Solubility: Easily soluble in water, low alcohol, glycerol, N,N-dimethylformamide, partially soluble in acetone, ethyl acetate, slightly soluble in carbon tetrachloride , ether and chloroform, insoluble in aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons. Its hygroscopicity is about 50 times that of glycerol.

N-butyraldehyde and formaldehyde undergo a condensation reaction under alkaline conditions. The reaction solution is concentrated and desalted, and then decolorized and purified with ion exchange resin. Finally, it is evaporated, cooled and rolled with a thin film evaporator. Get the finished product.
