Gbɛjianɔtoi ni akɛfeɔ Formic Acid

Formic acid ji tsofa ko ni yɔɔ wala mli ni tsofa ni ji HCOOH yɔɔ mli. Abaanyɛ atsɔ gbɛi srɔtoi anɔ afee, ni nɔ ni fata he ji methanol oksideshin, carbon monoxide-nu ni baa shi, kɛ gas-fase gbɛjianɔtoi.

Methanol Oksidashin Gbɛ

Methanol oxidation gbɛ lɛ ji nitsumɔhei ni akɛtsuɔ nii babaoo kɛfeɔ formic acid lɛ ateŋ ekome. Gbɛjianɔtoo lɛ ji bɔ ni nyiɛ sɛɛ nɛɛ:

(1) Nibii ni Akɛtsuɔ Nii He Saamɔ:
Afee methanol kɛ kɔɔyɔɔ akɛ nibii ni akɛtsuɔ nii. Methanol lɛ tsɔɔ hetsemɔ kɛ nu ni sɛɛ tsɛɔ mli koni ekɛha nɔ ni etsuɔ ​​lɛ aya hiɛ.

(2) Katalitik Oksidashin Hetoo:
Methanol kɛ kɔɔyɔɔ ni haa wala yibii tsuɔ nii yɛ dɔlɛ kɛ nɔnyɛɛ shihilɛi pɔtɛɛ komɛi amli, ni akɛ dade ni haa kɔɔyɔɔ lɛ tsuɔ nii. Klɛŋklɛŋ lɛ, tsofa ni ji methanol lɛ feɔ formaldehyde, ni no sɛɛ lɛ, ehaa tsofa lɛ feɔ formic acid.

(3) Mligbalamɔ kɛ Hetsemɔ:
Ajara nibii ni jɛɔ mli baa lɛ amli ni atsuuɔ amɛhe, bei pii lɛ kɛtsɔ distillation loo kristalization nɔ.

(4) Tail Gas Tsamɔ:
Nɔ ni jɛɔ mli baa lɛ haa kɔɔyɔɔ ni yɔɔ CO, CO2, N2, kɛ nibii krokomɛi amli lɛ baa, ni biɔ ni atsu he nii kɛtsɔ gbɛi ni atsɔɔ nɔ aŋɔɔ, agbiɔ, loo atsuuɔ he lɛ nɔ.

Formic acid jara ni aba shi kɛjɛ August kɛyashi October, nyɛɛ biɛ koni onine ashɛ nɔ.
