Latest Patents

One of his latest patents is titled "Process for preparation of acyclic ethyleneamines." In this invention, at least one of ammonia and ethylenediamine is reacted with monoethanolamine in the presence of a catalyst containing phosphoric acid or its condensate. This process allows for the preparation of acyclic ethyleneamines, and the catalyst's performance can be enhanced and its lifespan prolonged by introducing a phosphorus-containing material during the reaction. Additionally, the catalyst can be reactivated by adding the phosphorus-containing material if its performance deteriorates.

Another significant patent is the "Preparation process of ethylene oxide." In this process, ethylene is oxidized into ethylene oxide by contacting a feed gas mixture containing ethylene, oxygen, and at least 1 vol. % of carbon dioxide with a catalyst that carries silver and rubidium. The specific atomic ratio of rubidium to silver is maintained between 2/1000 and 7/1000 on a fire-resistant carrier with a specific surface area of 1 m²/g or smaller.
