Kwembula amandla weSodium Hydride: Ithuluzi eliguquguqukayo ku-Synthesis yamakhemikhali

I-sodium hydrideIngabe i-realent enamandla futhi eguquguqukayo eye yayisisekelo se-synthersos yamakhemikhali amashumi eminyaka. Izakhiwo zayo ezihlukile nezinhlobonhlobo zezicelo zikwenza ithuluzi elibalulekile labaphenyi namakhemikhali. Kule bhulogi, sizokwelulela ezweni elihehayo leSodium Hydride futhi lihlole indima yalo kumakhemikhali anamuhla.

I-Sodium hydride, ifomula yamakhemikhali nah, iyindawo eqinile ehlanganiswa ama-sodium amaza ka-sodium kanye ne-hydride anions. Kuyaziwa ngezakhiwo zayo eziqinile ezinciphisa futhi zivame ukusetshenziswa njengesisekelo ekuhlolweni kwe-organic. Enye yezimfanelo zayo ezibalulekile yikhono lokuncipha ezahlukene zezinhlanganisela, okwenza kube yi-reagent ebalulekile yokulungiselela ama-molecule ahlukahlukene.

Okunye ukusetshenziswa okubaluleke kakhulu kweSodium Hydride kusesimweni sokuhlanganiswa kwezifo. Ngokuphendula i-sodium hydride ngama-organohalides noma amanye ama-electroophilel, amakhemikhali angakhiqiza amakhompiyutha we-organium, abalulekile abasebenza ngokukhiqizwa kwemithi, ama-agrochemicals kanye nezinto zokwakha.

I-sodium hydrideUdlala indima ebalulekile ekuhlelweni kwe-grignard reagents ebaluleke kakhulu ekuhlolweni kwe-organic. Ngokuphendula i-sodium hydride nge-magnesium halide, amakhemikhali angadala ama-reagents asemlundweni, asetshenziswa kabanzi ukwakha amabhodlela e-carbon-carbon futhi angenise amaqembu asebenzayo kuma-molecule asebenzayo.

Ngaphezu kwendima yayo kumakhemikhali we-organometallic, i-sodium hydride isetshenziswa ekukhiqizweni kwemithi ehlukahlukene yamakhemikhali namakhemikhali amahle. Amandla awo okunciphisa ukuncipha kwamaqembu athile athile ngokukhetha enza ithuluzi elibalulekile losokhemisi abasebenza ekutholweni kwezidakamizwa nasekuthuthukisweni kwezidakamizwa.

Ngaphezu kwalokho,i-sodium hydrideFuthi inezicelo kumakhemikhali we-polymer, lapho ingasetshenziselwa ukuguqulwa kwama-polymers kanye nokuhlanganiswa kwama-polymers akhethekile anezakhiwo ezifanele. Ukuvuselelwa kwayo okuphezulu nokukhetha kwayo kwenza kube yi-realent yokuzikhethela kokuguqulwa okuyinkimbinkimbi ku-polymer science.

Yize isetshenziswa kabanzi, kubalulekile ukuqaphela ukuthi i-sodium hydride kufanele iphathwe ngokuqapha ngenxa yezakhiwo zayo ze-pyrophoric. Izinyathelo ezifanele zokuphepha kanye nezinqubo zokuphatha kufanele zilandelwe ukuqinisekisa ukusetshenziswa okuphephile kwale mpendulo yelebhu.

Ngokufigqiwe,i-sodium hydrideiyithuluzi eliguquguqukayo futhi elisemqoka ku-synthesis yamakhemikhali. Ukuvuselelwa kwayo okuhlukile nokusebenza okubanzi kwenza kube ukwengeza okubalulekile kwiphothifoliyo yokwenziwa kwamakhemikhali. Njengoba ucwaningo ku-Chemistry ye-Organic nase-Orgamometallic luyaqhubeka ukuqhubekisela phambili phambili, ukubaluleka kwe-sodium hydride ekwakheni umhlaba wanamuhla wokuhlanganiswa kwamakhemikhali akunakweqiswa.
