Abstract：The project runs well and reaches the main target of assignment book. In the first part， for the clean manufacture technology of MMA， the technology parameter in catalytic process was clarified by using theory of system engineering. The design of the separation technology in selection oxidation of isobutene and simulation of the full process were finished. The optimal technology process was proposed. The reaction facilities were defined. The production of the catalyst in kg scale was finished. The fundamental data pacage for technology in 1 000 t scale was provided. The design of the process and the construction of devices were finished. In the second part， for the green manufacture technology of 16-DPA， the construction of demonstration production line of 16-DPA in 40 T/year scale was finished. The manufacture parameters was optimized in the production line. The total yield of 16-DPA reached 68% and the purity reached 98%. In laboratory， we try to use LED as light sources to replace Hg lamp to produce 16-DPA， and the results are satisfied. In the third part， for the clean technology of insulating oil， the best ionic liquid was selected to synthesis of insulating oil. The ionic liquid can cycle for more than 30 times without changing of its activity. The production line for the ionic liquid in 100 T/year was constructed. And the catalysis synthesis of insulting oil PEPE in 1 000 T/year scale was began to constructed.
