摘要：
A method for decomposing an aromatic aldehyde-hydrogen fluoride-boron trifluoride complex in the presence of a decomposing agent represented by the formula ##SPC1##Wherein n is integer of 1-6, inclusive, and m is integer of 0-5, inclusive, and a total of n and m is 6 or less, to obtain an aromatic aldehyde, hydrogen fluoride and boron trifluoride separately without causing any change in the quality of the aromatic aldehyde or without forming undesirable byproducts is disclosed.
