Versuchsvorschrift

After the active carbon treatment, solids are deposited by salting out with addition of concentrated hydrochloric acid, and an amount of added hydrochloric acid may be 4-20 times by mole of 4,6-diaminoresorcinol. It is influenced by the amount of water from the economical viewpoint, but 4-8 times by mole are preferable. 4,6-Diaminoresorcinol dihydrochloride is obtained by drying after filtration.
