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.

Highly effective tandem hydroformylation-acetalization of olefins using a long-life Bronsted acid-Rh bifunctional catalyst in ionic liquid-alcohol systems

A robust and highly effective tandem hydroformylation-acetalization of olefins using a Bronsted acid-Rh bifunctional catalyst (ARBC) in ionic liquid-alcohol systems is reported. The key feature of the ARBC is its use of a zwitterionic phosphine ligand bearing an amino acid tag. This novel ARBC shows an excellent catalytic efficiency and a long service life without a significant drop in both the hydroformylation efficiency and the acetalization efficiency or Rh loss for more than seventeen cycles. We believe that the long-term high activity and acetal selectivity mainly benefit from the synergy between the acidic active site and the Rh active site on the ARBC and the highly effective immobilization and recycling of ARBC in ionic liquid-alcohol systems due to the strong affinity of ARBC for the ionic liquid.
