Maendlelo ya Vuhumelerisi bya Formic Acid

Formic acid i nkatsakanyo wa organic lowu nga na fomula ya tikhemikhali ya HCOOH. Yinga endliwa hiku tirhisa tindlela to hambana hambana, kukatsa na methanol oxidation, carbon monoxide-water reduction, na maendlelo ya gas-phase.

Ndlela ya Oxidation ya Methanol

Ndlela ya methanol oxidation i yin’wana ya maendlelo ya ti indasitiri lawa ya tirhisiwaka ngopfu eka vuhumelerisi bya formic acid. Ku khuluka ka phurosese hi ndlela leyi landzelaka:

(1) Ku Lunghiselela Switirhisiwa Swo Karhi: .
Methanol na moya swi lulamisiwa tani hi switirhisiwa swoka swinga tirhisiwanga. Methanol yi hundza eka ku basisiwa na ku susiwa ka mati ku antswisa ku tirha kahle ka reaction.

(2) Nhlamulo ya Oxidation ya Catalytic:
Methanol yi endla reaction na oxygen ehansi ka swiyimo swokarhi swa mahiselo na ntshikelelo, hi ntolovelo yi tirhisa catalyst ya nsimbi. Methanol yisungula ku oxidized kuva formaldehyde, leyi yaka emahlweni yi oxidized kuva formic acid.

(3) Ku Hluvukisa Ni Ku Basisa:
Switirhisiwa swa reaction swa hambanisiwa naku basisiwa, hi xitalo hiku tirhisa distillation kumbe crystallization.

(4) Vutshunguri bya Gasi ya Micila:
Ku cinca loku ku humesa tigasi ta ncila letingana CO, CO2, N2, na swiphemu swin’wana, leswi lavaka vutshunguri hiku tirhisa tindlela to tswonga, ku omisa kumbe ku basisa.

Ntsengo lowu hungutiweke wa formic acid ku sukela hi August ku ya eka October, tinya laha ku yi kuma.
