Isingeniso

I-Octanoic acid iwuketshezi olungenambala olunephunga elingavamile. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-caprylic acid:

 

Ikhwalithi:

- I-Caprylic acid iyi-fatty acid enobuthi obuphansi.

- I-Caprylic acid iyancibilika emanzini nasezincibilikisini eziphilayo njenge-ethanol ne-ether.

 

Sebenzisa:

- Ingasetshenziswa njengesithuthukisi ukunambitheka, ukunambitheka kwekhofi, i-flavour thickener kanye nesidakamizwa esincibilikisa phezulu, njll.

- I-Caprylic acid ingasetshenziswa futhi njenge-emulsifier, i-surfactant, ne-detergent.

 

Indlela:

- Indlela evamile yokulungiselela i-caprylic acid ngokusebenzisa i-transesterification yama-fatty acids nama-alcohol, okungukuthi, i-esterification.

- Indlela evame ukusetshenziswa yokulungisa i-caprylic acid iwukusabela nge-caprylic alcohol ne-sodium hydroxide ukuze kwakheke usawoti we-sodium we-octanol, obese usabela nge-sulfuric acid ukwenza i-caprylic acid.

 

Ulwazi Lokuphepha:

- I-Caprylic acid ngokuvamile iphephile ngaphansi kwezimo ezivamile zokusetshenziswa, kodwa kusafanele kuthathwe ukunakekelwa ukuze kulandelwe indlela efanele yokusebenzisa.

- Uma usebenzisa i-caprylic acid, gqoka amagilavu ​​okuvikela amakhemikhali kanye nezibuko ukuze uvikele isikhumba namehlo.

- Uma uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

- Uma ugcina futhi uphatha i-caprylic acid, gwema ukuthintana nama-oxidants aqinile nezinto ezivuthayo, futhi ugweme ilangabi elivulekile nezindawo ezishisa kakhulu.
