In-situ ongororo yezvigadzirwa zvisina kugadzikana uye online spectral yekutarisa yave nzira dzekutsvaga chete
Mune imwe nitration reaction, asidhi yakasimba senge nitric acid inoda kushandiswa kunitrate mbishi kugadzira zvigadzirwa zve nitration.Iyo nitration chigadzirwa chekuita uku haina kugadzikana uye inoora nyore.Kuti uwane chigadzirwa chakanangwa, kuita kwese kunoda kuitwa munzvimbo ye -60 ° C.Kana nzira dzekunze dzemurabhoritari dzakadai sechromatography, mass spectrometry, uye nyukireya magineti resonance ikashandiswa kuongorora chigadzirwa, chigadzirwa chinogona kuora panguva yekuongorora uye ruzivo rwakakwana nezvemabatiro hahugone kuwanikwa.Uchishandisa online spectroscopy tekinoroji ye-in-situ chaiyo-nguva yekutarisa, iyo yemukati mutsauko wechigadzirwa uye kufambira mberi kwekuita kunojeka pakungotarisa.Muchidzidzo chemaitiro akadai ane zvinhu zvisina kugadzikana, tekinoroji yekutarisa pamhepo ndiyo chete nzira inoshanda yekutsvagisa.
Mufananidzo uri pamusoro unorekodha chaiyo-nguva yepamhepo yekutarisisa yeiyo nitrification reaction.Hunhu hwepamusoro hwechigadzirwa panzvimbo 954 uye 1076 cm-1ratidza maitiro akajeka ekusimudzira uye kuderera nekufamba kwenguva, izvo zvinoratidza kuti yakarebesa kuita nguva inotungamira mukuparara kwezvigadzirwa zve nitration.Nekune rimwe divi, nzvimbo yepamusoro yehunhu hwepamusoro inoratidza iyo chigadzirwa chiri muhurongwa.Kubva pane data rekutarisa repamhepo, zvinogona kuoneka kuti zvirimo zvechigadzirwa ndizvo zvakanyanyisa kana maitiro asvika kumaminitsi makumi mana, zvichiratidza kuti maminetsi makumi mana ndiwo akanyanya kuita.
