    Daim ntawv thov

    1. Nws yog cov txuj lom tseem ceeb hauv Hawthorn paj, paj noob hlis thiab lilac tsw.

    2. Nws yog siv los ua tshuaj tsw qab nyob rau hauv lily ntawm hav.

    3. Nws yog siv los hloov kho hauv Osmanthus fragrans.

    4. Nws kuj tseem siv tau rau txhua hnub flavors thiab zaub mov flavors.

    Khoom

    Nws yog soluble hauv ethanol, soluble hauv ethyl ether, benzene thiab lwm yam organic solvents, kuj soluble hauv dej.

    Cia

    Khaws rau ntawm qhov chaw qhuav, shady, ventilated.

    Kev ruaj ntseg

    1. Nws cov pa roj thiab cua tsim ib qho kev sib xyaw tawg. Hnav looj tsom iav, khaub ncaws tiv thaiv, thiab hnab looj tes tiv thaiv.

    2. Muaj nyob rau hauv cov nplooj thiab cov pa luam yeeb.

    3. Nws ib txwm muaj nyob rau hauv cov roj yam tseem ceeb xws li lub hnub qub anise roj, cumin roj, lub hnub qub anise roj, dill roj, acacia roj, thiab pob kws roj.

    4. Nws tsis ruaj khov rau lub teeb, nws yooj yim rau oxidize thiab hloov xim hauv huab cua los tsim cov anisic acid.

    5. p-Methoxybenzaldehyde tuaj yeem siv los tiv thaiv diols, dithiols, amines, hydroxylamines thiab diamines.

    Diol tiv thaiv p-methoxybenzaldehyde tuaj yeem yooj yim tsim los ntawm cov tshuaj tiv thaiv ntawm diol thiab aldehyde los ua acetal. Cov catalyst siv tuaj yeem yog hydrochloric acid lossis zinc chloride, lossis lwm txoj hauv kev xws li iodine catalysis thiab polyaniline raws li cov cab kuj Sulfuric acid catalysis, indium trichloride catalysis, bismuth nitrate catalysis, thiab lwm yam. P-methoxybenzaldehyde reacts nrog L-cysteine ​​​​tau thiazole. derivatives.

    Cov tshuaj tiv thaiv nrog cov amino pawg P-methoxybenzaldehyde tuaj yeem hnov ​​​​mob nrog cov amino pawg los tsim Schiff bases, uas raug txo los ntawm NaBH4 los tsim cov amines theem nrab.

    Tsim cov ethylene oxide derivatives p-methoxybenzaldehyde tuaj yeem hnov ​​​​mob nrog sulfur ylides los ua ethylene oxide derivatives, thiab tuaj yeem ua rau cov tshuaj diazonium kom tau cov khoom zoo li no. Cov tshuaj tiv thaiv nrog ethylene oxide derivatives kuj tseem tuaj yeem nthuav lub nplhaib kom tau txais furan nplhaib derivatives.

    Cov tshuaj tiv thaiv diacylation Raws li catalysis ntawm tetrabutylammonium bromide (TBATB), p-methoxybenzaldehyde tuaj yeem ua rau cov kua qaub anhydride los tsim cov khoom diacylation.

    Hauv cov tshuaj tiv thaiv kev sib raug zoo, vim muaj zog electron pub dawb ntawm pawg para-methoxy, p-methoxybenzaldehyde reacts nrog allyltrimethylsilane nyob rau hauv lub catalysis ntawm bismuth trifluorosulfonate kom tau cov khoom diallylated.
