Propionic Acid National Standard (GB Specifications)
Propionic acid caah ram pumpi phunglam nih a muisam kha fiang tein a fianter: rong a ngei lomi, a fiangmi ti a si lai i rim a nam lai, cun a rong nih a hleiin hmuh khawhmi rong tahfung (tahchunhnak ah, APHA man nih a khiahmi ri a lonh lomi) kha a tlinh a hau, cu nih cun thilri nih a muisam tthatnak a herhmi kha a tlinh khawh lai.
Thianhlimnak kongah, ram pumpi phunglam nih a tlawmbik propionic acid 99.0% a ngeih a fial. Hi thianhlimnak sang a herhnak nih propionic acid nih riantuannak le hmannak thil sining phunphun ah fekmi le zumhawktlakmi riantuannak a pek khawhnak hnga a bawmh. Ti tlawmtam cu thilri tthatnak a hnorsuanmi a biapi tukmi thil pakhat a si; phunglam ningin, ti tlawmtam cu 0.5% tang ah uk a hau, cu nih cun a tam tukmi ti nih a chemical sining le riantuan ning a hnahnawhnak hnga lo. Acidity, a biapi bikmi langhtertu pakhat in, fiang tein a langhter ve: acidity (mass fraction in langhtermi, propionic acid in tuakmi) cu thilri chemical fekmi le thlennak nih a herhmi a tlinh khawh nakhnga a fiangmi tlukruannak chungah a tla a hau. Thir rit a ummi cu phunglam ah fek tein rikhiah a si—hri, mercury, le a dang thir rit pawl cu a niam tukmi tluk in rikhiah an si, a tlangpi in ppm (million pakhat ah tthen) in tah a si, rawl, sii sernak le a dang a biapimi riantuannak ah hman khawhnak ding caah.
Ram pumpi phunglam nih a tlawm le tam kongah a dikthliar in a herhmi zong a chiah. A hleiin lumnak (tahchunhnak ah, 20°C) ah, a ritmi cu a khiahmi chung ah a tla a hau, cu nih cun thilri sining nih phunglam he aa tlak le tlak lo a langhter. A lum khawhnak cu a biapi tukmi ruah awk dang pakhat a si: propionic acid cu a tlangpi in 140°C – 142°C tiang a lum khawhnak a ngeih a hau, cu nih cun a lum le a tthawnnak kha aa tlakmi riantuannak nih a herhmi a tlinter. Chloride dat cu fek tein uk a si, thilri tthatnak le a hnu riantuannak ah a chiatnak lei in hnahnawhnak a chuahter lonak ding caah chloride dat cu a hleiin a tlawmbik (tahchunhnak ah, 0.001%) tang ah um a herh. Thir dat zong a fiangmi rikhiahnak tangah a um, a tlangpi in 0.0001% nak tam lo, thir thilri nih propionic acid rong, fek tein um khawhnak le riantuan ning a hnorsuan khawhnak hnga lo.
A cawh khawhnak kong he pehtlai in, ram pumpi phunglam nih propionic acid cu a hleiin a cawh khawhnak (tahchunhnak ah, ethanol, diethyl ether) ah a cawh khawhnak ttha langhter a herh, cu nih cun hmannak thil sining phunphun ah sernak herhmi tlinter awkah ratio cheukhat ah cawh khawhnak tling a pek.
Shandong Pulisi Chemical Co., Ltd. cu Tuluk ram ah a ttha ngaimi riantuannak-tlukmi propionic acid sertu le zuartu a si, vawleicung riantuannak ah a ttha ngaimi a thianghlimmi, zumhawktlakmi thilri le aa tlakmi thilri pawl pekchanhnak ah aa pemi a si. Kan propionic acid cu a fekmi GB/T 10615 phunglam tangah chuahmi a si, a ttha bikmi thianhlimnak cu ≥99.5% a phan i a hmasa bik a ttha mi cu ≥99.0% a si, a tlawmmi ti, a tlawmmi thir a tlawmmi, le a phunphun in hmanmi thilri hna i a herhmi thilri pawl tlinter awkah a tlawmmi thir tlawmtam a ngeimi a si.
A tthangchomi propylene oxidation thiamnak hmangin sermi, kan propionic acid nih a fekmi chemical sining, a ttha ngaimi a cawh khawhnak, le a ttha tein aa khatmi a tthatnak a pek. Organic sernak, plastic sernak, electroplating tuahnak, rawl le rawl kilvennak, le sii le agrochemical chuahnak ah a biapi mi karlak ah rian a ttuan. Kan innchung thilri tthatnak zohfelnak laboratory le a tlingmi hneksaknak phunglam hna nih a bawmhmi, phorhmi paoh cu vawleicung pumpi ah tluang tein luhternak le hmannak caah COA, MSDS, le a dang zulhphung cazin hna he aa pehtlaimi a si.
Asia, Europe, Middle East le a lenglei ah kum tampi chung kuatnak hmuhtonnak he, a fawimi thilri chiahnak thimnak, zuamnak man, le FOB, CIF, le DDP telh in zumhawktlak kuatnak caan kan pek hna. Hneksaknak order hmete na herh zongah siseh, thilri tampi na herh zongah siseh, kan i pekchanhmi phu cu na chawlehnak herhmi a dang tein tlinter awkah a ttha mi thiamnak lei bawmhnak le na duh ning in tuahmi riantuannak pek awkah timhcia an si.
