| titleOfInvention | A kind of method for continuously preparing alkyl diolamine pentafluoropropionate |
| abstract | The invention discloses a method for continuously preparing alkyl diolamine pentafluoropropionate, which mainly includes the following steps: (1) completely dissolving N-alkyl diolamine in an organic solvent and transporting it to a drying device Circulating dehydration is carried out; (2) the dried N-alkyl diolamine solution is mixed with anhydrous hexafluoropropylene oxide in a high-efficiency mixer, and then enters a tubular reactor for reaction to obtain alkane containing pentafluoropropionate Product stream of base glycol amine monoester, alkyl glycol amine diester pentafluoropropionate, N-alkyl glycol amine; reaction temperature is ‑30℃～30℃, and reaction pressure is 0.1bar～3.0bar , the reaction residence time is 20min～120min, the molar ratio of hexafluoropropylene oxide and N-alkyl diolamine is 1:1.5～3; (3) The product stream of step (2) passes through the material filled with metal fluoride processor, and then through post-processing such as gas-liquid separation, vacuum distillation, drying, etc. to obtain alkyl diolamine pentafluoropropionate. The invention has the characteristics of continuous and stable process, high reaction yield and easy product separation, and is mainly used for the continuous preparation of 2,2,3,3,3-pentafluoropropionate alkyl diolamine ester. |
