Abstract:The syntheses and it‘s bioactivity of haloaminophosphatidic lignin was studied. The aim of syntheses is to obtain the haloaminolignin by halogenation and amination of lignin separated from the waste liquor of papermaking factory at first, and then reacted with alky1-phosphochloride to get the haloaminophosphatidic lignin. The compound has higher bioactivity to the bacteria through the bacteriostasis testing.
