Propionic Acid Nuclear Magnetic Resonance (NMR) Spectroscopy
Gwiritsani ntchito spectrometer ya nyukiliya ya maginito kuti mupeze propionic acid. Potengera kusanthula kwa kapangidwe ka propionic acid mu mankhwala opangidwa ndi mankhwala monga chitsanzo, choyamba konzani chitsanzocho kukhala yankho loyenera, nthawi zambiri pogwiritsa ntchito ma reagents ochotsedwa monga deuterated chloroform kuti mupewe kusokonezedwa ndi solvent peak pa peak ya chitsanzo. Ikani chubu cha NMR chokhala ndi yankho la chitsanzo mu probe ya NMR spectrometer. Chidacho chimatulutsa ma radiofrequency pulses kuti chipangitse kusintha kwa mphamvu ya nyukiliya mu maatomu a mamolekyu a chitsanzo. Nuclei m'malo osiyanasiyana a mankhwala imatenga ndi kutulutsa zizindikiro za radiofrequency mosiyana, zomwe zimapangitsa kuti pakhale ma peak osiyana mu NMR spectrum. Mwa kusanthula chilengedwe cha mankhwala cha atomu iliyonse ya hydrogen mu molekyulu ya propionic acid, pamodzi ndi chidziwitso monga malo oyambira (chemical shift) ndi kugawanika kwa peak (coupling constant), kapangidwe ka propionic acid kangatsimikizidwe. Kusanthula kwa kuchuluka kwa zomwe zili mkati mwake kungathenso kuchitidwa pamlingo winawake. Komabe, NMR spectroscopy nthawi zambiri si yolondola kwambiri pa kusanthula kwa kuchuluka poyerekeza ndi njira zina, koma imapereka ubwino wapadera pa kusanthula kwa kapangidwe kake.

Shandong Pulisi Chemical Propionic Acid    info@pulisichem.cn
Shandong Pulisi Chemical imapereka propionic acid yapamwamba CAS 79-09-4 yokhala ndi chiyero mpaka 99.5%. Kuwongolera mwamphamvu kuipitsidwa kumatsimikizira magwiridwe antchito okhazikika a zosungira chakudya, zowonjezera chakudya, kugwiritsa ntchito zinthu zopangira mankhwala pakati ndi mafakitale.
Tili ndi malo osungiramo katundu odziyimira pawokha komanso unyolo wokhazikika woperekera katundu, womwe umathandizira kulongedza zinthu mosavuta, malo okwanira opezeka komanso kutumiza zinthu mwachangu padziko lonse lapansi. Gulu lililonse limabwera ndi COA ndi MSDS yonse, ndi kuwunika kolimba kwabwino kuti zitsimikizire kuti zinthuzo zimagwirizana bwino. Utumiki waukadaulo wotumiza katundu ku China umatipangitsa kukhala ogulitsa propionic acid odalirika kwa nthawi yayitali.
