Rau cov organic synthesis, kuj siv los ua ib qho reagent thiab roj chromatography nyob ruaj ruaj rau kev txiav txim siab ntawm mercury
Nws muaj peev xwm kho cov tshuaj tsw qab. Nws tuaj yeem siv tau me me hauv nruab nrab thiab qib qis txhua hnub, tshwj xeeb tshaj yog nyob rau hauv xab npum essence nrog nws cov ntxhiab tsw zoo li geranium. Nws tuaj yeem siv rau hauv tib neeg sawv, nyom tshiab, geranium thiab ntau hom tshuaj, thiab nws kuj tuaj yeem siv los tsim cov roj geranium. Nws tuaj yeem sib koom tes thiab sib tov zoo nrog dimethyl hydroquinone, coumarin thiab hydroxycitronellal, thiab tuaj yeem koom tes nrog cov txiv hmab txiv ntoo xws li txiv duaj thiab rubus.
Nws yog siv los ua ib qho nruab nrab hauv cov organic synthesis thiab hauv kev tsim cov diphenhydramine hydrochloride hauv kev lag luam kws tshuaj. Diphenylmethane tuaj yeem siv los hloov cov roj geranium, haum rau kev npaj ntawm xab npum essence thiab naj hoom. Kuj tseem siv rau hauv kev tsim cov xim.
