AI Technical Summary

Technical Problem

Existing catalysts for producing allyl acetate from propylene, acetic acid, and oxygen suffer from inferior performance when compared to those used for vinyl acetate production, leading to inefficiencies and higher production costs.

Method used

A catalyst comprising palladium, ruthenium, at least one element selected from copper, nickel, zinc, and cobalt, and an alkali metal salt supported on a carrier, with specific mass ratios and preparation methods to enhance activity and selectivity.

Benefits of technology

The catalyst achieves high space-time yield and selectivity for allyl acetate production, reducing production costs and improving efficiency.
