Method for improving activity of propylene epoxide catalyst and co-producing ketal (acetal)

The invention provides a method for synthesizing propylene epoxide and co-producing ketal (acetal) by taking a by-product PG as a raw material in propylene epoxidation in the presence of heteropoly acid as a catalyst. Negative effects of alcohol substances to the activity of the catalyst in epoxidation reaction are eliminated, the activity of the catalyst is improved, the catalyst is used stably,meanwhile, downstream application of the by-product PG is expanded, and a preparation method for ketal (acetal) is provided. The method has the advantages of gentle reaction conditions, good catalyzing stability, good catalyst using effect, and resource utilization of the by-product.

preliminary aldehyde (C 2-C 10) propylene glycol acetal synthetic method (by machine translation)

The invention discloses a synthetic method of low-grade aldehyde (C2-C10) propylene glycol acetal. A target object is prepared from low-grade aldehyde (C2-C10), 1, 2-propylene glycol, anhydrous calcium chloride and p-toluenesulfonic acid which are reacted in the method. By adopting the method disclosed by the invention, the reaction is free from byproducts and pollution, the product purity and the product recovery rate are high, the cost is low, the efficiency is high and the fragrance is good. Through simple stirring reaction, the content of the acetal can reach condensation over 98%, and the method is applicable to mixing various high-grade essences and has a considerable effect of increasing the stability and temperature resistance of an essence finished-product.

PROCESS FOR MAKING POLYOL ETHERS

The present invention generally relates to a process for making polyol ethers by reacting a polyol and a carbonyl compound together in the presence of hydrogen gas and a bimetal palladium hydrogenation catalyst on a carbon support.
