Abstract
The present invention relates to processes for reducing or eliminating the amount of hydrazine from a hydroxylamine-free base containing hydrazine by treating said hydroxylamine-free base with a scavenger agent, and to the hydroxylamine-free base thereby obtained, as well as to its use for producing microdispersions containing a hydroxamated polymer for use as a flocculant in the Bayer process.
