I-Propionic Acid Infrared (IR) Spectroscopy
Sebenzisa i-infrared spectrometer ukuze ufumane. Ukuthatha umzekelo wokuchongwa kwe-propionic acid kunye nezinye izinto ezifanayo, sebenzisa inani elincinci lesampuli ye-propionic acid kwi-potassium bromide pellet okanye usebenzise indlela yefilimu yolwelo ukulungiselela isampuli efanelekileyo yovavanyo. Emva koko beka isampuli kwiseli yesampuli ye-infrared spectrometer. I-infrared spectrometer ikhupha ukukhanya kwe-infrared. Xa ukukhanya kwe-infrared kukhanyisa isampuli, iimolekyuli zesampuli zifunxa ii-frequency ezithile zokukhanya kwe-infrared, nto leyo ebangela utshintsho lwamandla okushukuma kunye nokujikeleza. Iibhondi ezahlukeneyo zeekhemikhali zifunxa ii-frequency ezahlukeneyo zokukhanya kwe-infrared, nto leyo ebangela ii-peaks zokufunxa eziphawulekayo kwi-infrared spectrum. I-Propionic acid iqulethe amaqela asebenzayo afana ne-carboxylic acid, ebonisa ii-peaks zokufunxa ezihambelanayo kwi-infrared spectrum (umz., i-peak yokungcangcazela eyolukileyo yeqela le-carboxylic acid imalunga ne-1700 cm⁻¹). Ngokuthelekisa i-spectrum efunyenweyo kunye ne-standard infrared spectrum ye-propionic acid eyaziwayo, kunokugqitywa ukuba isampuli yi-propionic acid. Uqikelelo oluqikelelweyo lomxholo we-propionic acid lunokwenziwa ngokusekelwe kubunzulu beencopho zeempawu, kodwa le ndlela idla ngokusetyenziswa kakhulu kuhlalutyo lomgangatho.info@pulisichem.cn

I-Shandong Pulisi Chemical Co., Ltd. inikezela nge-Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— yi-asidi ye-carboxylic emfutshane enobunyulu obuyi-99.5%, efumaneka kwaye yenziwe ngaphakathi ukuze ifumaneke ngokuzinzileyo nangokulandelelekayo. I-asidi yethu ye-propionic lulwelo olucacileyo, olunobukrakra olunokuthintela okunamandla ukungunda kunye neebhaktheriya, oluthembeke kakhulu njengesigcini-mveliso esikumgangatho wokutya, isithinteli-sikhunta esikumgangatho wokutya, kunye nesiphambili sokudibanisa, amayeza, kunye nokuhlanganiswa kweekhemikhali zemihla ngemihla. Silungisa amanqanaba kunye nokupakisha: iidrama zeplastiki ezingama-200kg, iitoti ze-IBC ezingama-1000kg, okanye iitanki ze-ISO, kunye namaxwebhu apheleleyo (i-COA, i-MSDS, i-ISO, i-HALAL) ukuhlangabezana nokuthobela kwehlabathi. Ngamava eminyaka yokuthumela ngaphandle, sinikezela ngomgangatho ohambelanayo, amaxabiso akhuphisanayo, kunye ne-logistics ethembekileyo — iqabane lakho eliya ku-odola i-asidi ye-propionic eninzi kwihlabathi liphela.
