摘要:
Process for pickling polyamide,
comprising the steps
a) contacting the polyamide with a pickling solution comprising
a mixture of at least two inorganic acids
MHF2, where M is an alkali ion or an ammonium ion
a monocarboxylic acid with 1 to 5 carbon atoms
b) contacting with an organic solvent having 1 to 10 carbon atoms, wherein
steps a) and b) take place consecutively or simultaneously.
