Isifundo se-in vitro I-Vanillylacetone ifana nesakhiwo samakhemikhali kwamanye amakhemikhali anephunga elimnandi njenge-vanillin ne-eugenol. Isetshenziswa njengesengezo sokunandisa emafutheni esesame namakha ukwethula ukunambitheka kwesinongo. I-ginger ayinayo i-vanillylacetone; Ujinja uguqulelwa ku-gingerol ngokupheka, okuyisibonelo samanje sokuguqulelwa ku-vanillylacetone ngokusabela kwe-aldol condensation. I-Vanillylacetone ingaba yisithako esisebenzayo sejinja ukuze ibe nomthelela wokulwa nohudo.

Isingeniso

I-4-4-Hydroxy-3-methoxybutyl-2-one, eyaziwa nangokuthi i-4-hydroxy-3-methoxypentanone, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso kwezinye zezakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi oluphuzi olungenambala noma olukhanyayo noma oluqinile.

- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njenge-ethanol ne-dimethylformamide, ezingancibiliki emanzini.

- Ubuthi: Inhlanganisela inobuthi futhi idinga izinyathelo zokuphepha ezidingekayo lapho uhogela umoya noma uthintana nesikhumba.

 

Sebenzisa:

- Izivivinyo zeKhemistry: Ingasetshenziswa futhi njenge-reagent yezivivinyo ezithile zamakhemikhali.

 

Indlela:

Indlela yokulungiselela ye-4-4-hydroxy-3-methoxybutyl-2-one ingafinyelelwa nge-organic synthesis ngaphansi kwezimo ezifanele. Kungase kube nezindlela eziningana zokuyilungiselela, kodwa nansi enye yezindlela ezingenzeka:

Chaza inani elifanele le-pentanone ku-solvent yemvelo.

Engeza isixazululo se-sodium hydroxide ngokweqile.

Emazingeni okushisa angapheli kanye nengcindezi, i-methanol yengezwa kancane kancane engxubeni yokusabela.

Ngokungezwa kwe-methanol, i-4-4-hydroxy-3-methoxybutyl-2-one yakheka engxenyeni yokusabela.

Umkhiqizo uphinde ucutshungulwe futhi uhlanzwe ukuze uthole inhlanganisela yokugcina.

 

Ulwazi Lokuphepha:

- Le nhlanganisela inobuthi ngandlela-thile futhi kufanele igwenywe ngokuhogela ngokuqondile noma ukuthintana kwesikhumba.

- Izinyathelo zokuphepha ezifanele kufanele zithathwe lapho zisetshenziswa, njengokugqoka izibuko zamakhemikhali, ukugqoka amagilavu ​​amakhemikhali kanye nezingubo zokuzivikela.

- Ukulahlwa kwemfucuza: Imfucuza ixutshwa nezincibilikisi ezifanele bese ilahlwa ngendawo yokulahla imfucuza efanele ngokuhambisana nemithetho yendawo.
