I-Propionic Acid Infrared (IR) Spectroscopy
Sebenzisa i-infrared spectrometer ukuthola. Uma uthatha ukuhlonza i-propionic acid kanye nezinye izinto ezifanayo njengesibonelo, faka inani elincane lesampula ye-propionic acid ku-potassium bromide pellet noma usebenzise indlela yefilimu yoketshezi ukulungiselela isampula yokuhlola efanelekile. Bese ubeka isampula kuseli lesampula le-infrared spectrometer. I-infrared spectrometer ikhipha ukukhanya kwe-infrared. Lapho ukukhanya kwe-infrared kukhanyisa isampula, ama-molecule esampula amunca amaza athile okukhanya kwe-infrared, okubangela ukuguquka kwezinga lamandla okudlidliza nokujikeleza. Izibopho zamakhemikhali ezahlukene zimunca amaza ahlukene okukhanya kwe-infrared, okuholela eziqongweni zokumunca ezihlukile ku-infrared spectrum. I-Propionic acid iqukethe amaqembu asebenzayo njenge-carboxylic acid, abonisa amaza okudonsa ahlukile ahambisanayo ku-infrared spectrum (isb., ukuphakama kokudlidliza okunwebekayo kweqembu le-carboxylic acid cishe ku-1700 cm⁻¹). Ngokuqhathanisa i-spectrum etholiwe ne-standard infrared spectrum ye-propionic acid eyaziwayo, kunganqunywa ukuthi isampula iyi-propionic acid. Ukulinganisa okulinganiselwe kokuqukethwe kwe-propionic acid kungenziwa futhi ngokusekelwe ekuqineni kweziqongo zesici, kodwa le ndlela ngokuvamile isetshenziswa kakhulu ekuhlaziyweni kwekhwalithi.info@pulisichem.cn

I-Shandong Pulisi Chemical Co., Ltd. inikeza i-Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— i-carboxylic acid enezinhlanganisela eziningi enokuhlanzeka okungu-99.5% min, etholakala futhi ekhiqizwa ngaphakathi ukuze itholakale ngokuqhubekayo nangokulandeleka. I-propionic acid yethu iwuketshezi olucacile, olunobuthi olunokuvimbela okunamandla isikhunta namabhaktheriya, oluthembeke kakhulu njengesivikelo sezinga lokuphakelayo, isithibi sezinga lokuphakelayo, kanye nesihluthulelo esibalulekile sokumboza, imithi, kanye nokuhlanganiswa kwamakhemikhali kwansuku zonke. Sihlela amazinga kanye nokupakishwa: amadramu epulasitiki angu-200kg, ama-tote e-IBC angu-1000kg, noma amathangi e-ISO, anemibhalo ephelele (i-COA, i-MSDS, i-ISO, i-HALAL) ukuze kuhlangatshezwane nokuhambisana komhlaba wonke. Njengoba sineminyaka eminingi yesipiliyoni sokuthumela kwamanye amazwe, sinikeza ikhwalithi ehambisanayo, amanani okuncintisana, kanye ne-logistics ethembekile — umlingani wakho ohamba naye wama-oda e-propionic acid amaningi emhlabeni jikelele.
