Kev Tshawb Fawb Txog Propionic Acid Infrared (IR)
Siv lub tshuab ntsuas infrared spectrometer los nrhiav. Piv txwv li, yog xav paub txog propionic acid thiab lwm yam tshuaj zoo sib xws, muab me me ntawm cov qauv propionic acid rau ntawm potassium bromide pellet lossis siv txoj kev ua kua los npaj cov qauv kuaj uas tsim nyog. Tom qab ntawd muab cov qauv tso rau hauv lub cell qauv ntawm lub tshuab ntsuas infrared spectrometer. Lub tshuab ntsuas infrared spectrometer tso tawm lub teeb infrared. Thaum lub teeb infrared ci rau cov qauv, cov qauv molecules nqus cov zaus tshwj xeeb ntawm lub teeb infrared, ua rau muaj kev hloov pauv ntawm lub zog vibrational thiab rotational. Cov tshuaj sib txawv nqus cov zaus sib txawv ntawm lub teeb infrared, ua rau muaj cov yam ntxwv ntawm kev nqus peaks hauv lub spectrum infrared. Propionic acid muaj cov pab pawg ua haujlwm xws li carboxylic acid, uas qhia txog cov yam ntxwv ntawm kev nqus peaks hauv lub spectrum infrared (piv txwv li, qhov ncab vibration peak ntawm pawg carboxylic acid yog nyob ib ncig ntawm 1700 cm⁻¹). Los ntawm kev sib piv cov spectrum tau txais nrog cov qauv infrared spectrum ntawm cov propionic acid paub, nws tuaj yeem txiav txim siab seb cov qauv puas yog propionic acid. Ib qho kev kwv yees txog cov ntsiab lus ntawm propionic acid kuj tseem tuaj yeem ua tau raws li qhov muaj zog ntawm cov ncov tshwj xeeb, tab sis txoj kev no feem ntau siv rau kev tshuaj xyuas zoo.info@pulisichem.cn

Shandong Pulisi Chemical Co., Ltd. muaj Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— ib qho carboxylic acid luv luv uas muaj ntau yam kev ntshiab nrog 99.5% min purity, tau los ntawm thiab tsim tawm hauv tsev rau kev muab khoom ruaj khov thiab taug qab. Peb cov propionic acid yog cov kua ntshiab, pungent nrog kev tiv thaiv zoo tiv thaiv pwm thiab cov kab mob, ntseeg tau dav dav ua cov khoom siv tiv thaiv qib pub, cov khoom noj khoom haus qib pwm inhibitor, thiab tseem ceeb nruab nrab rau kev pleev xim, tshuaj, thiab kev tsim tshuaj txhua hnub. Peb kho cov qib thiab ntim khoom: 200kg yas nruas, 1000kg IBC totes, lossis ISO tanks, nrog rau cov ntaub ntawv tag nrho (COA, MSDS, ISO, HALAL) kom ua tau raws li kev ua raws li thoob ntiaj teb. Nrog ntau xyoo ntawm kev paub txog kev xa khoom tawm, peb xa cov khoom zoo sib xws, tus nqi sib tw, thiab kev xa khoom txhim khu kev qha — koj tus khub mus rau rau kev txiav txim propionic acid thoob ntiaj teb.
