npaj
Kev npaj ntawm aminoguanidine hydrochloride: 9 g ntawm aminoguanidine carbonate tau muab tso rau hauv 250ml peb qhov chaw nres nkoj, 20ml ntawm meej txog ethanol tau ntxiv, cov khoom tau insoluble hauv anhydrous ethanol los tsim kev ncua. Raws li nplawm nyob rau ntawm chav tsev kub, qhov sib xyaw ntawm 6ml 30% concentrated hydrochloric acid thiab 10ml ntawm cov ethanol raug tso tawm ntxiv kom txog thaum tsis muaj npuas, thiab tom qab ntawd nplawm cov tshuaj tiv thaiv tau txuas ntxiv hauv chav tsev li 1 teev. Qhov muab ncua tau rhuab kom yaj cov khoom kom tiav, thiab tom qab ntawd nws yog qhov ib txwm qis rau chav sov. Tom qab tau hloov mus rau hauv lub tub yees thiab muab tso rau thaum hmo ntuj, cov pas nrig dawb zoo li tus siv lead ua nrog kev xav txog ntawm 166-167℃ tau txais.
Thov
Daidzein muaj ntau yam kev nyab xeeb ntawm kev siv tshuaj, tiv thaiv thiab kho ntau yam kab mob. Cn200910144204.1 tshaj tawm tias aminoguanidine hydrochloride tuaj yeem siv los npaj cov tshuaj daidzein hloov kho, suav, daidzein 7,4 '- oxygen aminoguanidine acetate. Cov kua qaub aglycone 7,4 '- oxygen aminoguanidine acetate yog cov tshuaj tiv thaiv kab mob, uas tso cov tshuaj niam txiv - daidzein raws li lub cev kev mob, thiab txhim kho nws cov dej solubility los ntawm covalent khi
Kev npaj ntawm Daidzein 7,4 ' - o-aminoguanidine acetate: 0.5g aminoguanidine hydrochloride tau ploj nyob rau hauv 100ml acetone, 0.02g theem hloov catalyst, 0.5g anhydrous potassium carbonate, 0.5g 7,4 ' - chloroacetyl daidzein thiab 0.02g I2 tau ntxiv rau hauv qhov kev daws teeb meem. Qhov tshuaj tiv thaiv tau nqa ntawm chav tsev li 24 teev. Acetone tau lim dej los ntawm cov lim dej hauv qab kom txo qis, thiab tom qab ntawd cais los ntawm silica gel kem. Tus eluent tau ethyl acetate∶ Petroleum ether Thaum piv yog 1 ∶ 2, Cov hmoov dawb dawb tau txaisCov.
