Isticmaalka
Mid ka mid ah astaamaha muhiimka ah ee THF waa isku-duubnaanteeda sida dareeraha.Dareerahan aan midabka lahayn, ee saafiga ah ayaa ku milma walxo kala duwan, oo ay ku jiraan biyaha, ethanol, ether, acetone, iyo benzene.Milicsanaanteeda aadka u fiican waxay ka dhigaysaa mid ku habboon in lagu kala diro xeryahooda kala duwan ee warshadaha kala duwan sida dawooyinka, polymers iyo dahaarka.Haddii aad u baahan tahay inaad kala dirto resins, balaastikada, ama walxaha kale ee organic, THF waxay bixisaa xalal aad u fiican oo ay weheliso waxtarka sare iyo waxtarka.
Marka lagu daro inuu yahay dareere aad u fiican, THF sidoo kale waa dhexdhexaad muhiim u ah isku dhafka kiimikada.Waxay door muhiim ah ka ciyaartaa falcelino badan, ha ahaato falcelin dhexdhexaad ah ama falcelin lafteeda.Awooddeeda in ay samayso dhismo leh cusbo bir ah iyo isku-dubarid unugyo kala duwan ayaa ka dhigaya dhisme muhiim ah oo soo saarista daawooyinka, agrochemicals iyo kiimikooyinka khaaska ah.Adigoo isticmaalaya THF qayb ka mid ah habka isku dhafka ah, waxaad filan kartaa wax soo saarka iyo heerka falcelinta, hubinta in wax soo saarkaagu yahay mid hufan oo kharash-ool ah.
Marka lagu daro in loo isticmaalo sida dareeraha iyo dhexdhexaadiyaha synthetic, THF sidoo kale waxaa si weyn loogu isticmaalaa falanqeeye falanqeyn ah.Nadiifinteeda sare iyo xasilloonida ayaa ka dhigaysa mid ku habboon farsamooyinka falanqaynta kala duwan sida chromatography gaaska iyo chromatography dareeraha ah.Waxay ka caawisaa in la aqoonsado oo la kala saaro xeryahooda kala duwan ee isku dhafka adag, caawinta helitaanka natiijooyinka falanqaynta saxda ah oo la isku halayn karo.Haddi aad cilmi baadhis ku samaynayso kimisteriga, biochemistry ama sayniska deegaanka, THF waxay u noqon kartaa hanti qiimo leh shaybaadhkaaga.
Marka la soo koobo, tetrahydrofuran (THF) waa xarun isku dhafan oo laga helo codsiyada warshadaha kala duwan.Xalka aadka u wanaagsan, kartida isku-dhafka kiimikaad, iyo falcelinta falanqeyntu waxay ka dhigtaa qayb muhiim ah oo ka mid ah hababka u dhexeeya kala dirida walxaha organic ilaa soo saarista daawooyinka.Iyada oo leh sifooyinkeeda aadka u wanaagsan iyo adeegsigeeda ballaaran, THF waa qalab qiimo leh oo loogu talagalay warshad kasta oo u baahan xalal la isku halleyn karo, dhexdhexaadin wax ku ool ah oo isku dhafan, iyo dib-u-hawlgalayaasha falanqaynta saxda ah.
