    Kachulukidwe: 1.121 g/ml

    Phukusi: 1 L / botolo, 25 L / ng'oma, 200 L / ng'oma

    Kufotokozera

    Zinthu Zofotokozera
    Maonekedwe Madzi opanda mtundu
    Chiyero ≥99.5%
    Mtundu(Co-Pt) ≤20
    Acidity (mgKOH/g) ≤5
    Madzi ≤0.5%

    Kugwiritsa ntchito

    1. Ndilo zokometsera zazikulu mu maluwa a Hawthorn, mpendadzuwa ndi kukoma kwa lilac.

    2. Amagwiritsidwa ntchito ngati mankhwala onunkhira mu kakombo wa m'chigwa.

    3. Amagwiritsidwa ntchito ngati chosinthira mumafuta onunkhira a Osmanthus.

    4. Itha kugwiritsidwanso ntchito pazokometsera zatsiku ndi tsiku ndi zokometsera zazakudya.

    Katundu

    Amasungunuka mu ethanol, sungunuka mu ethyl ether, benzene ndi zosungunulira zina organic, komanso sungunuka m'madzi.

    Kusungirako

    Kusungidwa pa youma, pamthunzi, podutsa mpweya malo.

    Kukhazikika

    1. Mpweya wake ndi mpweya wake zimapanga chisakanizo chophulika. Valani magalasi oteteza, zovala zodzitchinjiriza, ndi magolovesi oteteza.

    2. Kukhala mu masamba a fodya ndi kusuta.

    3. Mwachibadwa amapezeka mumafuta ofunikira monga mafuta a anise star, mafuta a chitowe, mafuta a anise a nyenyezi, mafuta a dill, mafuta a mthethe, ndi mafuta a chimanga.

    4. Sizikhazikika kwambiri pakuwala, ndizosavuta kutulutsa oxidize ndikusintha mtundu mumlengalenga kuti mupange asidi wa anisic.

    5. p-Methoxybenzaldehyde ingagwiritsidwe ntchito kuteteza diols, dithiols, amines, hydroxylamines ndi diamines.

    Chitetezo cha diol p-methoxybenzaldehyde chikhoza kupangidwa mosavuta ndi momwe diol ndi aldehyde zimapangidwira kupanga acetal. Chothandizira chomwe chimagwiritsidwa ntchito chingakhale hydrochloric acid kapena zinc chloride, kapena njira zina monga catalysis ya ayodini ndi polyaniline monga chonyamulira cha Sulfuric acid catalysis, indium trichloride catalysis, bismuth nitrate catalysis, etc. P-methoxybenzaldehyde imakhudzidwa ndi L-cysteine ​​​​kuti ipeze thiazole zotumphukira.

    Kuchita ndi magulu amino a P-methoxybenzaldehyde amatha kuchitapo kanthu ndi magulu a amino kuti apange maziko a Schiff, omwe amachepetsedwa ndi NaBH4 kuti apange ma amine achiwiri.

    Mapangidwe a ethylene oxide zotumphukira p-methoxybenzaldehyde amatha kuchitapo kanthu ndi sulfure ylides kupanga zotumphukira za ethylene oxide, komanso amatha kuchitapo kanthu ndi mankhwala a diazonium kuti apeze zotumphukira zotere. Kuchita ndi zotumphukira za ethylene oxide kumathanso kukulitsa mphete kuti mupeze zotumphukira za mphete za furan.

    Diacylation reaction Pansi pa catalysis ya tetrabutylammonium bromide (TBATB), p-methoxybenzaldehyde imatha kuchitapo kanthu ndi acid anhydride kupanga zinthu zotulutsa diacylation.

    Pogwirizana, chifukwa cha mphamvu yamphamvu yopereka ma elekitironi ya gulu la para-methoxy, p-methoxybenzaldehyde imakhudzidwa ndi allyltrimethylsilane pansi pa catalysis ya bismuth trifluorosulfonate kuti ipeze mankhwala opangidwa ndi diallylated.
