| titleOfInvention | Refining system of nitromethane |
| abstract | The utility model provides a refined system of nitromethane, refined system includes: a rectification apparatus, comprising: the first membrane filtration unit (100), the first membrane filtration unit (100) is located between the first condenser (300) and the return line (400) at the top of the rectification tower, the first membrane filtration unit (100) contains a first membrane (110), and the first membrane (110) is an oleophilic hydrophobic membrane for separating nitromethane from a water phase. The utility model discloses a nitromethane's refining system can detach impurity such as moisture in nitromethane crude product and the prerefining product fast, high-efficiently, reduces rectification reflux number of times and rectification reflux time, improves the purity and the yield of nitromethane product, reduces the rectification energy consumption, and is easy and simple to handle, swift, has extensive application prospect. |
