Ndlela ya Glyoxal Oxidation ya Oxalic Acid

Ndlela ya Glyoxal Oxidation ya Oxalic Acid
Glyoxal yina reducibility yo tiya, hikokwalaho yinga hatlisa yi oxidized kuya eka oxalic acid ehansi ka xiendlo xa strong oxidizing nitric acid. Hikokwalaho ka swilo swofana na mphakelo wa switirhisiwa swoka swinga tirhisiwanga, nxavo, na thekinoloji, ndlela leyi ayi phikizana kahle eka makete naswona ayi endliwanga eka ti indasitiri.
Ku engetela kwalaho, ku ni tindlela tin’wana to endla oxalic acid:
(1) Ndlela yo lunghiselela khaboni-dayokisayidi: Khaboni-dayokisayidi yi rhanga yi hungutiwa yi va leyi nga exikarhi
CO2
ivi endzhaku yi hundzuriwa swilo swin’wana leswi hanyaka. Oxalic acid yi kumiwa hi ku voninga tisisiteme to hambana-hambana ta khaboni-dayokisayidi hi tindlela ta tikhemikhali ta gezi ni mavoni ya γ-ray, ku vonakala ka dyambu kumbe mavoni ya mercury ya ntshikelelo lowukulu.
(2) Ndlela yo n’okisela alkali hiku tirhisa switirhisiwa leswi fuweke hi cellulose: Nkatsakanyo wa switirhisiwa leswi fuweke hi cellulose (kufana na tihunyi letinga thyaka, chaff, na swin’wana) na inorganic strong alkali swi n’okisiwa swin’we eka 513–558 K kuva swihumelerisa kutlula 50% wa oxalate. Ti crystals ta oxalate ti khuluka hiku crystallization, kutani kutirhisiwa sulphuric acid kuva ku kumiwa oxalic acid leyi hetiweke. Endlelo leri rina endlelo ro olova ro lulamisa oxalic acid, kambe single-pass conversion rate yile hansi (ehansi ka 35%), ku tirhisiwa ka alkali swile henhla, naswona ku thyakisa mbango swikulu swinene.
(3) Ndlela yo humelerisa malahla ya switirhisiwa swo ka swi nga tirhisiwanga: Yi lulamisiwa kusuka eka ti peats to hambana hambana tani hi switirhisiwa swo ka swi nga tirhisiwanga. Xikombiso, oxalic acid yi humelerisiwa kusuka eka peat ya genera ya Sphagnum na Polytrichum hiku tirhisa nitric acid oxidation. Ku cinca cinca ku endliwa eka 343 K kuringana 8–9 wa tiawara, laha kungana mbuyelo wofika eka 95%. Loko switirhisiwa swoka swinga lulamisiwanga swofana na coal tar switirhisiwa ku humelerisa oxalic acid, mbuyelo na wona wufika eka 51%.

Shandong Pulisi Chemical Co., Ltd. – Mutivi wa Asidi ya Oxalic (Asidi ya Ethanedioic).

Shandong Pulisi Chemical, muendli wa tikhemikhali loyi a rhangelaka loyi a simekiweke hi 2006 e Zibo, China, u tiveka ngopfu eka vuhumelerisi bya oxalic acid ya vutengi bya le henhla na mphakelo wa misava hinkwayo. Layini ya hina ya swikumiwa swa core oxalic acid yi kombisa giredi ya indasitiri (99.6% min ku basa) na giredi ya swakudya (99.8% min ku basa) tinxaka, leti kumekaka eka swivumbeko swa dihydrate (H2C2O4·2H2O, CAS 6153-56-6) na anhydrous (H2C4O4, CAS 144-62-7) ku hlangana swilaveko swo hambana swa tiindasitiri.

Yi endliwe hi thekinoloji ya vuhumelerisi bya xiyimo xale henhla xikan’we na vulawuri byo tika bya khwalithi lebyi fambelanaka na swipimelo swa ISO 9001:2015, oxalic acid ya hina yikombisa ti levele tale hansi ta thyaka—sulfate ≤0.07%, tinsimbi to tika (Pb) ≤0.0005%, na iron (Fe) ≤0.0005%—ku tiyisisa ku tshembheka eka switirhisiwa kusuka eka ku basisiwa ka tinsimbi na ku tshungula dzovo kuya eka ku basisiwa ka mati na ku lulamisiwa ka swakudya. Hi khoma switifikheti leswi nga na vulawuri ku katsa na ku landzelela ka REACH na ku tsarisiwa ka FAMI-QS, ku tiyisisa ku namarhela ka hina eka mimpimanyeto ya vuhlayiseki na khwalithi ya matiko ya misava.

Yi pakiwile eka swikhwama swa PP leswi lukiweke swa 25kg (leswi nga cinciwaka hi ku kandziyisiwa ka logo) eka tioda ta vunyingi bya tiindasitiri, oxalic acid ya hina yi kumeka eka ku rhumeriwa ka FOB ku suka eka swikepe swa Qingdao, Tianjin, kumbe Shanghai. Hi vuswikoti bya vuhumelerisi bya n’hweti na n’hweti bya 3,000 wa tithani na ntlawa wa R&D lowu tinyiketeleke, hi nyika swintshuxo leswi lulamisiweke: tioda ta swiphemu leswitsongo, ku paka loku endleriweke wena, na nseketelo wa xithekiniki eka tiphurojeke leti kongomisiweke eka tiklayenti. Tanihi muphakeri loyi a tshembiwaka eka matiko yo tlula 30, hi rhangisa emahlweni vutleketli lebyi nga enkarhini na vuhlanganisi lebyi nga erivaleni, leswi hi endlaka hi va nhlawulo lowu tsakeriwaka eka ku xava ka oxalic acid ya misava hinkwayo.
