Propionic Acid Nuclear Magnetic Resonance (NMR) Spectroscopy
Shandisa nuclear magnetic resonance spectrometer kuti uone propionic acid. Uchitora ongororo yepropionic acid structure mumakemikari synthesis products semuenzaniso, tanga wagadzirira sampuro yacho kuita solution yakakodzera, kazhinji uchishandisa deuterated reagents dzakadai se deuterated chloroform kudzivirira kukanganiswa kubva pa solvent peak pa sample peak. Isa chubhu yeNMR ine sample solution mu probe yeNMR spectrometer. Chishandiso ichi chinoburitsa radiofrequency pulses kuti chikonzere shanduko yesimba renyukireya mumaatomu ema sampuli molecules. Nuclei munzvimbo dzakasiyana dzemakemikari inonwisa uye inoburitsa ma radiofrequency signals zvakasiyana, zvichikonzera peaks dzakasiyana muNMR spectrum. Nekuongorora chemical environment ye hydrogen atomu yega yega mu propionic acid molecule, pamwe chete neruzivo rwakadai se peak position (chemical shift) uye peak splitting (coupling constant), chimiro chepropionic acid chinogona kusimbiswa. Kuongororwa kwehuwandu hwezviri mukati mayo kunogonawo kuitwa kusvika pamwero wakati. Zvisinei, NMR spectroscopy kazhinji haina kunyatsojeka pakuongorora kwehuwandu kana ichienzaniswa nedzimwe nzira, asi inopa mabhenefiti akasiyana ekuongorora kwechimiro.

Shandong Pulisi Chemical Propionic Acid    info@pulisichem.cn
Shandong Pulisi Chemical inopa premium propionic acid CAS 79-09-4 ine kuchena kusvika ku99.5%. Kudzora kusvibiswa kwakasimba kunoita kuti pave nekushanda kwakasimba kwekuchengetedza chikafu, kuwedzerwa kwezvekudya, kushandiswa kwemakemikari pakati nepakati uye zvinhu zvemaindasitiri.
Tine matura epachiteshi akazvimiririra uye cheni yekugovera zvinhu yakagadzikana, ichitsigira kurongedza kunochinjika, nzvimbo yakakwana uye kutumirwa nekukurumidza pasi rose. Batch yega yega inouya neCOA yakazara neMSDS, ine kuongororwa kwakasimba kwemhando kuti ive nechokwadi chekuti batch inowirirana. Basa rehunyanzvi rekutumira zvinhu kunze kwenyika rimwe chete rinoita kuti tive mutengesi wako wenguva refu wepropionic acid kubva kuChina.
