Wan wamoko tamwa me miini wel ma opore, jami maber atika, ki bene cwalo oyot bot luyub me China cato 99.5% Propionic Acid CAS 79-09-4 ki wel me Factory, kare weny, wabedo ka keto cwinywa i kom jami weny me neno ni jami weng ma ki yubu ni oyomo cwiny luwil wa.
Wan wamoko tamwa me miini wel ma opore, jami maber ma ber, ki bene kelo jami oyot, cik pa kampuni wa tye ni "rwom mukwongo, me bedo maber ki tek, dongo ma rii". Gin ma wamito tye "pi lwak, luwil, lutic, lutic luwot ki kampuni me nongo adwogi maber". Wa mito tic kacel ki dano ma gi yubu jami me motoka, ka yubu jami, dano ma gi yubu motoka, ki dong yubu anyim maber! Wapwoyo pi kwanyo kare me neno kabedowa me Intanet dok wabi jolo tam mo keken ma itwero bedo kwede ma twero konyowa me yubo kabedowa me Intanet.
Kwedo kit ma ki yubu kwede Propionic Acid Chemical Formula
Me aa ki i neno pa jami ma ki lwongo ni molecule, rwom me propionic acid ma ki lwongo ni CH₃CH₂COOH ki twero poko ne i dul adek. Dul ma ki lwongo ni terminal methyl group (CH3–) nyutu kit ma ki lwongo ni saturated alkyl, dul me methylene ma i kine (–CH₂–) tiyo calo gin ma kubbe, ki dul ma ki lwongo ni carboxyl group (–COOH) miyo molecule ni kit ma en tye kwede. Kit ma ki yubu kwede ni nyutu ni propionic acid nyutu jami mogo ma calo alkane ki kit ma carboxylic acid tiyo kwede.
I kom kabedo, gin ma ki lwongo ni propionic acid molecule ni tye ki kit ma ki yubu kwede ma yot. C=O double bond ki –OH hydroxyl group i carboxyl group ni gi yubu coplanar structure, kun alkyl chain ni gi tiyo ki tetrahedral geometry kun wok ki i sp3 hybridization. Kit ma ki yubu kwede ni miyo molecule ni polarity ma rwate, ma nyutu kit ma en twero rubu kwede ki pii kun nongo tye ka gwoko rwate ki non-polar solvents calo diethyl ether ki chloroform.
Ki ngeyo, carboxyl hydrogen ma tye i propionic acid poko ne i pii, ma weko H+ ions ki yubu propionate anions (CH₃CH₂COO⁻). poko man kelo pKa me 4.87 (i 25°C), ma poko ne calo acid ma goro. Kit ma acid-base ni tye kwede pire tek pi tic mapol, tutwale calo gin ma gwoko cam, ma kit ma kome ma pe ki poko twero donyo kwede i cell pa kwidi two.
