AI Technical Summary
Existing diethyltoluene diamine synthesis technology suffers from problems such as large catalyst consumption, strong corrosivity, complex post-reaction processing, environmental unfriendliness, and low catalytic efficiency, making it difficult to achieve highly selective and high-yield alkylation reactions under mild conditions.
A multi-metal-oxygen cluster-organic framework hybrid material is used as a catalyst. Active functional groups and metal ion coordination are introduced through a multi-step preparation process to form a catalyst with a unique two-dimensional layered structure. This catalyst is used for the alkylation reaction of m-toluenediamine and ethylene. The catalytic efficiency is improved by precisely controlling the reaction conditions and product separation methods.
It significantly improves the yield and selectivity of diethyltoluene diamine, reduces production costs, simplifies the separation and recovery process of the catalyst, conforms to the principles of green chemistry, and has good prospects for industrial application.
