo saarka hydrogenation oo dhammaystiran ee isku dhafka udgoonka furan.Waxa loo isticmaalaa sida dareere aprotic polar dhexdhexaad ah falcelinta kiimikaad iyo soo saarista.Tetrahydrofuran qayb ahaan waa lagu khalkhaliyaa biyaha heerkulka qolka, iyo qaar ka mid ah soosaarayaasha reagent-ka ee aan xishoodka lahayn ayaa tan u isticmaala inay ka helaan faa'iido weyn iyagoo ku daraya biyaha tetrahydrofuran reagent.Tetrahydrofuran waxay si sahal ah ugu beddeshaa peroxide inta lagu jiro kaydinta.Sidaa darteed, tetrahydrofuran ganacsi ayaa inta badan laga ilaaliyaa oksaydhka BHT, 2,6-Di-tert-butyl-4-methylphenol.Tetrahydrofuran waxa lagu kaydin karaa fijaal xidhan oo leh sodium hydroxide meel mugdi ah.
Tetrahydrofuran waxay leedahay sifooyinka sunta hoose, barta karkarinta hoose iyo dheecaanka wanaagsan.Waa walxo ceeriin ah oo muhiim u ah isku dhafka organic iyo dareere aad u fiican.Waxay leedahay adeegsi aad u ballaaran.Tetrahydrofuran waxay leedahay milmayn wanaagsan walxo badan oo dabiici ah.Dhammaan xeryahooda dabiiciga ah oo aan ahayn propylene iyo fluororesin, gaar ahaan chloride polyvinyl, chloride polyvinylidene, iyo aniline, waxay leeyihiin saameyn milan oo wanaagsan, waxaana si ballaaran loo isticmaalaa dareeraha lagama maarmaanka u ah fal-celinta, taas oo loo yaqaan "qalalka caalamiga ah".
