Propionic acid leh propionic acid ethanol carbonation siam dan hi eng nge ni?
2. 2. A rilru a hah lutuk chuan a rilru a buai em em a025-10-14 ah biak theih a ni
Propionic Acid hmanga siam a ni leh propanoic acid Ethanol Carbonylation Method hmanga siam a ni
Hetiang method hi a tirah chuan A company te siam a ni. Acidic medium 250–350°C leh 10–30 MPa-ah chuan catalyst boron trifluoride, carbon tetrachloride, copper acetate, halides of manganese, aluminum, nickel, cobalt, emaw iron, leh chromium, molybdenum emaw tungsten acids te hmangin liquid phase-ah ethanol chu carbon monoxide nen inrem in propionic a siam chhuak thin acid, a yield chu 90% a ni. Mahse, thil chinfel loh, reaction rate, yield, catalyst hloh, leh temperature leh pressure sang tak hnuaia equipment corrosion te avang hian he method hi propionic acid leh propanoic acid industry-ah chuan hman a la ni lo hle.
