    Isicelo

    Embonini yamakha, isetshenziswa njengento eluhlaza ekukhiqizeni i-methyl vanillin ne-ethyl vanillin.

    Isetshenziswa embonini yezemithi njengesidakamizwa esilwa nomfutho wegazi ophakeme i-Atenolol, i-Dp-hydroxyphenylglycine (imithi ephakathi ethuthukiswe kuzwelonke), i-amoxicillin ebanzi ebanzi (ngomlomo), i-acetophenone, i-amino acid nezinye izinhlanganisela I-synthetic intermediate.

    Isetshenziswa njengendawo emaphakathi yezinto zokusetshenziswa zokuvanisha, odayi, amapulasitiki namakhemikhali ezolimo.

    Ingase futhi isetshenziselwe ukukhiqiza i-allantoin. I-Allantoin iyimithi elwa nesilonda esimaphakathi, imikhiqizo yemithi, namakhemikhali ansuku zonke.

    Isitoreji

    Yigcine ivalwe ngokuqinile, gwema ukuthintana nomoya, futhi uyigcine endaweni epholile, eyomile futhi engenawo umoya. Gcina futhi uthuthe ngokuhambisana nemithetho yamakhemikhali anobuthi.

    Izakhiwo zomzimba namakhemikhali

    Lo mkhiqizo uwuketshezi olungenambala noma oluphuzi olukhanyayo. Ixubene namanzi, inyibilika kancane ku-ethanol ne-ether. Ayincibiliki kuma-esters nasezincibilikilweni ezinephunga elimnandi. Isixazululo sizinze ngokwedlulele futhi asiwohloki lapho sibekwe emoyeni, futhi i-glyoxylic acid ikhona efomini elinamanzi esisombululo esinamanzi. Okulimazayo.
