Taw qhia
Sodium triacetoxyborohydride yog ib qho organoboron compound nrog cov tshuaj formula C6H10BNaO6. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1. Cov tsos mob: Sodium triacetoxyborohydride feem ntau yog cov xim tsis muaj xim crystalline.
2. Stability: Nws yog qhov ruaj khov ntawm chav tsev kub thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic.
3. Toxicity: Sodium triacetoxyborohydride muaj tshuaj lom tsawg dua piv rau lwm cov tshuaj boron.
Siv:
1. Tus neeg sawv cev txo qis: Sodium triacetoxyborohydride yog ib qho tshuaj txo qis rau cov organic synthesis, uas tuaj yeem txo cov aldehydes, ketones thiab lwm yam sib xyaw ua ke rau cov cawv sib xws.
2. Catalyst: Sodium triacetoxyborohydride tuaj yeem siv los ua cov catalyst hauv qee cov organic synthesis, xws li Bar-Fischer ester synthesis thiab Swiss-Haussmann cov tshuaj tiv thaiv.
Txoj kev:
Txoj kev npaj ntawm triacetoxyborohydride feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm triacetoxyborohydride nrog sodium hydroxide. Rau cov txheej txheem tshwj xeeb, thov xa mus rau phau ntawv qhia txog kev sib xyaw tshuaj lom neeg thiab lwm yam ntaub ntawv uas cuam tshuam.
Cov ntaub ntawv kev nyab xeeb:
1. Sodium triacetoxyborohydride ua rau khaus tawv nqaij thiab qhov muag, yog li yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag thaum lub sijhawm ua haujlwm, thiab hnav cov hnab looj tes tiv thaiv thiab tsom iav yog tias tsim nyog.
2. Thaum khaws cia thiab tuav, tsis txhob sib cuag nrog dej vapor nyob rau hauv cov huab cua vim nws rhiab heev rau dej thiab yuav decompose.
Muab qhov tshwj xeeb ntawm cov tshuaj, thov siv thiab tswj lawv raws li kev qhia ntawm tus kws tshaj lij.
