Intshayelelo

I-2-Methylfran i-organic compound kunye ne-chemical formula C5H6O kunye ne-molecular weight 82.10g / mol. Oku kulandelayo yinkcazo yendalo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko lwe-2-Methylfran:

 

Indalo:

-Imbonakalo: ulwelo olungenambala

-Ivumba: Ngevumba le-aldehyde

-Indawo yokubila: 83-84 ° C

-Ubuninzi: malunga. 0.94 g/mL

-Ukunyibilika: Inyibilika emanzini, ethanol, ether kunye nezinye izinyibilikisi eziphilayo

 

Sebenzisa:

- I-2-Methylfran isetyenziswa kakhulu njenge-solvent kunye ne-intermediate kwi-organic synthesis

-inokusetyenziselwa ukuhlanganiswa kwe-furan carboxylic acid, i-ketone, i-carboxylic acid kunye nezinye izinto eziphilayo

-Isetyenziswa kakhulu kwimichiza, izitshabalalisi kunye neendawo zeziqholo

 

Indlela yokulungiselela:

-Indlela eqhelekileyo yokulungiselela i-acid-catalyzed reaction ye-aldehyde kunye ne-polyethanolamine

-Inokuthi yenziwe ngokusabela kwe-formic acid kunye nepyrazine

-Inokufumaneka kwakhona ngokuphendula i-butyl lithium oxide kunye ne-N-methyl-N- (2-bromoethyl) i-aniline, kwaye emva koko nge-acid catalysis.

 

Ulwazi ngoKhuseleko:

I-2-Methylfran inetyhefu ethile emzimbeni womntu kwiqondo lobushushu begumbi, kwaye iyacaphukisa emehlweni kunye nolusu.

-Kuphephe ukuphefumla, ukudibana nesikhumba kunye namehlo xa usebenzisa

-Sebenzisa ngeeglavu zokhuselo ezifanelekileyo, iiglasi kunye nempahla yokhuselo

-Sebenzisa kwindawo engenamoya ukuphepha ukuvela kwemixube enokutsha okanye eqhumayo

-Zigcine kude nobushushu kunye nomlilo kwaye kwindawo epholileyo neyomileyo

-Jonga kumaphepha edatha yokhuseleko olufanelekileyo kunye nezikhokelo zokuqinisekisa ukusebenza ngokukhuselekileyo kunye nokugcinwa

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
