Intshayelelo

Isoamyl acetate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-isoamyl acetate:

 

Umgangatho:

1. Imbonakalo: ulwelo olungenambala.

2. Imvakalelo yokujoja: Kukho ivumba elifana nesiqhamo.

3. Ubuninzi: malunga ne-0.87 g / cm3.

5. Ukunyibilika: ukunyibilika kwiintlobo ezahlukeneyo zezinyibilikisi eziphilayo, ezifana ne-alcohol kunye ne-ethers.

 

Sebenzisa:

1. Isetyenziswa kakhulu njenge-solvent kwi-industry, engasetyenziselwa ukutshabalalisa i-resin, iingubo, iidayi kunye nezinye izinto.

2. Isenokusetyenziswa njengesithako sevumba elimnandi, esifumaneka kwincasa yeziqhamo.

3. Kwi-organic synthesis, inokusetyenziswa njengenye yee-reagents ze-esterification reaction.

 

Indlela:

Iindlela zamalungiselelo e-isoamyl acetate ikakhulu zezi zilandelayo:

1. I-Esterification reaction: i-isoamyl yotywala iphendulwa nge-acetic acid phantsi kweemeko ze-acidic ukuvelisa i-isoamyl acetate kunye namanzi.

2. Impendulo ye-Etherification: I-isoamyl alcohol iphendulwa nge-acetic acid phantsi kweemeko ze-alkaline ukuvelisa i-isoamyl acetate kunye namanzi.

 

Ulwazi ngoKhuseleko:

1. I-isoamyl acetate iyilwelo oluvuthayo kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu.

2. Nxiba iiglavu ezifanelekileyo kunye neglasi xa usebenzisa ukuthintela ukudibana nolusu kunye namehlo.

3. Kuphephe ukuphefumla umphunga wento kwaye uqinisekise ukuba indawo yokusebenza ingena umoya.

4. Ukuba uyaginya, uphefumle okanye udibane nezixa ezikhulu zechiza, funa unyango ngokukhawuleza.

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