Intshayelelo

I-N-butanol, ekwabizwa ngokuba yi-butanol, yi-organic compound, ilulwelo olungenambala olunevumba elikhethekileyo lotywala. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-n-butanol:

Umgangatho:

1. Iimpawu ezibonakalayo: Lulwelo olungenambala.

2. Iimpawu zeMichiza: Iyakwazi ukuchithwa emanzini kunye ne-solvents ye-organic, kwaye i-compound ye-polar ephakathi. Inokuthi ifakwe i-oxidized kwi-butyraldehyde kunye ne-asidi ye-butyric, okanye inokuthi ikhutshwe emanzini ukuze yenze i-butene.

Sebenzisa:

1. Ukusetyenziswa kwemizi-mveliso: Yinto enyibilikayo ebalulekileyo kwaye inoluhlu olubanzi lwezicelo kwishishini lemichiza njengee-coatings, ii-inki, kunye ne-detergents.

2. Ukusetyenziswa kweLabhoratri: Ingasetyenziselwa njenge-solvent ukuze ifake i-helical protein folding, kwaye isoloko isetyenziswa kwiimvavanyo ze-biochemical ukuze i-catalyze reactions.

Indlela:

1. I-Butylene hydrogenation: Emva kwe-hydrogenation reaction, i-butene iphendulwa kunye ne-hydrogen phambi kwe-catalyst (efana ne-nickel catalyst) ukufumana i-n-butanol.

2. Ukusabela kwe-dehydration: i-butanol iphendulwa nge-acids eqinile (efana ne-concentrated sulfuric acid) ukuvelisa i-butene ngokusabela kwe-dehydration, kwaye ke i-butene i-hydrogenated ukufumana i-n-butanol.

Ulwazi ngoKhuseleko:

1. Ingulwelo olunokutsha, ugweme ukudibanisa nomthombo womlilo, kwaye ugcine kude namadangatye avulekileyo kunye neendawo zokushisa eziphezulu.

3. Inetyhefu ethile, kuphephe ukudibana ngokuthe ngqo nolusu namehlo, kwaye uphephe ukuphefumla umphunga wayo.

4. Xa ugcina, kufuneka ugcinwe kwindawo evaliweyo, kude ne-oxidants kunye nemithombo yomlilo, kwaye igcinwe kwiqondo lokushisa.
