    Isicelo

    1. Yisinongo esikhulu sembali ye-Hawthorn, ubhekilanga kanye ne-lilac flavour.

    2. Isetshenziswa njengephunga elimnandi kumnduze wesigodi.

    3. Isetshenziswa njengesilungisi ku-Osmanthus fragrans.

    4. Ingasetshenziswa futhi ekunambithekeni kwansuku zonke kanye nezinongo zokudla.

    Impahla

    Iyancibilika ku-ethanol, i-ethyl ether, benzene nezinye izincibilikisi eziphilayo, futhi incibilika emanzini.

    Isitoreji

    Igcinwe endaweni eyomile, enomthunzi, nengena umoya.

    Ukuzinza

    1. Igesi nomoya wayo kwakha ingxube eqhumayo. Gqoka izibuko zokuzivikela, izingubo zokuzivikela, namagilavu ​​okuzivikela.

    2. Hlangana namahlamvu kagwayi kanye nentuthu.

    3. Itholakala ngokwemvelo emafutheni abalulekile njengamafutha enkanyezi ye-anise, amafutha e-cumin, amafutha e-star anise, amafutha e-dill, amafutha omtholo, namafutha ommbila.

    4. Ayizinzile kakhulu ekukhanyeni, kulula ukwenza i-oxidize futhi iguqule umbala emoyeni ukuze ikhiqize i-anisic acid.

    5. I-p-Methoxybenzaldehyde ingasetshenziswa ukuvikela ama-diol, ama-dithiol, ama-amine, ama-hydroxylamine nama-diamine.

    Ukuvikelwa kwe-diol i-p-methoxybenzaldehyde ingakhiwa kalula ngokusabela kwe-diol ne-aldehyde ukwenza i-acetal. I-catalyst esetshenzisiwe ingaba i-hydrochloric acid noma i-zinc chloride, noma ezinye izindlela ezifana ne-iodine catalysis kanye ne-polyaniline njengesithwali se-Sulfuric acid catalysis, i-indium trichloride catalysis, i-bismuth nitrate catalysis, njll. I-P-methoxybenzaldehyde isabela nge-L-cysteine ​​​​ukuthola i-thiazole okuphuma kokunye.

    Ukusabela ngamaqembu e-amino i-P-methoxybenzaldehyde ingasabela namaqembu e-amino ukuze kwakhe izisekelo ze-Schiff, ezincishiswa yi-NaBH4 ukuze zakhe ama-amine esibili.

    Ukwakhiwa kokuphuma kokuphuma kwe-ethylene oxide i-p-methoxybenzaldehyde kungasabela ngama-ylide esibabule ukuze kwakhe okuphuma ethylene oxide, futhi kungasabela nezinhlanganisela ze-diazonium ukuze kutholwe okuphuma okunjalo. Ukusabela ngokuphuma kokuphuma kwe-ethylene oxide nakho kunganweba iringi ukuze kutholwe okuphuma kokuphuma kweringi ye-furan.

    Ukusabela kwe-Diacylation Ngaphansi kwe-catalysis ye-tetrabutylammonium bromide (TBATB), i-p-methoxybenzaldehyde ingasabela nge-acid anhydride ukuze yakhe imikhiqizo ye-diacylation.

    Ekuphenduleni kokuhlanganiswa, ngenxa yomphumela oqinile wokunikela nge-electron weqembu le-para-methoxy, i-p-methoxybenzaldehyde isabela ne-alyltrimethylsilane ngaphansi kwe-catalysis ye-bismuth trifluorosulfonate ukuze kutholwe umkhiqizo odayiliwe .
