| titleOfInvention | Continuous production system and method for methyl tetrahydrophthalic anhydride |
| abstract | The invention discloses a continuous production system and a continuous production method of methyl tetrahydrophthalic anhydride, wherein the production system comprises a tower reactor, a carbon five storage tank, a maleic anhydride storage tank, a film evaporator, a carbon five receiving tank, an adiabatic evaporator and a finished product tank, the carbon five storage tank is connected with the tower reactor through a first magnetic pump, the maleic anhydride storage tank is connected with the tower reactor through a second magnetic pump, the tower reactor is connected with the film evaporator, the film evaporator comprises a steam outlet and a liquid outlet, the steam outlet is connected with the carbon five receiving tank through a first condenser, the liquid outlet is connected with the adiabatic evaporator, a catalyst fixer is arranged between the liquid outlet and the adiabatic evaporator, and the adiabatic evaporator is connected with a second condenser through a third magnetic pump and then is connected with the finished product tank. The continuous production system of the methyl tetrahydrophthalic anhydride really realizes the continuous production of the methyl tetrahydrophthalic anhydride, improves the efficiency by about 200 percent compared with the traditional process, has more thorough reaction, reduces the investment of five carbon atoms, reduces the energy consumption, and improves the yield and the quality of the product. |
