Oxalic Acid Carbohydrate Oxidation Lam
Hi lam nih hin changvut le changvut pawl kha thilri ah a hman hna i 73-80 °C ah nitric acid in a cawh hna i oxalic acid a chuahter. Tahchunhnak ah starch lak ahcun, a kalning cu a tanglei bantuk in a si: 85% mass fraction starch cu 10% oxalic acid asiloah a dang thilri hna i an nu zu aa telmi ti chung ah an cawh, acid in an lumter, cun a karlak thilri glucose hmuh hmasa awkah suimilam 6 chung an thlen. Cun, nitric acid le thir-vanadium catalyst cu 63 °C ah hydrolysis tuahnak caah an chap, cun oxalic acid cu thlennak hnu ah thianhnak in hmuh a si.
A biapi bikmi thil sining cu starch kha glucose ah a thlen, cu hnuah nitric acid he oxalic acid ah aa thlen
Fe 3+ le V2O5V
catalysts. Hi lam nih hin fawi tein hmuh khawhmi thilri, a fawimi kalning, a nemmi riantuannak dirhmun, le tangka luhternak a tlawmmi a langhter, cun ram hna nih anmah le an thilri dirhmun ning in thilri phunphun an i thim khawh. Thlaici chuahnak le sipuazi tthatnak kongah, buh hnah cu a tlangpi in thimnak tha bik a si. Sihmanhsehlaw, a chiatnak hna cu a tlawmmi cinmi, rawl tampi hmanmi, chuah man a fakmi, le a hnulei gas ah nitrogen oxides tampi a ummi, cu hna cu a thurhnawmmi an si i pawngkam thurhnawmhnak fakpi an chuahter.

Shandong Pulisi Chemical cu 99.6% a tlawm bik thianhlimnak he a thianghlimmi industry-grade oxalic acid (dihydrate, H2C2O4·2H2O) a sertu le a zuartu Tuluk thiamsang a si.
