Intshayelelo

Umgangatho:

1. I-Myricetaldehyde lulwelo olungenambala olunyibilikayo kwi-ethanol, i-ether kunye nezinye izinyibilikisi eziphilayo.

2. Ineempawu ezikhethekileyo zevumba, kwaye iinqununu zayo zi-α-linaloal kunye ne-myriceol.

 

Indlela:

Ukulungiswa kwe-myricetaldehyde kudla ngokuxutywa. Indlela yokulungiselela esetyenziswa ngokuqhelekileyo ifumaneka nge-oxyoxyesterification ye-hydroxybenzaldehyde kunye ne-butanone alcohol, kwaye i-myricetaldehyde ifunyenwe ngokusabela kokuphelelwa ngamanzi emzimbeni. Inokufunyanwa nangezinye iindlela zokuyila.

 

Ulwazi ngoKhuseleko:

1. I-Bayricetaldehyde iyacaphukisa kwaye inokubangela ukuphazamiseka xa udibana nesikhumba, ngoko kufuneka ubeke ingqalelo kwimilinganiselo yokukhusela xa uyisebenzisa, njengokugqoka iiglavu.

2. Gwema ukuphefumla igesi ye-myricetaldehyde ukuze ugweme imiphumo emibi kwindlela yokuphefumula.

3. Gcina i-bayricealdehyde kwindawo epholileyo, nengena umoya, kwaye ugweme ukudibanisa nezinto ezinokutsha ukukhusela umlilo.
