The Research on the Preparation, Characterization and Catalytic Properties of Tetracarboxylic Phthalocyanine
Abstract：At present, environmental problems have become the focus of attention of the international community one. Therefore, related to the green chemistry arises at the historic moment, and the related all sorts of green chemical synthesis method; process much the attention of people. The oxidation of hydrocarbons is organic synthesis and industrial use of important method, oxidation process ninety percent is catalytic oxidation process currently used catalytic system mainly has two kinds: one kind is the traditional chemical catalysis, enzyme catalysis is a kind of nature. Compared with the chemical catalytic enzyme catalysis, not only reaction conditions severe, and there are many side effects, so that the product yield and selectivity is lower, at the same time cause high energy consumption and large waste of resources, but also the existence of production equipment corrosion and environment pollution.
Oxidation reaction is one of the main reactions in fine chemicals production, the product of oxidation of olefins reaction is intermediates in a lot of organic synthesis. Oxidants are mainly used by oxidation of olefins, tertiary butyl peroxide hydrogen peroxide, and chlorine between benzoic acid and so on, these antioxidants are more or less having certain drawbacks. The current research mainly focuse on the exploration of new green catalytic oxidation system.
This paper explores new bionic water-soluble catalyst preparation and applications in the olefin epoxidation and allylic oxidation reaction. We explore reasonable catalytic oxidation reaction condition with oxygen as oxidant.
Key Words: phthalocyanine; olefin; allylic oxidation; epoxidation
