Kuyeza kwa Propionic Acid Infrared (IR) Spectroscopy
Gwiritsani ntchito infrared spectrometer kuti muzindikire. Potengera kuzindikira propionic acid ndi mankhwala ena ofanana, ikani chitsanzo chochepa cha propionic acid pa potassium bromide pellet kapena gwiritsani ntchito njira yamadzimadzi yopangira chitsanzo choyenera. Kenako ikani chitsanzocho mu selo lachitsanzo la infrared spectrometer. Infrared spectrometer imatulutsa kuwala kwa infrared. Pamene kuwala kwa infrared kumawunikira chitsanzocho, mamolekyu a chitsanzocho amayamwa ma frequency enaake a kuwala kwa infrared, zomwe zimapangitsa kusintha kwa mphamvu yamagetsi ndi yozungulira. Ma bond osiyanasiyana a mankhwala amayamwa ma frequency osiyanasiyana a kuwala kwa infrared, zomwe zimapangitsa kuti ma absorption ayambe bwino mu infrared spectrum. Propionic acid ili ndi magulu ogwira ntchito monga carboxylic acid, omwe amasonyeza ma absorption angwiro ofanana mu infrared spectrum (monga, stretching vibration peak ya gulu la carboxylic acid ndi pafupifupi 1700 cm⁻¹). Poyerekeza spectrum yomwe yapezeka ndi standard infrared spectrum ya propionic acid yodziwika bwino, zitha kudziwika ngati chitsanzocho ndi propionic acid. Kuyerekeza koyerekeza kwa kuchuluka kwa propionic acid kungathenso kupangidwa kutengera mphamvu ya nsonga za khalidwe, koma njira iyi nthawi zambiri imagwiritsidwa ntchito kwambiri pofufuza za khalidwe.info@pulisichem.cn

Shandong Pulisi Chemical Co., Ltd. imapereka Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— asidi wa carboxylic wokhala ndi unyolo wochepa wokhala ndi ukhondo wa mphindi 99.5, wopangidwa mkati kuti ukhale wokhazikika komanso wosavuta kutsatira. Propionic acid yathu ndi madzi omveka bwino, onunkhira bwino komanso oletsa kwambiri bowa ndi mabakiteriya, odalirika kwambiri ngati chosungira chakudya, choletsa bowa cha chakudya, komanso chofunikira kwambiri pakuphimba, mankhwala, komanso kupanga mankhwala tsiku ndi tsiku. Timasintha magiredi ndi ma phukusi: 200kg pulasitiki ng'oma, 1000kg IBC totes, kapena matanki a ISO, okhala ndi zikalata zonse (COA, MSDS, ISO, HALAL) kuti akwaniritse malamulo apadziko lonse lapansi. Ndi zaka zambiri zokumana nazo zotumiza kunja, timapereka khalidwe lokhazikika, mitengo yopikisana, komanso njira zodalirika zoyendetsera zinthu — mnzanu woyenera kuyitanitsa propionic acid wambiri padziko lonse lapansi.
