Latest Patents

Deng's latest patents include a process for producing N-methyl or N,N-dimethyl amines. This innovative process utilizes amine compounds, nitro-containing compounds, or nitrile compounds as starting materials. It employs carbon dioxide as a methylating agent and hydrogen gas as a reducing agent. The reaction occurs in a sealed reactor for 6 to 48 hours at temperatures ranging from 80 to 180 °C, in the presence of a composite catalyst. This method is not only simple but also operates under relatively mild conditions, allowing for high yield and low-cost production. Additionally, the catalysts used are highly active and can be easily separated and reused, making the process environmentally friendly by facilitating the cycling use of carbon dioxide.

Another significant patent by Deng is a method for producing N-substituted amine compounds through catalyzed alkylation. This method involves using amine and alcohol or two types of amines as reaction materials. It employs composite metal oxides as catalysts at temperatures between 80-180 °C for 6-36 hours. The reaction conditions are moderate, utilizing inexpensive non-noble metal catalysts that are non-caustic and easy to separate and reuse. This method also does not require any medium, achieving a relatively high conversion rate and selectivity.
