Kulanga-langa zintu zya Oxalic Acid
Oxalic acid, alimwi wiitwa kuti ethanedioic acid, ni dicarboxylic acid iitakatazyi kapati iijisi foomu ya molecule (COOH) 2 ⋅2H2O
Chilibonya mbuli mabwe aatakwe mubala mpawo nchintu chidumide muzisyango, bunji bwaziindi zili muchikozyano cha potassium naa calcium salts, mpawo chijanika mbuli asidi iitakwe mubala muzisyango zilimbuli Chinese crabapple a banana. Kabeela kaniini ka oxalic acid alajanika mumulota wamuntu, mpawo calcium oxalate ngomulongo mupati wamabwe aamunzila yaminsyu. Eelyo nozipya kusika ku 100.1 °C, mabwe aa oxalic acid alasweekelwa maanzi aakupanga ma oxalic acid aatakwe maanzi, alo aajisi busena bwakunyenguluka bwa 189.5 °C. Oxalic acid iitakwe maanzi ilakonzya kunywika mumaanzi naa ethanol pesi tayinyonyooki mu ether. Mu laboratory, oxalic acid ilakonzya kubola akupya kuti izwe muya uutegwa carbon monoxide.
Oxalic acid nchintu chiyandikana loko chakubelesya mumisela myiingi alimwi chibelesyegwa mumbazu zyiingi. Kakuli kuyaambele kwamakwebo aamisamu, idayi, azyakuvwumba akujalulwa kwamusika wanyika yoonse, nchintu chipati loko kuvwuntauzya akusumpula kupanga oxalic acid.

Shandong Pulisi Chemical Co., Ltd. – Oxalic Acid Profile
Shandong Pulisi Chemical Co., Ltd., yakatalisyigwa mu mwezi wa Nalupale 2006 mpo ilaa munzi mupati ku Zibo, Shandong, ninkamu iisololela mukusambala zintu zyamakemikalu zyaatala kapati alimwi ilaa mulimo munyika yoonse. Kakulipeda kumuzeezo wa "kubikkila maanu kukusumpuka kwamakemikalu mabotu", inkamu yakasanduka kuba kkampani iijisi zyoonse ziswaanganya R&D, kupanga, kusambazya akutola zintu, antoomwe amakkampani aajatikizyidwe mbuli Zibo Anhao Chemical Co., Ltd. antoomwe a China Changrui Co., Limited.
Asidi yesu ya oxalic (CAS No.: 144-62-7 ya anhydrate, 6153-56-6 ya dihydrate) nchintu chipati, chakapangwa kuti chizuzikizye zyeelelo zyanyika yoonse. Zilajanwa muzibeela zyoonse zyobile (kusalala ≥96%) azyakusalazya (kusalala ≥99.6%), oxalic acid yesu iliwo mbuli mabwe aasalala aatakwe mubala (kanjikanji dihydrate) a fomuyula ya molecule C₂H₂O₄·2H₂O abulemu bwa molecule bwa 127.00. Chili aanguzu zyakunyonyooka mumaanzi amu ethanol, chikonzya kucesya nguzu, antoomwe aasidi mpati—zipa kuti ibe akati kama dicarboxylic acids aanguzu kapati.
Kakuli kweendelezyegwa kabotu kuti kweendelane azyeelelo zya ISO 9001:2015 alimwi akuzumizigwa ambunga zijisi nguzu mbuli German BV, oxalic acid yesu ilabelesyegwa kapati mumakkampani miingi:
Busongo bwabutale: Kugwisya nsimbi, kusalazya nsimbi antoomwe akupa kuti butale, mukuba azimwi nsimbi zibe zikatazya kumvwisisisya.
Kuyaka: Zibelesyo zipati zyakubelesya kusanganya konkriti akubamba zintu zyakuyasya.
Makwebo aachikumba: Abelesyegwa kusanzya, kugwisya mafuta akusanzya chikumba.
Kusalazya maanzi: Chelating agent yakusumpula bubotu bwamaanzi akugwisya zilonda.
Zisani akusimba: Chibelesyo chakusanzya azyakudaya.
Mafakitali aamisamu azyakulya: Abelesyegwa mukupanga misamu iili akati-kati alimwi akupanga zintu ziyungizyidwe muzyakulya.
Kakuli maanda aakulida aalikke mu Qingdao, Tianjin, Shanghai alimwi a Zibo Free Trade Zone, tulasinizya kuti zintu zyatuminwa kabotu kuli basikuula banyika yoonse. Zintu zyesu zyakainda mu REACH, FAMI-QS antoomwe a SGS, mpawo zilatumwa kuzisi ziinda ku 100 mu Europe, America, Southeast Asia, Middle East antoomwe a Central Asia. Twakabamba chilongwe chiyumu chakubeleka antoomwe amakkampani aazyibidwe mbuli PetroChina, CNOOC, Saint-Gobain antoomwe a Lafarge.
Ku Shandong Pulisi Chemical, tulabikkila maanu kububotu, lukwabililo akugwasya basikuula, kupa nzila zya oxalic acid zigwasya bantu baindene-indene nyika yoonse mbwiizulwa.
