Title: Innovations of Hideaki Ozeki
Introduction
Hideaki Ozeki is a notable inventor based in Annaka, Japan. He has made significant contributions to the field of organohalosilanes, holding a total of 2 patents. His work focuses on improving processes that enhance the efficiency and safety of chemical reactions.
Latest Patents
Ozeki's latest patents include a co-catalyst and process for the preparation of organohalosilanes. In this invention, organohalosilanes are prepared by reacting metallic silicon particles with an organohalide in the presence of a copper catalyst and a co-catalyst. The co-catalyst used is a powder of co-catalyst active element-copper alloy that contains substantial strain energy. This innovation addresses the outstanding problem in the Rochow reaction by reducing the activation time until a steady state is reached, maintaining that steady state over time, and increasing the selectivity of the desired diorganodihalosilane, ultimately enhancing the yield based on the starting silicon.
Another significant patent by Ozeki is the preparation of diorganodichlorosilane. This process involves subjecting organochlorosilanes to a disproportionation reaction in the presence of a SiH group-containing compound and a primary catalyst of AlCl or AlBr. The co-catalyst can be selected from a range of elements such as Mg, Al, Ca, Ti, Fe, Ni, Cu, Zn, or Sn. This invention allows for the disproportionation reaction of organochlorosilanes to occur under atmospheric pressure and at low temperatures, improving the safety and simplicity of the reaction equipment.
