  • Method for oximating organic carbonyl compounds and/or ch-acid compounds
    Publication number: 20030163001
    Abstract: The invention relates to a method for oximating organic carbonyl compounds and/or CH-acid compounds, wherein at least one organic carbonyl compound and/or CH-acid compound in a liquid or dissolved form is mixed with at least one oximating agent in a liquid or dissolved form in at least one microreactor, is reacted during a residence time and the organic oxime thus formed is optionally isolated from the reaction mixture.
