Sodium hydridewaa reagement xoog badan oo badan oo udub dhexaad u ahaa isku dhafka kiimikada tobanaan sano. Sifooyinkeeda gaarka ah iyo codsiyada kala duwan ayaa ka dhigaya qalab lagama maarmaan u ah cilmi-baarayaasha iyo farmashiyeyaasha. Balooggan, waxaan u dhexgeli doonnaa adduunka xiisaha leh ee sodium hydride waxaanan sahamin doonaa doorkeeda kiimikada casriga ah.
Sodium hydride, caanaha kiimikaad ee NaH, waa iskudhis adag oo ka kooban cations sodium iyo anions hydride. Waxaa lagu yaqaanaa sifooyinkeeda yaraynta xooggan waxaana caadi ahaan loo isticmaalaa saldhigga isku-dhafka dabiiciga ah. Mid ka mid ah sifooyinkeeda muhiimka ah ayaa ah awoodda lagu nadiifiyo xeryahooda kala duwan, taasoo ka dhigaysa reagent muhiim u ah diyaarinta noocyo badan oo unugyo organic ah.
Mid ka mid ah isticmaalka ugu muhiimsan ee sodium hydride waa in isku-darka xeryahooda organometallic. Iyaga oo ka falcelinaya sodium hydride oo leh organohalides ama electrophiles kale, farmashiyeyaashu waxay soo saari karaan xeryahooda organonadium, kuwaas oo dhexdhexaadin muhiim ah u ah soo saarista daawooyinka, agrochemicals, iyo sayniska alaabta.
Sodium hydridewuxuu door muhiim ah ka ciyaaraa diyaarinta reagents Grignard kuwaas oo lagama maarmaan u ah isku dhafka organic. Iyaga oo ka falcelinaya sodium hydride oo leh magnesium halide, farmashiyeyaashu waxay abuuri karaan reagents Grignard, kuwaas oo si weyn loo isticmaalo si loo sameeyo curaarta kaarboon-carbon iyo soo bandhigaan kooxaha shaqeeya molecules organic.
Marka lagu daro doorka ay ku leedahay kiimikada organometallic, sodium hydride waxaa loo isticmaalaa soo saarista dawooyin kala duwan iyo kiimikooyin fiican. Awooddeeda inay si xushmad leh u baabi'iso kooxo hawleed gaar ah ayaa ka dhigaysa qalab qiimo leh oo loogu talagalay farmashiyaasha ka shaqeeya sahaminta iyo horumarinta daroogada.
Intaa waxaa dheer,sodium hydrideWaxa kale oo ay leedahay codsiyo ku jira kimistariga polymer, halkaas oo loo isticmaali karo wax ka beddelka polymers iyo isku-darka polymers-ka gaarka ah ee leh sifooyin gaar ah. Dareen-celinteeda sare iyo xulashada doorashadu waxay ka dhigaysaa reagent doorashada isbeddellada kakan ee sayniska polymer.
Inkasta oo si ballaaran loo isticmaalo, waxaa muhiim ah in la ogaado in sodium hydride waa in si taxadar leh loo maareeyo sababtoo ah sifooyinka pyrophoric. Tallaabooyinka badbaadada ku habboon iyo hababka maaraynta waa in la raaco si loo hubiyo isticmaalka badbaadada leh ee qalabkan shaybaarka.
Isku soo wada duuboosodium hydridewaa qalab wax ku ool ah oo lagama maarmaanka u ah isku dhafka kiimikada. Falcelinteeda gaarka ah iyo ku-dhaqankeeda ballaadhan ayaa ka dhigaya mid muhiim u ah faylalka farmashiistaha synthetic. Maaddaama cilmi-baarista kiimikada organic iyo organometallic ay sii socoto inay hore u sii socoto, muhiimada sodium hydride ee qaabeynta muuqaalka casriga ah ee isku-dhafka kiimikada lama soo koobi karo.
