Intshayelelo

I-4-Methylvaleric acid, eyaziwa ngokuba yi-isovaleric acid, i-organic compound. Oku kulandelayo yintshayelelo emfutshane ngobume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

- Ukunyibilika: Ukunyibilika emanzini kunye nezinyibilikisi eziphilayo

- Ivumba: Inevumba elimuncu elifana ne-acetic acid

 

Sebenzisa:

- Kwishishini levumba, linokusetyenziswa ukwenza iincasa zeziqhamo, imifuno kunye ne-confectionery.

- Kwishishini leengubo, lisetyenziswa njenge-solvent kunye ne-plasticizer.

 

Indlela:

- I-4-Methylpentanoic acid inokulungiswa ngokuphendula kwe-isovaleric acid kunye ne-carbon monoxide phambi kokukhanya.

-I-Catalysts ezifana ne-aluminiyamu okanye i-potassium carbonate zihlala zisetyenziselwa ukusabela.

 

Ulwazi ngoKhuseleko:

- I-4-Methylpentanoic acid iyilwelo olunokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye nokushisa okuphezulu.

- Nxiba izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu kunye nokukhusela amehlo, xa usetyenziswa.

- Kuphephe ukuphefumla, ukungeniswa, okanye ukudibana nesikhumba kunye namehlo ngexesha lokuphatha.
