Cov tshuaj tiv thaiv ntawm ib qho amine thiab formaldehyde ua raws li kev txo qis amination tuaj yeem tsim ib qho tshuaj methylated amine. Ib qho tertiary amine feem ntau yog cov khoom ntawm cov tshuaj tiv thaiv yog tias siv formaldehyde ntau dhau. Cov txheej txheem rau kev sib txuas yog tib yam li saum toj no.
Yam khoom twg koj xav kom tau txais los ntawm kev txo qis ntawm aldehyde siv NH3 ?
Qhov ncaj qha txo qis amination ntawm carbonyl tebchaw nrog NH3 thiab H2 yog lwm txoj hauv kev los tsim primary amines hauv kev tsim tawm.
Tus neeg sawv cev txo qis hauv kev txo qis yog dab tsi?
Sodium triacetoxyborohydride yog ib qho dav dav, me me, thiab xaiv txo tus neeg sawv cev rau kev txo qis ntawm ntau yam aldehydes thiab ketones. 1, 2-Dichloroethane (DCE) yog qhov nyiam cov tshuaj tiv thaiv hnyav, tab sis cov tshuaj tiv thaiv kuj tuaj yeem nqa tawm hauv tetrahydrofuran thiab qee zaus hauv acetonitrile.
Yuav ua li cas thiaj txo tau amination?
Kev txo qis yuav suav nrog tus txheej txheem ib-lossis ob-kauj ruam uas muaj amine thiab carbonyl compound condense kom them tau ib qho imine lossis iminium ion uas txo qis hauv qhov chaw lossis tom qab tsim cov khoom lag luam amine.
Amination yog dab tsi?
Amination yog txheej txheem uas ib pawg amine tau nkag mus rau hauv cov organic molecule. … Hom tshuaj tiv thaiv no yog ib qho tseem ceeb vim hais tias organonitrogen tebchaw yogpervasive.
