Propanamide yog dab tsi?
Xi'an Faithful BioTech Co., Ltd. tau koom tes nrog kev tsim khoom thiab muag cov khoom zoo nruab nrab rau ntau xyoo, thiab tuaj yeem ruaj khov muab cov khoom sib txawv ntawm cov purities sib txawv. Tom qab ntau cov txheej txheem purification thiab rov ntim dua, cov khoom raug muag hauv ntau rau kev tshawb fawb tshuaj lom neeg thiab tshuaj lom neeg hauv ntau lub tebchaws thoob ntiaj teb. Leveraging nws paub tab ntshuam thiab export kev lag luam kev paub thiab warehousing thiab tis muaj peev xwm, lub tuam txhab muaj peev xwm ua tau raws li cov kev xav tau ntawm ob qho tib si me me -batch scientific research samples thiab loj - ntim kev lag luam xaj. Kev tso siab rau kev daws teeb meem kev lag luam kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom xa tuaj, thiab nrog nws cov khoom ruaj khov zoo, nws tau dhau los ua kev koom tes txhim khu kev qha rau cov neeg siv khoom hauv tsev thiab thoob ntiaj teb ntawm propanamide.Propanamide, CAS Tsis yog . 79-05-0, molecular mis C3H7NO, yog ib qho tshuaj zoo raw khoom ntawm aliphatic thawj amide nrog cov qauv ntawm cov pa roj carbon monoxide thiab ib qho hnyav molecular ntawm 73.09. Nyob rau hauv chav tsev kub, nws yog ib tug dawb crystalline khoom nrog ib tug tsis muaj zog yam ntxwv amide tsw. Nws cov ntsiab lus melting yog li ntawm 79℃mus rau 83 degree, thiab nws qhov kub ntawm qhov kub siab yog 213 degree. Nws nthuav tawm zoo heev physicochemical stability thiab tsis yooj yim hydrolyze spontaneously nyob rau hauv ib txwm cia tej yam kev mob. Hydrolysis tsuas yog tshwm sim nyob rau hauv muaj zog acid, muaj zog alkali, los yog sab nraud cua sov tej yam kev mob, decomposing mus rau hauv propionic acid thiab ammonia{10}}muaj derivatives.
Propanamide Manufacturing txheej txheem
Los ntawm qhov kev xav ntawm hluavtaws, txoj kev npaj ua lag luam tseem ceeb nyob ntawm qhov siab -kub amidation thiab lub cev qhuav dej ntawm propionic acid thiab siab - purity ammonia. Xwb, nws tuaj yeem ua kom huv los ntawm ammonolysis ntawm propionyl chloride. Cov khoom siv raw tuaj yeem rov ua dua tshiab los ntawm ethanol kom tau txais qib siab -purity tiav cov khoom. Tag nrho cov txheej txheem ntau lawm yog paub tab thiab tswj tau, haum rau loj- nplai ntau lawm. Cov tshuaj no yog ib qho tseem ceeb ntawm cov khoom siv hluavtaws nruab nrab hauv kev lag luam tshuaj zoo, nrog rau kev siv ntau yam xws li agrochemicals, cov ntaub ntawv polymer tshiab, biochemical tshawb fawb reagents, thiab cov khoom siv tshuaj txhua hnub.Propanamidetuaj yeem siv los ua cov khoom siv raw rau kev sib txuas ntxiv ntawm propylamine, nitrile derivatives, thiab amide auxiliaries, thiab tseem tuaj yeem siv los ua cov muab tub lim hloov hauv kev hloov kho thiab ua cov khoom siv polymer. Tsis tas li ntawd, nws ua haujlwm raws li tus qauv siv substrate rau kev tshawb fawb hauv cov txheej txheem tshuaj tiv thaiv ntawm amide-raws li cov organic compounds. Nrog nws cov khoom sib npaug ntawm hydrophilic thiab lipophilic, nws txuas ntxiv nthuav dav nws qhov chaw thov hauv kev tsim cov koom haum tshwj xeeb.

Mechanism ntawm kev txiav txim ntawm Propionamide
Tshuaj Reaction Intermediates: Carbonyl Nucleophilic Ntxiv thiab tshem tawm
Cov pab pawg carbonyl carbon yog electron- tsis txaus, nkag mus ntxiv thiab tshem tawm cov tshuaj tiv thaiv nrog nucleophiles. Nws yog siv nyob rau hauv lub synthesis ntawm alkylamines, hloov amides, thiab zoo tshuaj derivatives, thiab yog ib tug tseem ceeb lub tsev thaiv nyob rau hauv lub synthesis ntawm propyl series tshuaj.
Biochemical Enzyme Activity Assay Substrate
Nrog nws cov qauv yooj yim thiab tsis tu ncua, nws yog siv hauv kev sim hauv vitro los ntsuas cov haujlwm ntawm amide hydrolases thiab kawm txog biochemical transformation ntawm amide compounds.
Coordination Chelation Extraction
Cov pa carbonyl oxygen thiab amino nitrogen pawg muaj ib leeg khub ntawm electrons, uas tuaj yeem ua rau ntau yam hlau cations. Nws ua hauj lwm pab raws li ib tug hlau extraction pab nyob rau hauv hydrometallurgy thiab tshuaj sib cais.
