Chigadzirwa molecular chimiro:
Oxalic acid inoparadzirwa zvakanyanya muchirimwa mune zvakasikwa, yakawanda iripo muchimiro che oxalic acid munyu.CW Scheele yaive kekutanga kugadzira oxalate muna 1776.
Oxalate ndiyo yakasimba asidhi pakati pe dicarboxylic acid.Kunze kwekuve neyakajairwa zvimiro zvecarboxylic acid, ine zvakare inodzikisira midziyo uye inogona kuderedza zvakanyanya iwo manomwe valence manganese kuita bivalent manganese.Ichi chivako chinowanzoshandiswa pachiyero chekuongorora potassium permanganate.
5 C2H2O4 + 2 KMnO4 + 3 H2SO4 →K2SO4 + 2 MNSO4 + 8H2O + 10 CO2;
Oxalic acid inogona zvakare kuderedza iyo trivalent iron kuita bivalent iron.Pamusana pekunyungudika kwepamusoro kwesimbi ye bivalent mumvura, tinogona kushandisa iyi nheyo kubvisa ngura pazvipfeko.
Oxalic acid inogona kuita nephosphorus pentachloride kugadzira phosphorus oxychloride.C2H2O4 + PCl5 → POCl3 + CO + CO2 + 2 HCL.
Oxalic acid inogona kuita nesimbi zhinji kugadzira oxalic acid munyu.Pamusoro peiyo alkali simbi munyu uye bivalent iron munyu pamwe neimwe oxalic acid munyu isinganyungudika mumvura.Imwe simbi munyu, kunyangwe isinganyungudika mumvura, inogona kugadzira yakaoma inonyungudika mumvura.
Fe2 (C2O4) 3 + 3 K2C2O4 + 6 H2O →2 K3 [Fe (C2O4) 3] • 6 H2O.
Pakupisa, alkali simbi uye alkaline pasi simbi oxalic acid munyu inogona kurasikirwa nekabhoni monoxide uye kugadzira carbonates ine carbonate inoramba ichiiswa pasi pekudziisa kuti iwedzere kuora kuita oxide necarbon dioxide.Iyo oxalic acid munyu we nickel, cobalt uye sirivheri inogona pakupedzisira kugadzira simbi pachinzvimbo chenonmetal oxide.
Zvigadzirwa zvinoora zveoxalate icarbon dioxide, carbon monoxide nemvura.
Oxalate uye oxalic acid munyu zvine chepfu.Mice, kuburikidza nemuromo wekutonga, ine LD50 ye2000 ~ 4000 mg / kg.
1. Oxalic acid inogona kunyanya kushandiswa seanoderedza ajenti uye bleaching agent, mordant yekudhaya uye kudhinda indasitiri, inoshandiswawo mukunatsa isingawanzo simbi, kuumbwa kweakasiyana oxalate ester amide, oxalate uye uswa, nezvimwe.
2. Inoshandiswa seanalytical reagent.
3. Inoshandiswa sema laboratory reagents, chromatography yekuongorora reagent, dhayi yepakati uye yakajairwa zvinhu.
4. Oxalic acid inonyanya kushandiswa kugadzira mishonga yakadai semishonga inorwisa mabhakitiriya neborneol uye zvinonyungudutsa pakubvisa simbi isingawanzoitiki, inoderedza agent uye dhayi, tanning agent, nezvimwewo. Pamusoro pezvo, oxalic acid inogonawo kushandiswa kugadzira marudzi akasiyana-siyana eoxalate. ester, oxalate, uye oxamide ine diethyl oxalate, sodium oxalate uye calcium oxalate ine goho guru.Oxalate inogona zvakare kushandiswa kugadzira cobalt-molybdenum-alumina catalyst, kuchenesa simbi uye marble pamwe nekucheneswa kwemachira.
Chemwin inogona kupa huwandu hwakawanda hwemahydrocarbon akawanda uye makemikari zvinonyungudutsa kune vatengi vemaindasitiri.Izvi zvisati zvaitika, ndapota verenga zvinotevera ruzivo rwekuita bhizinesi nesu:
1. Chengetedzo
Chengetedzo ndiyo inonyanya kukosha kwatiri.Pamusoro pekupa vatengi ruzivo nezve mashandisiro akachengeteka uye ane hushamwari ezvigadzirwa zvedu, isu takazvipirawo kuona kuti njodzi dzekuchengetedza dzevashandi nemakondirakiti dzadzikiswa kuita shoma inonzwisisika uye inogoneka.Naizvozvo, isu tinoda kuti mutengi ave nechokwadi chekuti kurodha kwakakodzera uye kuchengetedza kuchengetedza zviyero zvinosangana tisati tasvitsa (ndapota tarisa kune HSSE appendix muhuwandu hwematemu uye mamiriro ekutengesa pazasi).Nyanzvi dzedu dzeHSSE dzinogona kupa gwara pane aya mazinga.
2. Delivery nzira
Vatengi vanogona kuraira uye kuendesa zvigadzirwa kubva kuchemwin, kana kuti vanogona kugamuchira zvigadzirwa kubva kune yedu kugadzira chirimwa.Nzira dziripo dzekutakura dzinosanganisira rori, njanji kana multimodal kutakura (zvakasiyana mamiriro anoshanda).
Panyaya yezvinodiwa nevatengi, tinogona kutsanangura zvinodikanwa zvemabhaji kana matangi uye kushandisa yakakosha kuchengetedza / kuongorora zviyero uye zvinodiwa.
3. Minimum order yakawanda
Kana iwe ukatenga zvigadzirwa kubva pawebhusaiti yedu, iyo yakaderera odha huwandu i30 matani.
4.Payment
Iyo yakajairika nzira yekubhadhara inobviswa zvakananga mukati memazuva makumi matatu kubva painvoice.
5. Delivery zvinyorwa
Mapepa anotevera anopiwa kune imwe neimwe yekutumira:
· Bill of Lading, CMR Waybill kana rimwe gwaro rekufambisa rakakodzera
· Sitifiketi Yekuongorora kana Conformity (kana zvichidikanwa)
· Zvinyorwa zvine chekuita neHSSE zvinoenderana nemitemo
· Zvinyorwa zvetsika zvinoenderana nemirairo (kana zvichidikanwa)
