Maitiro Ekugadzira Formic Acid

Asidhi yeFormic imusanganiswa weorganic une fomura yemakemikari inonzi HCOOH. Inogona kugadzirwa nenzira dzakasiyana-siyana, dzinosanganisira methanol oxidation, carbon monoxide-water reduction, uye gas-phase processes.

Nzira yeMethanol Oxidation

Nzira yekuoxidation yemethanol ndeimwe yenzira dzinoshandiswa zvakanyanya muindasitiri pakugadzira formic acid. Mafambiro enzira iyi ndeaya anotevera:

(1) Kugadzirira Zvinhu Zvisina Kugadzirwa:
Methanol nemhepo zvinogadzirwa sezvinhu zvitsva. Methanol inocheneswa uye inorasikirwa nemvura mumuviri kuti ivandudze mashandiro emuviri.

(2) Maitiro eCatalytic Oxidation:
Methanol inosangana neokisijeni pasi pemamiriro chaiwo ekupisa uye kumanikidzwa, kazhinji ichishandisa chinhu chinobatsira chesimbi. Methanol inotanga yasanganiswa kuita formaldehyde, iyo inozosanganiswazve kuita formic acid.

(3) Kuparadzana uye Kucheneswa:
Zvigadzirwa zvereaction zvinoparadzaniswa uye zvinocheneswa, kazhinji kuburikidza nekudistillation kana crystallization.

(4) Kurapa Gasi Remuswe:
Izvi zvinogadzira magasi emuswe ane CO2, CO2, N2, nezvimwe zvinhu, izvo zvinoda kurapwa nenzira dzekunyudza, kuomesa, kana kuchenesa.

Mutengo wakaderedzwa we formic acid kubva muna Nyamavhuvhu kusvika Gumiguru, tinya pano kuti uiwane.
