Usoro Mmepụta nke Formic Acid

Asịd Formic bụ ihe mejupụtara organic nke nwere usoro kemịkalụ HCOOH. Enwere ike imepụta ya site na ụzọ dị iche iche, gụnyere oxidation methanol, mbelata mmiri carbon monoxide, na usoro gas-phase.

Usoro Oxidation Methanol

Usoro methanol oxidation bụ otu n'ime usoro mmepụta ihe kachasị eji eme ihe maka mmepụta formic acid. Usoro usoro a bụ dịka ndị a:

(1) Nkwadebe Ihe Ndị A Na-anaghị Arụpụta:
A na-akwadebe methanol na ikuku dị ka ihe eji emepụta ihe. A na-eme ka methanol dị ọcha ma na-akpọnwụ akpọnwụ iji mee ka mmeghachi omume dịkwuo mma.

(2) Mmeghachi omume Oxidation nke Catalytic:
Methanol na-emeghachi omume na oxygen n'okpuru ọnọdụ okpomọkụ na nrụgide pụrụ iche, na-ejikarị ihe na-akpalite ígwè. A na-ebu ụzọ mee ka methanol bụrụ formaldehyde, nke a na-eme ka ọ bụrụ formic acid.

(3) Nkewa na Nchacha:
A na-ekewa ma sachaa ngwaahịa mmeghachi omume ahụ, a na-ejikarị ya eme ihe site na distillation ma ọ bụ crystallization.

(4) Ọgwụgwọ Gas Ọdụ:
Mmeghachi omume ahụ na-emepụta gas ọdụ nwere CO, CO₂, N₂, na ihe ndị ọzọ, nke chọrọ ọgwụgwọ site na iji usoro ịmịkọrọ, ịkpọ nkụ, ma ọ bụ nhicha.

Ọnụ ego e belatara maka formic acid site na Ọgọst ruo Ọktoba, pịa ebe a iji nweta ya.
