Liquid ammonia method - Ekitai anmoniaho

…The Zahn process (intermediate salt process) adds solid NH 4 HCO 3 to a solution containing other easily soluble sodium salts NaX (X = SO 4 , NO 3 , etc.) to precipitate NaHCO 3. The liquid ammonia process (liquid ammonia process) uses the high solubility of NaCl in liquid NH 3 to produce sodium carbamate, which is then decomposed with steam to obtain NaHCO 3. NaCl + NH 3 + CO 2 - → NaCO 2 NH 2 + NH 4 Cl NaCO 2 NH 2 + H 2 O - → NaHCO 3 + NH 3Pressurized A process is carried out by pressurizing the CO 2 to several tens of atmospheres, but the overall reaction rate of A process is not that favorable. …

…ツァーン法(中間塩法)は易溶性の他種ナトリウム塩NaX(X=SO4,NO3など)を共存させた溶液に固体NH4HCO3を添加し,NaHCO3を析出させる。液体アンモニア法(液安法)はNaClが液体NH3に対し高溶解性をもつことを利用し,カルバミン酸ナトリウムをつくり,これを水蒸気分解してNaHCO3を得る。 NaCl+NH3+CO2―→NaCO2NH2+NH4Cl NaCO2NH2+H2O―→NaHCO3+NH3加圧下ア法はCO2圧力数十気圧まで加圧して行う方法であるが,ア法全体として反応率がそれほど有利にはならない。…
