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.
