Sodium hydrideisimba guru uye rinogona kushandiswa zvakasiyana-siyana rave riri musimboti wekugadzirwa kwemakemikari kwemakumi emakore. Hunhu hwayo hwakasiyana uye mashandisirwo akasiyana-siyana anoita kuti ive chishandiso chakakosha kune vaongorori nevanoongorora makemikari. Mublog rino, tichaongorora nyika inonakidza ye sodium hydride uye toongorora basa rayo mukemistri yemazuva ano.
Sodium hydride, makemikari fomura NaH, chinhu chakasimba chinoumbwa ne sodium cations uye hydride anions. Inozivikanwa nehukuru hwayo hwekuderedza simba uye inowanzoshandiswa sehwaro mukugadzirwa kweorganic. Chimwe chezvinhu zvikuru zvayo kugona kubvisa protonate yemakomikoro akasiyana-siyana, zvichiita kuti ive reagent yakakosha pakugadzirira mamorekuru akasiyana-siyana eorganic.
Imwe yenzira dzakakosha dzekushandisa sodium hydride ndeyekugadzira macompounds e organometallic. Nekushandisa sodium hydride ne organohalides kana mamwe ma electrophiles, ma chemistry anogona kugadzira macompounds e organonadium, ayo ari ma intermediates akakosha mukugadzirwa kwemishonga, agrochemicals, uye materials science.
Sodium hydrideinoita basa guru mukugadzirira maGrignard reagents akakosha mukugadzirwa kweorganic. Nekushandisa sodium hydride nemagnesium halide, machemist anogona kugadzira maGrignard reagents, anoshandiswa zvakanyanya kugadzira carbon-carbon bonds uye kuunza mapoka anoshanda mumamorekuru eorganic.
Pamusoro pebasa rayo mumakemikari e-organometallic, sodium hydride inoshandiswa mukugadzira mishonga yakasiyana-siyana uye makemikari akanaka. Kugona kwayo kubvisa mapuroteni mumapoka anoshanda kunoita kuti ive chishandiso chakakosha kune vanogadzira mishonga vanoshanda mukutsvaga nekugadzira mishonga.
Pamusoro pe,sodium hydrideInoshandiswawo mu polymer chemistry, uko inogona kushandiswa pakushandura ma polymer uye kugadzira ma polymer akakosha ane hunhu hwakagadzirwa. Kugona kwayo kuita zvinhu zvakasiyana-siyana uye kusarudza kunoita kuti ive reagent inosarudzwa pakuchinja kwakaoma mune sainzi ye polymer.
Kunyangwe ichishandiswa zvakanyanya, zvakakosha kuziva kuti sodium hydride inofanira kubatwa nekungwarira nekuda kwehunhu hwayo hwe pyrophoric. Matanho akakodzera ekuchengetedza uye maitiro ekubata anofanirwa kuteverwa kuti ive nechokwadi chekushandiswa kwakachengeteka kwe reagent iyi murabhoritari.
Muchidimbu,sodium hydridechishandiso chinoshandiswa zvakasiyana-siyana uye chisingadhuri mukugadzirwa kwemakemikari. Kushanda kwaro kwakasiyana uye kushanda kwaro kwakafara kunoita kuti rive chinhu chakakosha mukugadzirwa kwemakemikari ekugadzira. Sezvo tsvakiridzo mumakemikari eorganic neorganometallic ichiramba ichifambira mberi, kukosha kwesodium hydride mukugadzira mamiriro emazuva ano ekugadzirwa kwemakemikari hakugone kupfuudzwa zvakanyanya.
