| titleOfInvention | Method for preparing Tetrakis (hydroxymethyl) phosphonium chloride |
| abstract | The invention relates to a method of preparing Tetrakis (hydroxymethyl) phosphonium chloride, Comprising adding hydrochloric acid and formaldehyde into a reaction vessel 1, Opening a gas-liquid mixing reaction pump 2, Adding hydrogen phosphide into the gas-liquid mixing reaction pump 2, Then absorbing hydrogen phosphide through gas-liquid mixing reaction apparatus at a temperature of 50 to 60 degrees, The unabsorbed hydrogen phosphide entering a next gas-liquid mixing reaction apparatus, Determining reaction terminal point by detecting formaldehyde content in process, Decompressing and condensing to achieve Tetrakis (hydroxymethyl) phosphonium chloride after the reaction, The invention has advantages of simple method, Low cost, 40% of reaction speed improving, Non obstruction appeared in equipment, Easy equipment installation and simple operation, And suitable for industrialization production of exhaust gas reutilizationoun. |
