I-Propionic Acid Nuclear Magnetic Resonance (NMR) Spectroscopy
Sebenzisa i-nuclear magnetic resonance spectrometer ukuthola i-propionic acid. Uma uthatha ukuhlaziywa kwesakhiwo se-propionic acid emikhiqizweni yokwenziwa kwamakhemikhali njengesibonelo, qala ngokulungiselela isampula ibe yisisombululo sokuhlushwa okufanele, ngokuvamile usebenzisa ama-reagents ahlutshiwe njenge-deuterated chloroform ukugwema ukuphazamiseka okuvela esicongweni se-solvent esicongweni sesampula. Beka ithubhu le-NMR eliqukethe isisombululo sesampula ku-probe ye-NMR spectrometer. Ithuluzi likhipha ama-radiofrequency pulses ukuze libangele ukuguquka kwezinga lamandla enuzi kuma-athomu ama-molecule esampula. Ama-Nuclei ezindaweni ezahlukene zamakhemikhali amunca futhi akhiphe izimpawu ze-radiofrequency ngendlela ehlukile, okuholela eziqongweni ezihlukile ku-spectrum ye-NMR. Ngokuhlaziya indawo yamakhemikhali ye-athomu ngayinye ye-hydrogen ku-molecule ye-propionic acid, kanye nolwazi olufana nendawo ye-peak (ukushintsha kwamakhemikhali) kanye nokuhlukaniswa kwe-peak (ukuhlangana okuhambisanayo), isakhiwo se-propionic acid singaqinisekiswa. Ukuhlaziywa kwe-quantitative kokuqukethwe kwayo kungenziwa futhi ngezinga elithile. Kodwa-ke, i-NMR spectroscopy ngokuvamile ayiqondile kangako ekuhlaziyweni kwe-quantitative uma kuqhathaniswa nezinye izindlela, kodwa inikeza izinzuzo ezihlukile zokuhlaziywa kwesakhiwo.

I-Shandong Pulisi Chemical inikeza i-premium propionic acid CAS 79-09-4 ngobumsulwa obufika ku-99.5%. Ukulawulwa okuqinile kokungcola kuqinisekisa ukusebenza okuzinzile kokulondolozwa kokudla, okungeziwe kokudla, ukusetshenziswa kwezinto zokusetshenziswa kwamakhemikhali eziphakathi nendawo kanye nezimboni.
Sinezindawo zokugcina impahla ezizimele kanye nochungechunge lokunikezela oluzinzile oluphezulu, olusekela ukupakishwa okuguquguqukayo, isitokwe esanele kanye nokulethwa okusheshayo emhlabeni jikelele. Iqoqo ngalinye liza ne-COA ephelele kanye ne-MSDS, kanye nokuhlolwa kwekhwalithi okuqinile ukuqinisekisa ukuhambisana kweqoqo okuzinzile. Insizakalo yobuchwepheshe yokuthumela ngaphandle okukodwa isenza sibe ngumhlinzeki wakho we-propionic acid othembekile wesikhathi eside ovela eShayina.
