Isingeniso

I-N-butanol, eyaziwa nangokuthi i-butanol, iyinhlanganisela yezinto eziphilayo, iwuketshezi olungenambala olunephunga elidakayo elingavamile. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-n-butanol:

Ikhwalithi:

1. Izici ezingokomzimba: Iwuketshezi olungenambala.

2. Izakhiwo zamakhemikhali: Ingancibilika emanzini nasezincibilikiseni eziphilayo, futhi iyinhlanganisela ye-polar elinganiselwe. Ingafakwa i-oxidized ibe i-butyraldehyde ne-butyric acid, noma ingaphelelwa amanzi ukuze yakhe i-butene.

Sebenzisa:

1. Ukusetshenziswa kwezimboni: Kuyi-solvent ebalulekile futhi inohlu olubanzi lwezinto ezisetshenziswayo embonini yamakhemikhali njengezinto zokumboza, oyinki, nezihlanzi.

2. Ukusetshenziswa kwelabhorethri: Ingasetshenziswa njengesinyibilikisi ukuze ihehe ukugoqa amaprotheni e-helical, futhi ivame ukusetshenziswa ekuhloleni kwamakhemikhali ezinto eziphilayo ukuze kubangele ukusabela.

Indlela:

1. I-Butylene hydrogenation: Ngemva kokusabela kwe-hydrogenation, i-butene iphendulwa nge-hydrogen phambi kwe-catalyst (njenge-nickel catalyst) ukuze kutholwe i-n-butanol.

2. Ukusabela kokuphelelwa amanzi emzimbeni: i-butanol isabela nge-acids eqinile (njenge-concentrated sulfuric acid) ukuze ikhiqize i-butene ngokusabela kokuphelelwa amanzi emzimbeni, bese i-butene i-hydrogenated ukuze ithole i-n-butanol.

Ulwazi Lokuphepha:

1. Iwuketshezi oluvutha umlilo, gwema ukuthintana nomthombo womlilo, futhi ugweme amalangabi avulekile nezimo zokushisa eziphezulu.

3. Inobuthi obuthile, gwema ukuthintana ngqo nesikhumba namehlo, futhi gwema ukuhogela umhwamuko wayo.

4. Uma uyigcina, kufanele igcinwe endaweni evaliwe, kude nama-oxidants nemithombo yomlilo, futhi igcinwe endaweni epholile.
