Njira Yoyezera Mpweya wa Formic Acid
Njira yogwiritsira ntchito gas-phase ndi njira yatsopano kwambiri yopangira formic acid. Kayendedwe ka ndondomekoyi ndi motere:
(1) Kukonzekera Zinthu Zopangira:
Methanol ndi mpweya zimakonzedwa, ndipo methanol imayeretsedwa ndi kutayidwa madzi m'thupi.
(2) Kuyankha kwa Oxidation ya Gas-Phase:
Methanol yokonzedwa kale imagwirizana ndi mpweya pamene pali chothandizira, zomwe zimapangitsa formaldehyde ndi nthunzi ya madzi.
(3) Kusintha kwa Madzi Oyambitsa Chinyezi:
Formaldehyde imasinthidwanso kukhala formic acid mu liquid-phase reaction.
(4) Kulekanitsa ndi Kuyeretsa:
Zinthu zomwe zimayamwa zimalekanitsidwa ndikuyeretsedwa pogwiritsa ntchito njira monga distillation kapena crystallization.
