RECOVERY OF VOLATILE ACIDS

摘要

PURPOSE:To perform the recovery of volatile acids requiring no separation or decomposition treatment after recovery without requiring an excessive chemical agent and a large quantity of power. CONSTITUTION:Volatile acids are recovered by bringing a waste solution containing volatile acids into contact with amines with a b.p. of 50 deg.C or higher to make acids in the waste solution ionically adsorbed and subsequently heating amines to discharge adsorbed acids.
