Isingeniso

I-Vanillin propyl glycol acetal iyinhlanganisela yezinto eziphilayo.

 

Ikhwalithi:

I-Vanillin propylene glycol acetal iwuketshezi olungenambala ukuya kokuphuzi olunephunga eliyingqayizivele elifana nephunga le-vanilla. Iyancibilika otshwaleni nasezincibilikisini ze-ether futhi ayincibiliki emanzini.

 

Sebenzisa:

 

Indlela:

I-Vanillin propylene glycol acetal ingatholakala ngokusabela kwe-vanillin ne-propylene glycol acetal ngaphansi kwezimo ze-alkaline. Ngaphansi kwezimo ze-alkaline, i-vanillin ihlangana ne-propylene glycol acetal yakhe i-vanillin propylene glycol acetal.

 

Ulwazi Lokuphepha:

Kuyaqondakala ukuthi i-vanillin propylene glycol acetal ngokuvamile iphephile ngaphansi kwezimo ezivamile zokusetshenziswa, kodwa lezi zindaba ezilandelayo kufanele ziqashelwe:

Gwema ukuthinta i-vanillin, i-propylene glycol, i-acetal enesikhumba, amehlo kanye nolwelwesi lwamafinyila.

Gqoka izinyathelo zokuzivikela ezifanele, njengamagilavu ​​nezibuko, lapho uyisebenzisa.

Ngesikhathi sokugcina nokuphatha, kuyadingeka ukugwema ukuthungela nokushisa okuphezulu ukuze kuvikelwe ekushiseni noma ukuqhuma.
