| titleOfInvention | Phase transfer catalytic process for synthesis of N-butyl perfluorooctanesulfonamide |
| abstract | The invention relates to a phase transfer catalysis technology. The invention aims to provide a phase transfer catalytic process for synthesis of N-butyl perfluorooctanesulfonamide. The phase transfer catalytic process is as follows: adding a solvent in a reaction kettle equipped with a stirrer, a thermometer, a condenser and a feeding tube, the adding n-butylamine and a phase transfer catalyst, adding perfluorooctanesulfonyl fluoride into the feeding tube, dripping the perfluorooctanesulfonyl fluoride in the feeding tube into the reaction kettle in ice bath cooling, stirring for two to six hours, cooling, performing vacuum filtration on a reaction liquid, washing with hot water for 3-4 times, washing for one time with 0.5% dilute hydrochloric acid, finally washing with water for 2-3 times, performing vacuum filtration, and recrystallizing a filter cake with ethanol to obtain the N-butyl perfluorooctanesulfonamide. The beneficial effects of the phase transfer catalytic process are that: reactants are in oil and water two phases, reaction time is long, conversion rate is low, by adding of the phase transfer catalyst, the reaction rate can be accelerated, the reaction energy consumption is reduced, and the product N-butyl perfluorooctanesulfonamide yield is improved. |
