| titleOfInvention | A kind of process for purification and process unit of anhydrous pure formaldehyde gas |
| abstract | The invention discloses a kind of process for purification and process unit of anhydrous pure formaldehyde gas, the technique is introduced a kind of water insoluble and not reacted with water, and the assistant agent for only being reacted with formaldehyde, the assistant agent reacts with formalin and obtains hemiacetal reactant, the hemiacetal reactant is water insoluble, and the small heat-sensitive substance of density ratio water, back reaction decomposition is susceptible under the too high environment of temperature, pure formaldehyde gas and liquid adjuvants are obtained by heat resolve.Present invention process is simple, energy consumption is low, simple to operate, and effect on environment is smaller. |
