Isingeniso

I-4-Methylvaleric acid, eyaziwa nangokuthi i-isovaleric acid, iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane ngobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- I-Solubility: Incibilika emanzini nasezincibilikisini eziphilayo

- Iphunga: Inephunga elimuncu elifana ne-acetic acid

 

Sebenzisa:

- Embonini yephunga, ingasetshenziswa ukuhlanganisa ukunambitheka kwezithelo, imifino kanye ne-confectionery.

- Embonini yokugqoka, isetshenziswa njenge-solvent ne-plasticizer.

 

Indlela:

- I-4-Methylpentanoic acid ingalungiswa ngokusabela kwe-isovaleric acid ne-carbon monoxide phambi kokukhanya.

- Ama-catalysts afana ne-aluminic acid noma i-potassium carbonate avame ukusetshenziswa ekuphenduleni.

 

Ulwazi Lokuphepha:

- I-4-Methylpentanoic acid iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.

- Gqoka okokuvikela okufanele, njengamagilavu ​​nokuvikela amehlo, lapho usetshenziswa.

- Gwema ukuhogela, ukumunca, noma ukuthinta isikhumba namehlo ngesikhathi sokuphatha.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
