Oxalic Acid thilri zohfelnak
Oxalic acid, ethanedioic acid tiah auhmi zong cu, a sawhsawh bikmi dicarboxylic acid a si i a molecule formula (COOH) 2 ⋅2H2O
A rong a ngei lomi columnar crystals bantuk in a lang i herbaceous thingram hna ah a tlangpi in a ummi thil pakhat a si, a tam deuh cu potassium asiloah calcium chiti bantuk in a um, cu lio ah Chinese crabapple le banana tibantuk thingram hna ah cun free acid bantuk in hmuh a si. Minung zun ah oxalic acid tlawmpal zong a um, cun calcium oxalate cu zunthlum lung a chuahtertu a si. 100.1 °C tiang lumter tikah, oxalic acid crystals nih an crystallization ti an sungh i ti a ngei lomi oxalic acid an ser, cu cu 189.5 °C a linnak hmun a si. Ti a ngei lomi oxalic acid cu ti asiloah ethanol ah a cawh khawh nain ether ah a cawh khawh lo. Laboratory ah, oxalic acid cu lumternak in carbon monoxide gas chuah khawh a si.
Oxalic acid cu hmannak phunphun a ngeimi a biapi tukmi chemical thilri a si i rian tampi ah hman a si. Sii sernak, rong, le thilthuam sernak riantuannak a tthancho i ramkip chawlehnak a hun tikah, oxalic acid chuahnak kong hlathlainak le tthanchoter a herh ngaingai.

Shandong Pulisi Chemical Co., Ltd. – Oxalic Acid Profile
Shandong Pulisi Chemical Co., Ltd., October 2006 ah dirhmi le Zibo, Shandong ah zungpi a ngeimi, vawleicung pumpi ah a ttha ngaimi chemical thilri a chuahtu thiamsang hruaitu a si. "A ttha mi chemical sernak ah lungthin peknak" timi ruahnak ah aa pemi, company cu R&D, chuahnak, zuarnak le thilri kuatnak aa fonhmi a tlingmi riantuannak ah aa thleng, Zibo Anhao Chemical Co., Ltd. le China Changrui Co., Limited telh in aa pehtlaimi bu hna he.
Kan oxalic acid (CAS No.: ti a ngei lomi caah 144-62-7, ti a tlawmmi caah 6153-56-6) cu a hrampi thilri a si, vawleicung tthatnak phunglam ningin sermi a si. Industrial grade (a thiangmi ≥96%) le a thiangmi grade (a thiangmi ≥99.6%) pahnih in hmuh khawh a si, kan oxalic acid cu rong a ngei lomi a fiangmi crystals (a tlangpi in dihydrate) in a um i molecule formula C2H2O₄·2H₂O le molecule ritnak 1267 a si. Ti le ethanol ah a cawh khawhnak a sang, a zorter khawhnak a tthawng, cun a tthawngmi acidity a ngei—cu nih cun a tthawng bikmi organic dicarboxylic acid pakhat ah a ser.
ISO 9001:2015 phunglam he aa tlakmi le German BV bantuk nawlngeitu bu hna nih an fehtermi, kan oxalic acid cu riantuannak phunphun ah hman a si:
Thir sernak: Thir, dar le a dang thir hna caah ttha tein vutcam hlohnak, thir thianhnak le complexation agent.
Saknak: Concrete cawhmi le inn saknak thilri sernak caah a biapimi thilri.
Savun sernak: Savun rangternak, hriak hlonhnak le vun rangternak caah hmanmi a si.
Ti thianhnak: Ti tthatnak tthanchoternak le hnah hlohnak caah Chelating agent.
Thilpuan le cauk chuahnak: A rangternak sii le rong thlennak bawmtu.
Sii sernak le rawlchuannak: Sii sernak ah hmanmi thilri le rawlchuannak thilri sernak ah hman a si.
Qingdao, Tianjin, Shanghai tilawng dinhnak le Zibo Free Trade Zone ah aa hngatmi thil chiahnak inn hna he, vawleicung mipi sin ah ttha tein phorh khawhnak kan tuah. Kan thilri pawl cu REACH, FAMI-QS le SGS hnatlaknak an tei cang, cun Europe, America, Southeast Asia, Middle East le Central Asia ram le pengtlang 100 leng ah kuat an si. PetroChina, CNOOC, Saint-Gobain le Lafarge telh in minthang company hna he caan saupi a fekmi riantuan ttinak pehtlaihnak kan ser.
Shandong Pulisi Chemical ah, vawleicung pumpi ah a phunphun in riantuannak herhmi hna tlinternak caah a tthatnak, himnak le riantuannak ah aa hngatmi riantuannak kha biapi ah kan chiah.
