From a research point of view continuously disclosed, used in the oxidation reaction of the catalyst of TS-1 is green oxidant, hydrogen peroxide, having a reactive conditions moderate and product selectivity characteristics is expected to overcome some of the traditional process in serious pollution and reaction conditions are harsh, etc. shortcomings, has potential advantages for the development of environmentally friendly new chemical process. The new titanium silicalite (HTS-1) compared to conventional titanium silicalite (TS-1), HTS-1 the novel hollow configuration of the new titanium silicalite (HTS-1) is an international initiative, at the international advanced level. China has the HTS-1 as a special catalytic material caprolactam production with independent intellectual property rights and successfully applied to the development of new technology, the titanium silicalite HTS-1 preparation method development, as well as the expansi
