ABSTRACT:
The present invention relates to a process for manufacturing sulfonylaminocarbonyl triazolinones and salts thereof, which are herbicidally active compounds, wherein the improvement comprises conducting the conversion reaction of the sulfonylaminocarbonyl triazolinone to a salt thereof under pH controlled conditions. In particular, this invention relates to the conversion of a substituted triazolinone to a sulfonylaminocarbonyl triazolinone, and without the isolation of this intermediate product, the sulfonylaminocarbonyl triazolinone is then converted to a salt thereof.
