Taw qhia
N-butanol, tseem hu ua butanol, yog cov organic compound, nws yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm n-butanol:
Zoo:
1. Lub cev muaj zog: Nws yog cov kua tsis muaj xim.
2. Cov khoom siv tshuaj lom neeg: Nws tuaj yeem yaj hauv dej thiab cov kuab tshuaj organic, thiab yog ib qho chaw nruab nrab ntawm cov polar compound. Nws tuaj yeem raug oxidized rau butyraldehyde thiab butyric acid, los yog nws tuaj yeem dehydrated los ua butene.
Siv:
1. Muaj kev siv: Nws yog ib qho hnyav hnyav thiab muaj ntau yam kev siv hauv kev lag luam tshuaj xws li coatings, inks, thiab detergents.
2. Kev siv hauv chav kuaj: Nws tuaj yeem siv los ua cov kuab tshuaj los ua kom muaj helical protein folding, thiab feem ntau yog siv rau hauv kev sim tshuaj biochemical los catalyze cov tshuaj tiv thaiv.
Txoj kev:
1. Butylene hydrogenation: Tom qab hydrogenation cov tshuaj tiv thaiv, butene yog reacted nrog hydrogen nyob rau hauv lub xub ntiag ntawm ib tug catalyst (xws li ib tug nickel catalyst) kom tau n-butanol.
2. Cov tshuaj tiv thaiv lub cev qhuav dej: butanol yog reacted nrog cov acids muaj zog (xws li concentrated sulfuric acid) los tsim butene los ntawm lub cev qhuav dej, thiab ces butene yog hydrogenated kom tau n-butanol.
Cov ntaub ntawv kev nyab xeeb:
1. Nws yog cov kua hluav taws kub, tsis txhob sib cuag nrog qhov hluav taws kub, thiab kom deb ntawm cov nplaim taws thiab qhov chaw kub kub.
3. Nws muaj qee yam toxicity, tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus nws vapor.
4. Thaum khaws cia, nws yuav tsum muab cia rau hauv qhov chaw kaw, kom deb ntawm cov oxidants thiab hluav taws kub, thiab khaws cia rau hauv chav tsev kub.
