Isifundo se-in vitro I-Vanillylacetone ifana nesakhiwo sekhemikhali kwezinye iikhemikhali zevumba ezifana ne-vanillin kunye ne-eugenol. Isetyenziswa njengesithambiso kwi-oyile yesesame kunye neziqholo ukwazisa incasa yesiqholo. I-Ginger ayinayo i-vanillylacetone; I-Ginger iguqulwa ibe yi-gingerol ngokupheka, ngumzekelo wangoku wokuguqulwa kwi-vanillylacetone nge-aldol condensation reaction. I-Vanillylacetone inokuba sisithako esisebenzayo sejinja ukwenza i-antidiarrheal effect.

Intshayelelo

I-4-4-Hydroxy-3-methoxybutyl-2-one, eyaziwa ngokuba yi-4-hydroxy-3-methoxypentanone, i-organic compound. Oku kulandelayo sintshayelelo kwezinye iipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala okanye olukhanyayo olutyheli okanye oluqinileyo.

- Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-dimethylformamide, ezinganyibilikiyo emanzini.

- Ubuthi: Ikhompawundi inetyhefu kwaye ifuna amanyathelo okhuseleko ayimfuneko xa uphefumla okanye udibana nolusu.

 

Sebenzisa:

- Imifuniselo yeKhemistry: Isenokusetyenziswa njenge-reagent kwimifuniselo ethile yekhemistri.

 

Indlela:

Indlela yokulungiselela i-4-4-hydroxy-3-methoxybutyl-2-enye inokufezekiswa ngokuhlanganiswa kwezinto eziphilayo phantsi kweemeko ezifanelekileyo. Kukho iindlela ezininzi zokuyilungiselela, kodwa nantsi enye yeendlela ezinokwenzeka:

Nyibilikisa isixa esifanelekileyo sepentanone kwisinyibilikisi sendalo.

Yongeza isisombululo sesodium hydroxide engaphezulu.

Kwiqondo lobushushu elingaguqukiyo kunye noxinzelelo, i-methanol yongezwa kancinci kancinci kumxube wokuphendula.

Ngokudibanisa i-methanol, i-4-4-hydroxy-3-methoxybutyl-2-enye yenziwa kumxube wokuphendula.

Imveliso iqhutyelwa phambili kwaye ihlanjululwe ukufumana ikhompawundi yokugqibela.

 

Ulwazi ngoKhuseleko:

- Le khompawundi iyityhefu ngandlel 'ithile kwaye kufuneka ithintelwe ngokuphefumla ngokuthe ngqo okanye ukudibana kwesikhumba.

- Amanyathelo afanelekileyo okhuseleko kufuneka athatyathwe xa esetyenziswa, anje ngokunxiba iiglasi zeekhemikhali, ukunxiba iiglavu zekhemikhali kunye nempahla yokuzikhusela.

- Ukulahlwa kwenkunkuma: Inkunkuma ixutywa nezinyibilikisi ezifanelekileyo kwaye ilahlwe yindawo yokulahla inkunkuma efanelekileyo ngokwemigaqo yendawo.

 

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