Formic Acid Gas-Phase hmanga hman dan
Gas-phase method hi formic acid siamna atana hmanraw thar zawk a ni. Process flow chu hetiang hi a ni:
(1) Raw Material siam dan: 1.1.
Methanol leh boruak siam a ni a, methanol chu tihthianghlim leh tui paih chhuah a ni.
(2) Gas-Phase-a Oxidation Reaction awm dan: 1.1.
Methanol pretreated chu catalyst awmnaah oxygen nen an inrem a, formaldehyde leh water vapor a siam chhuak thin.
(3) Catalytic Liquid-Phase hmanga thil tih dan: 1.1.
Formaldehyde chu liquid-phase reaction-ah catalytically-in formic acid-ah a inthlak leh ta a ni.
(4) Inthen leh Thianghlimna: 1.1.
Reaction products te hi distillation emaw crystallization ang chi hmangin an inthen a, an tithianghlim thin.
