| titleOfInvention | A kind of device and method for continuous kettle type production of pyrimethamine sulfonate |
| abstract | The invention discloses a continuous kettle type device and method for producing pyrimethamine sulfonate, comprising a toluene storage tank, a triethylamine storage tank, a dimethylaminosulfonyl chloride storage tank, a transfer pump, and a pyrimethamine-toluene mixing tank. Kettle, pyrimethamine toluene dropping still, first reactor, second reactor, third reactor, fourth reactor, crude product receiving reactor, condenser, tail gas system and S-type connecting pipe; the first reactor, The pyrrolizidine toluene mixing kettle and the pyrimethamine toluene dropping kettle are arranged in order from top to bottom; the pyrrolidinol toluene dropping kettle, the reaction kettle and the crude product receiving kettle are provided with condensers, and the condenser is communicated with the reaction kettle, and the reaction kettle is provided with a condenser. The crude product receiving kettle is arranged on the right side, the lower end of the reaction kettle and the upper end of the reaction kettle, and the lower end of the reaction kettle and the upper end of the crude product receiving kettle are communicated through S-shaped pipelines, and the lower ends of the reaction kettle and the crude product receiving kettle are all provided with discharge pipes. Compared with the intermittent production process, the invention greatly reduces the labor intensity of workers and greatly increases the production capacity of pyrimethamine sulfonate. |
