    Taupānga

    1. Koia te mea kakara nui i roto i te puawai Hawthorn, putirā me te hā lilac.

    2. Ka whakamahia hei kakara kakara i te rengarenga o te raorao.

    3. Ka whakamahia hei whakarereke i te Osmanthus fragrans.

    4. Ka taea hoki te whakamahi i nga mea reka o ia ra, me nga kai reka.

    Taonga

    He wairewa i roto i te waiwaro, wairewa i roto i te ethyl ether, benzene me etahi atu whakarewa pararopi, he wairewa ano ki te wai.

    Rokiroki

    Whakaorangia ki te wahi maroke, marumaru, whai hau.

    Te pumau

    1. Ko te hau me te hau he ranunga pahū. Whakamaua nga karaehe whakamarumaru, kakahu whakamarumaru, me nga karapu tiaki.

    2. Kei roto i nga rau tupeka me te auahi.

    3. Kei roto i nga hinu tino nui penei i te hinu anise whetu, te hinu kumine, te hinu anise whetu, te hinu pi, te hinu acacia, me te hinu witi.

    4. Kaore i te tino pumau ki te marama, he ngawari ki te oxidize me te huri i te tae o te rangi ki te whakaputa waikawa anisic.

    5. Ka taea te whakamahi p-Methoxybenzaldehyde ki te tiaki i nga diols, dithiols, amines, hydroxylamines me te diamines.

    Ko te whakamarumaru o te diol p-methoxybenzaldehyde ka ngawari te hanga e te hohenga o te diol me te aldehyde ki te hanga acetal. Ko te whakakōkī ka taea te waikawa pūhaumāota konutea pūhaumāota ranei, ranei te tahi atu tikanga pērā i iodine catalysis me polyaniline rite te kaikawe waikawa Sulfuric catalysis, indium trichloride catalysis, bismuth pākawa pūhaumāota, me ētahi atu P-methoxybenzaldehyde tauhohe ki L-cysteine ​​​​ki te whiwhi thiazole pärönaki.

    Te tauhohenga me nga roopu amino Ka taea e te P-methoxybenzaldehyde te tauhohe me nga roopu amino hei hanga i nga turanga Schiff, ka whakahekehia e NaBH4 hei hanga amine tuarua.

    Ko te hanga o te ethylene oxide pärönaki p-methoxybenzaldehyde ka taea te tauhohe ki te ylides whanariki ki te hanga pärönaki ethylene oxide, a ka taea hoki te tauhohe ki te pūhui diazonium ki te whiwhi i taua pärönaki. Ka taea hoki e te tauhohenga me nga pärönaki ethylene oxide te whakawhänui i te whakakai ki te whiwhi pärönaki mowhiti furan.

    Tauhohenga Diacylation I raro i te catalysis o te tetrabutylammonium bromide (TBATB), ka taea e p-methoxybenzaldehyde te tauhohe me te waikawa anhydride ki te hanga i nga hua diacylation.

    I roto i te tauhohenga allylation, na te kaha koha irahiko o te roopu para-methoxy, ka tauhohe te p-methoxybenzaldehyde me te allyltrimethylsilane i raro i te catalysis o te bismuth trifluorosulfonate ki te whiwhi i te hua waea.
