In halogenation step, what we concerned was if hydrochloric acid could be used to substitute thionyl chloride, which is irritant, noxious material and causes severe environmental pollution.
Oxidation route is pretty feasible because Wittig reagent (7) can be obtained easily from available material benzyl chloride.

Thus the material flows are collected together inside the circular region of the dynamic network.
AGVs, labors and belt conveyers can be adopted for the transportation of the material flows inside the circular region.

Base management team set up performance evaluation system according to the situation of participating in research projects, application value and market value of the projects, daily work performance and achievements of science and technology of the graduate students.
So school tutors are responsible for the guidance of graduate thesis is reasonable, but enterprise tutors have to provide assistance, such as provide relevant project materials etc.
